## Background
CROSS REFERENCE TO RELATED APPLICATIONS
This application claims the benefit of U.S. patent application Ser. No. 12/651,051, filed on Dec. 31, 2009, now allowed, which is hereby incorporated by reference in its entirety.
BACKGROUND OF THE INVENTION
Recording has become a key feature of modem interaction-related environments and/or systems. For example, systems used for operating call centers, banks, academic institutions, government agencies, health care facilities and/or web based shopping may all comprise some form of recording capacities and/or systems. Interactions involving customers, clients, constituents or any other users associated with various respective industries, organizations and companies may all be recorded or may be selectively recorded according to various criteria. Recording of calls or communication sessions may be mandatory for some organizations, used as voice receipt or used for tracking, logging or other purposes.
Recording of calls may be performed at the end-devices. For example, in a peer-to-peer network, a computer application may record communication sessions using a recording agent for capturing communication sessions signaling and communication sessions media. However, such solutions may not be available or feasible for various scenarios as they may require installation of additional hardware or software on each endpoint that needs to be recorded. Additionally, recording at the endpoints may be highly distributed, which may cause central management of recording to be difficult or cumbersome. Recording at the endpoint may not be applicable for compliance requirements. For example, recording at the endpoint may not comply with the law or may be objected due to privacy issues.

Although embodiments of the invention are not limited in this regard, the terms “plurality” and “a plurality” as used herein may include, for example, “multiple” or “two or more”. The terms “plurality” or “a plurality” may be used throughout the specification to describe two or more components, devices, elements, units, parameters, or the like. Unless explicitly stated, the method embodiments described herein are not constrained to a particular order or sequence. Additionally, some of the described method embodiments or elements thereof can occur or be performed at the same point in time.
Reference is made to FIG. 1 depicting a high-level diagram of an exemplary peer-to-peer communication network 100 according to embodiments of the invention. According to embodiments of the invention, system 100 may comprise a plurality of end-devices 110 and super-nodes 120, an authentication server 140 and a recording system 130.
Peer-to-peer communication network 100 may be any distributed network architecture composed of participants such as end-devices 110 and super-nodes 120 that make a portion of their resources such as processing power, disk storage or network bandwidth directly available to other network participants, without the need for central coordination instances such as servers or stable hosts. Network 100 may be, for example, a packet based peer-to-peer communication network. Peer-to-peer communication network 100 may utilize Voice over Internet Protocol (VoIP) technology to establish telephone sessions or calls between end-devices 110. Peer-to-peer communication network 100 may comprise infrastructure nodes such as super-nodes 120 to perform infrastructure related tasks. Typically, end-devices 110 may be connected to a super-node 120 and each such end-device 110 may register itself with authentication server 140. For example, super-nodes 120 may function as proxy servers and subgroups of end-devices 115 may connect to a single super-node 120 in a star-like fashion. End devices 110 may communicate by passing media and signaling related to a communication sessions through super-nodes 120.
End-device 110 may be any device that can originate or receive a communication session in the peer-to peer communication network 100. For example, end-devices may be dedicated VOID phones which are phones that allow VOID calls without the use of a computer, VOID-capable computers, routers, and gateways within the peer-to-peer communication network 100 or plain old telephone service (POTS) dial peers such as phone sets, cell phones, and fax machines, connected to peer-to-peer communication network 100 through an adaptor such as an Analog Telephone Adapter (ATA). Additionally, end-device 110 may be coupled to an automatic call distributor (ACD) of a call center and/or to an interactive voice response (IVR) sub-system.
An IVR sub-system may perform an initial interaction with incoming communication sessions. For example, an IVR sub-system may gather information pertaining to an incoming communication session. Such information may be, for example, a caller identification (CID). An IVR sub-system may further provide a voice-menu in order to prompt a caller to provide further information pertaining to the communication session and/or the caller. An ACD sub-system may select one of agents 140 to handle an incoming communication session and may further forward a communication session to the selected agent.
It will be noted that although a communication session enabling two or more humans or other entities (e.g., a human caller and an IVR application) to communicate will typically be referred to hereinafter as a communication session, the term “communication session” should be expansively and broadly construed to include any applicable session or interaction. A communication session may be a telephony session, an instant massaging session, a video session, a chat session, a web co-browsing session or any other applicable type of multi-media interaction. Web co-browsing session, also referred to as collaborative browsing may refer to several people accessing the same web pages at the same time. For example, web co-browsing may be used by call center agents to assist clients navigate the company web site. A communication session may be, for example, a telephone call carried over a packet based network, such as voice or voice, video and other data over Internet Protocol (VoIP) session. A communication session data may be divided to the communication session signaling which is the traffic used to establish the connection, and to the media which is voice, video or any other type of information that is transferred between end-devices 110 in the communication session.
Accordingly, recording a communication session media may comprise recording any applicable information, e.g., audio, video, text etc. It will further be noted that a caller or end user may be any applicable entity, e.g., a user, a customer or client, or an organization such as academic institution, a government agency, a service provider or a call center providing services to, or acting as a front end for a business, a company, an institution or any other applicable organization.
According to embodiments of the invention, system 100 may additionally comprise recording super-nodes 125. Recording super-nodes 125 may have super-nodes capabilities and, in addition, function as dedicated recording servers. Once a communication session is established, recording super-nodes 125 may fork media associated with the communication session to recording system 130, which may record the communication session. The term “fork” may be used throughout the specification to describe the process of creating duplicate of media of a communication session to be sent to a destination other than the destination of the respective communication session. For example, recording super-nodes 125 may transfer media between the communication session endpoints 110, create duplicate of this media and send the duplicate to recording system 130.
According to embodiments of the invention, recording super-node 125 may be assigned to end-devices 110 that need to be recorded, and end-devices 110 that need to be recorded may register with recording super-node 125. For example, end-devices 110 that need to be recorded may receive an instruction to register with a recording super-node 125 from authentication server 140 on end-device 110 login. Additionally, end-devices 110 that need to be recorded may receive a list of recording super-nodes 125 to register with from authentication server 140 on end-device 110 login.
According to embodiments of the invention, associating end-devices 110 to a recording super-node 125 may be based on static entries in authentication server 140 recording database. Upon an end-device 110 login, authentication server 140 may retrieve the address of recording super-node 125 from the recording database, in case end-device 110 needs to be recorded, and return the address of recording super-node 125 to end-device 110.
Alternatively, authentication server 140 may be in communication with recording system 130. Upon an end-device 110 login, authentication server 140 may provide the identity of end-device 110 to recording system 130 together with a query whether end-device 110 should be recorded. Recording system 130 may decide whether end-device 110 should be recorded. If end-device 110 should be recorded, recording system 130 may choose the recording super-node 125 and may provide the address of the chosen recording super-node 125 to authentication server 140, which may provide that address to end-device 110. End-device 110 may then send a request to register with the selected recording super-node 125. Alternatively, other suitable protocols may be used to assign end-devices 110 to recording super-nodes 125. Authentication server 140 may communicate with recording system 130 utilizing Web Services (WS) standard for inter-system communication. Alternatively, other suitable communication protocols may be used.
According to embodiments of the invention, multiple recording super-nodes 125 may be deployed in a network together with load balancing application that may distribute communication traffic among recording super-nodes 125. Redundancy may be implemented by coupling two recording super-nodes 125 in an active/standby mode.
According to embodiments of the invention, any super-node 120 may be used as a recording super-node. Super-nodes 120 may have the address of recording system 130. For example, super-nodes 120 may learn the address of recording system 130 from authentication server 140. The address of recording system 130 may be either statically configured in authentication server 140 database, or can be learned by authentication server 140 from an external source such as a load balancing service, another server, some global public directory, the Active Directory by Microsoft, etc. End-devices 110 may register with any one of super-nodes 120. Super-node 120 may establish an auxiliary session with recording system 130 for reporting communication session or call events. For example, super-node 120 may communicate with recording system 130 using NICE® Distributed Interaction Metadata Messages (IMM) protocol over Session Initiation Protocol (SIP) transport, as described in US patent application publication No. 2007\0019634 which is hereby incorporated by reference in its entirety. Alternatively, other communication protocols suitable for metadata delivery such as Hypertext Transfer Protocol (HTTP) or WS may be used.
After a communication session is established with end-device 110 through super-node 120, super-node 120 reports the communication session event to recording system 130 over the auxiliary session. Recording system 130 may determine whether the communication session should be recorded. If the communication session should be recorded, recording system 130 may issue a recording request to super-node 120. For example, recording system 130 may establish SIP session with super-node 120 instructing it to fork communication session media associated with the communication session to recording system 130. Super-node 120 may then start forking the communication session traffic to recording system 130. When the communication session ends, super-node 120 may report a communication session end event to recording system 130 and recording system 130 may than terminate the recording. According to embodiments of the invention, the SIP session between recording system 130 and super-node 120 may comply with the SIP session for recording purposes as described in US publication No. 2007-0019634 which is hereby incorporated by reference in its entirety.
According to embodiments of the invention, when any super-node 120 is used as a recording super-node, redundancy and load balancing may be implemented by the peer-to-peer communication network 100 itself. Load balancing may be implemented by distributing endpoints 110 between network super-nodes 120, as in typical peer-to-peer networks. Redundancy may also be inherent to the peer-to-peer network. In case of super-node 120 failure, end-devices 110 that were connected to the defected super-node 120, may be assigned to a different super-node 120 which may connect with recording system 130 as explained above to continue the recording.
Typically, the media that is forked by super-node 120 to recording System 130 may be not encrypted. However standard encryption mechanisms like Transport Layer Security (TLS) for call meta-data and signaling and Secure Real-time Transport Protocol (SRTP) or Datagram Transport Layer Security for Secure Real-time Transport Protocol (DTLS-SRTP) for encrypted media may be utilized by the network. If TLS and SRTP or DTLS-SRTP security method is utilized, a Public Key Infrastructure (PKI) may exist. The PKI may be responsible for issuing digital certificates for both super-node 120 and recording system 130. Alternatively, super-node 120 may already have digital certificate, issued by authentication server 130 during registration. The same authentication server may, for example, issue digital certificate for recording system 130 as well. Typically, end-devices 110 are issued a digital certificate by authentication server 130 on end-device 110 login.
Reference is now made to FIG. 2 which is a flowchart illustration of a method for registering an end-device with a recording super-node upon login to a peer-to-peer communication network according to embodiments of the invention. According to embodiments of the invention, when a login request arrives from an end-device (block 200) to a peer-to-peer communication network it is decided whether the end-device should be recorded (block 210). For example, when a login request from an end-device arrives at an authentication server of a peer-to-peer communication network, the authentication server may decide that the end-device need to be recorded based on static entries in the authentication server recording database. Alternatively, the authentication server may be in communication with a recording system and may provide the identity of the end-device to the recording system together with a query whether the end-device should be recorded. The recording system may decide whether the end-device should be recorded. If the end-device should be recorded, the recording system may choose a recording super-node and may provide the address of the chosen recording super-node to the authentication server. If the end-device should be recorded, an address of a recording super-node may be provided to the end-device (block 240). The end-device may then register with the recording super-node (block 250). If the end-point should not be recorded, address of a standard, i.e. not-recording super-node may be provided to the end-device (block 220). The end-device may then register with the standard super-node (block 230).
Reference is now made to FIG. 3 which is a flowchart illustration of a method for recording peer-to-peer communication sessions according to embodiments of the invention. As seen in block 300 end-devices of the peer-to-peer communication network may register with a selected super-node. The selected super-node may be a dedicated recording super-node, such as, but not limited to, recording super-node 125. For example, end-devices may send a request to an authentication server to register to the peer-to-peer network. The authentication server may receive the registration request from the end-device. End-devices that need to be recorded may receive an instruction to register to a selected super-node and a list of selected super-nodes to register with from the authentication server on end-device login. Alternatively, any selected super-node may be capable of forking media to the recording system. For example, the selected super-node may learn the address of the recording system from the authentication server. After a communication session is established between two or more endpoints (block 310), the media associated with the communication session may be forked to the recording system (block 320), which may record the communication session (block 330).
Reference is now made to FIG. 4 which is a flowchart illustration of a method for using any super-node for recording in a peer-to-peer communication network according to embodiments of the invention. According to embodiments of the invention, super-nodes of a peer-to-peer communication network may get an address of a recording system (block 400). For example, the super-nodes may learn the address of the recording system from an authentication server. End-devices may register with any one of the super-nodes of the peer-to-peer communication network (block 410). Once a communication session is established in the peer-to-peer communication network via a super-node (block 420), a notification of the beginning of the session may be issued (block 430) and it may be decided whether the communication session should be recorded (block 440). For example, a communication session start event may be reported to the recording system. The recording system may determine whether the communication session should be recorded. If the communication session should be recorded, the recording system may issue a recording request. Alternatively, decision whether the communication session should be recorded may be accepted at the super-node. If it is decided that the communication session should not be recorded, the communication session may not be recorded (block 450). If the communication session should be recorded, the media of the communication session may be forked (block 460), and the communication session may be recorded (470).
Reference is made to FIG. 5 depicting a high-level diagram of an exemplary peer-to-peer communication network 500 according to embodiments of the invention. According to embodiments of the invention, network 500 may comprise a plurality of external end-devices 570, at least one super-node 550 and a call center 510 comprising a plurality of agent end-devices 520, an IVR/ACD 530 and a recorder 540. According to embodiments of the invention, network 500 may be coupled through super-node 550 to a communication network 560. Communication network 560 may comprise a peer-to-peer communication network, such as network 100. Additionally, communication network 560 may be coupled to a public switched telephone network PSTN network. It should be noted that while in the embodiments of the invention shown in FIG. 5 IVR/ACD 530 system are depicted as a single integrated system, IVR/ACD 530 system may be separated into two separate systems, IVR and ACD. Alternatively, call center 510 may not comprise IVR system. Additionally, while in the embodiments of the invention depicted in FIG. 5 agent end-devices 520, IVR 525 and ACD 530 are depicted coupled to a single super-node 550, according to embodiments of the invention, agent end-devices 520, and IVR/ACD 530 may be registered to different super-nodes as well.
According to embodiments of the invention, recorder 540 may be placed after the IVR/ACD 530, if only the media transferred between agent end-devices 520 and external end-device 570 needs to be recorded as depict in FIG. 5, or before IVR/ACD 530, if recording the IVR session is required as well (not shown).
According to embodiments of the invention, recorder 540 may comprise two nodes, external node 542 and internal node 544. Each of external node 542 and internal node 544 may have a different and unique identity or address and both may be connected to communication network 500.
According to embodiments of the invention, after a communication session from an external end-device 570 arrives at call center 510, it is first directed to IVR/ACD system 530. IVR/ACD system 530 may collect caller information and choose a target agent end-device 525. IVR/ACD system 530 may than call external node 542 of recorder 540 and send a call request to recorder 540 to call target agent end-device 525 and establish a communication session between recorder 540 and agent end-device 525. For example, sending such a call request can be done by external application programming interface (API) between recorder 540 and IVR/ACD system 530, or by using peer-to-peer communication such as instant message. The request may comprise the number or address of target agent end-device 525, the number or address of external end-device 570 and any other information gathered by IVR/ACD system 530, as may be required.
Upon receiving the call request, recorder 540 may initiate an outgoing communication session on internal node 544 to target agent end-device 525. After the outgoing communication session between internal node 544 and target agent end-device 525 is established, IVR/ACD system 530 may transfer the communication session from an external end-device 570 to external node 542 of recorder 540 and drop from the communication session.
Outgoing communication sessions may pass through the recorder in a similar manner. For example, target agent end-device 525 may initiate a session by calling internal node 544 of recorder 540 and send a call request to recorder 540 to call external end-device 570 and establish a communication session between recorder 540 and external end-device 570. For example, sending such a call request can be done by external application programming interface (API) between recorder 540 target agent end-device 525, or by using peer-to-peer communication such as instant massage. The request may comprise the number or address of target agent end-device 525, the number or address of external end-device 570 and any other information, as may be required. Upon receiving the call request, recorder 540 may initiate an outgoing communication session on external node 542 to external end-device 570.
During the communication session, recorder 540 may act as a proxy, receiving external end-device 570 media on external node 542 and sending it to target agent end-device 525 on internal node 544, and receiving agent end-device 525 media on internal node 544 and transferring it to external end-device 570 on external node 542. Recorder 540 also saves and records copy of the media.
Once the communication session is terminated at one node, recorder 540 may terminate the communication session on the other end stop the recording. For example if external end-device 570 terminates the communication session, recorder 540 may terminate the communication session on internal node 544 and if agent end-device 525 terminates the communication session, recorder 540 may terminate the communication session on external node 542.
According to embodiments of the invention, recorder 540 may have a single node which may perform the functionality of external node 542 and internal node 544.
According to embodiments of the invention, recording communication sessions at peer-to-peer communication network 500 may be achieved by implementing the communication session as a conference call such that target agent end-device 525, external end-device 570 and recorder 540 are participants in the conference call. While connected to the conference call, recorder 540 may receive media transferred between target agent end-device 525 and external end-device 570 and record that media.
For example, after a call from an external end-device 570 arrives at call center 510, and after IVR/ACD system 530 had chosen a target agent end-device 525, IVR/ACD system 530 may create a communication session with target agent end-device 525 and recorder 540, transfer them into a conference call and drop from the communication session. Alternatively, IVR/ACD system 530 may create a communication session with target agent end-device 525 and drop from the communication session. Agent end-device 525 may then create a conference call and add recorder 540 to the conference call. Similarly, outgoing communication sessions initiated by agent end-device 520 may be implemented as a conference call, such that agent end-device 520, external end-device 570 and recorder 540 are participants in the conference call. For example, agent end-device 520 may create a conference call and add recorder 540 and external end-device 570 to the conference call.
Reference is now made to FIG. 6 which is a flowchart illustration of a method for recording communication sessions between an external end-device and an agent end-device over a peer-to-peer communication network according to embodiments of the invention. Although embodiments of the invention are not limited in this respect, the method may be performed by embodiments of the invention, for example, an embodiment as shown in FIG. 5.
According to embodiments of the invention, a communication session is established between an external end-device and a recorder (block 600). The communication session may be established over a selected super-node of the peer-to-peer network. As seen in block 610 another communication session is then established between the recorder and a target end-device. The recorder may pertain to a call center. For example, when the external end-device initiates a communication session, the external end-device may be connected to an IVR/ACD system that may collect caller information and choose a target agent end-device from a plurality of agent end-devices coupled to the IVR/ACD. The IVR/ACD system may than call the recorder and send a call request to the recorder to establish a communication session between the recorder and the target agent end-device. For example, sending such a call request can be done by external application programming interface (API) between the recorder and the IVR/ACD system, or by using peer-to-peer communication such as instant massage. The request may comprise the number or address of the target agent end-device, the number or address of the external end-device and any other information as may be required. The recorder may then initiate a communication session to the target agent end-device and the external end-device may be transferred to the recording system from the IVR/ACD system. Alternatively, in case of outgoing communication session a session is first established between the target agent end-device and the recorder and than a session is established between the recorder and the external end-device via a selected super-node over the peer-to-peer network.
After these sessions are established, communication session media may be transferred between the external end-device and target agent end-device via the recorder (block 620) and the communication session media may be recorded (block 630).
Reference is now made to FIG. 7 which is a flowchart illustration of a method for recording communication sessions implemented as conference call between an external end-device, an agent end-device and a recorder over a peer-to-peer communication network according to embodiments of the invention. Although embodiments of the invention are not limited in this respect, the method may be performed by embodiments of the invention, for example, an embodiment as shown in FIG. 5.
According to embodiments of the invention, a conference call may be established between an external end-device, a target agent end-device and a recorder (block 710) over a peer-to-peer communication network. For example, if an IVR/ACD system of a call center receives a communication session from an external end-device, the IVR/ACD system may create a communication session with the target agent end-device and the recorder, transfer them into a conference call and drop from the communication session. Alternatively, the IVR/ACD system may create a communication session with the target agent end-device and drop from the communication session and the agent end-device may then create a conference call and add the recorder to the conference call. Similarly, for outgoing communication sessions the agent end-device may create a conference call and add recorder and the external end-device to the conference call. After a conference call is established, the recorder may receive media transferred between the external end-device and the target agent end-device and record that media (block 720).
It will be recognized that according to embodiments of the invention, the actual recording of a communication session may be performed in any applicable way as known in the art. For example, any suitable recording server, platform or system, e.g., NICE Perform® from NICE Ltd. of Ra'anana, Israel may be used to record a communication session once a decision to record the communication session has been made. Embodiments of the invention are not limited by the type, nature or other aspects of the recording system used for recording communication sessions as described herein.
Some embodiments of the present invention may be implemented in software for execution by a processor-based system, for example, recording super-nodes 125. For example, embodiments of the invention may be implemented in code and may be stored on a storage medium having stored thereon instructions which can be used to program a system to perform the instructions. The storage medium may include, but is not limited to, any type of disk including floppy disks, optical disks, compact disk read-only memories (CD-ROMs), rewritable compact disk (CD-RW), and magneto-optical disks, semiconductor devices such as read-only memories (ROMs), random access memories (RAMs), such as a dynamic RAM (DRAM), erasable programmable read-only memories (EPROMs), flash memories, electrically erasable programmable read-only memories (EEPROMs), magnetic or optical cards, or any type of media suitable for storing electronic instructions, including programmable storage devices. Other implementations of embodiments of the invention may comprise dedicated, custom, custom made or off the shelf hardware, firmware or a combination thereof.
Embodiments of the present invention may be realized by a system that may include components such as, but not limited to, a plurality of central processing units (CPU) or any other suitable multi-purpose or specific processors or controllers, a plurality of input units, a plurality of output units, a plurality of memory units, and a plurality of storage units.

establishing a peer-to-peer communication session between an agent end-device and an external end-device over a peer-to-peer communication network having one or more super node servers, wherein the peer-to-peer communication session is established via a selected super-node server, wherein establishing the peer-to-peer communication session comprises receiving by an authentication server a request from the external end-device to register with the peer-to-peer network and receiving, by the agent end-device from the authentication server, an instruction to register with the selected super-node server;
implementing the peer-to-peer communication session as a conference call such that the agent and the external end-device are respectively first and second participants in the conference call;
entering a recording system to the conference call as an additional participant, wherein the recording system has at least one peer-to-peer node coupled to the selected super-node server;
receiving, from the authentication server by the selected super-node server, an address of the recording system;
establishing by the selected super-node an auxiliary session with the recording system for reporting communication session events;
determining by the recording system that the communication session is to be recorded; and
recording by the recording system the peer-to-peer communication session through the conference call.

2. The method of claim 1, wherein the communication session is one of a telephony session, an instant massaging session, a video session, a chat session, a web co-browsing session or a voice over Internet Protocol (VoIP) session.

3. The method of claim 1 wherein implementing the peer-to-peer communication session as a conference call is done by an automatic call distributing (ACD) system and the ACD system is coupled to the peer-to-peer communication network.

4. The method of claim 1 wherein implementing the peer-to-peer communication session as a conference call is done by the agent end-device.

5. A system for recording a communication session in a peer-to-peer communication network having one or more super node servers, the system comprising:
a selected super-node server;
an authentication server;
a recording system coupled to the selected super node server; and
a target agent end-device,
wherein the system is configured to establish a peer-to-peer communication session between the target agent end-device and an external end-device over the peer-to-peer communication network via the selected super-node server and to implement the peer-to-peer communication session as a conference call such that the target agent end-device and the external end-device are respectively first and second participants in the conference call and to enter the recording system to the conference call as an additional participant;
wherein establishing the peer-to-peer communication session comprises receiving by the authentication server a request from the external end-device to register with the peer-to-peer network and receiving, by the agent end-device from the authentication server, an instruction to register with the selected super-node server,
wherein the selected node is configured to receive from the authentication server an address of the recording system and to establish an auxiliary session with the recording system for reporting communication session events,
wherein the recording system is configured to determine that the communication session is to be recorded and to record the peer-to-peer communication session through the conference call.

6. The system of claim 5, wherein the communication session is one of a telephony session, an instant massaging session, a video session, a chat session, a web co-browsing session or a voice over Internet Protocol (VoIP) session.

7. A system for recording a communication session in a peer-to-peer communication network having one or more super node servers, the system comprising:
a selected super-node server;
an authentication server;
a recording system coupled to the selected super node server;
a target agent end-device; and
an automatic call distributor (ACD) system,
wherein the ACD system is configured to establish a peer-to-peer communication session between the target agent end-device and an external end-device over the peer-to-peer communication network via the selected super-node server and to implement the peer-to-peer communication session as a conference call such that the target agent end-device and the external end-device are respectively first and second participants in the conference call and to enter the recording system to the conference call as an additional participant;

wherein establishing the peer-to-peer communication session comprises receiving by the authentication server a request from the external end-device to register with the peer-to-peer network and receiving, by the agent end-device from the authentication server, an instruction to register with the selected super-node server,
wherein the selected node is configured to receive from the authentication server an address of the recording system and to establish an auxiliary session with the recording system for reporting communication session events,
wherein the recording system is configured to determine that the communication session is to be recorded and to record the peer-to-peer communication session through the conference call.

8. The system of claim 7, wherein the communication session is one of a telephony session, an instant massaging session, a video session, a chat session, a web co-browsing session or a voice over Internet Protocol (VoIP) session.

9. The method of claim 1, wherein entering the recording system to the conference call is done by the agent end-device.

10. The method of claim 1, wherein the recording system comprises an external node connected to the selected super-node server and an internal node, the method further comprises:
receiving media from the external end-device via the selected super-node on the external node of the recording system; and
sending the media from the internal node of the recording system to the agent end-device.

11. The method of claim 1, wherein establishing the peer-to-peer communication session further comprises:
