Another advantage of the technology is the immediate control of phone functions on the endpoint device and the direct connection with computer applications on the computing device, which emulate first party entry into the endpoint device, thereby increasing the effective uses of the VoIP call. Another advantage of the technology is the syncing of the call with the computing device prevents control data from being shown on the incorrect computing device if the actual call is not on the endpoint device connected to the computing device, thereby reducing call errors.
Another advantage of the technology is the direct connection between the VoIP endpoint device and the computing device increases the available uses of the VoIP control signaling without synchronization through an external service, thereby reducing the costs to deploy and utilize external applications with VoIP calls. Another advantage of the technology is the direct connection between the VoIP endpoint device and the computing device enables the transfer of the VoIP call information, thereby increasing the functionality of the shared VoIP call control through the shared use of VoIP call information.

DETAILED DESCRIPTION
The shared voice over internet protocol (VoIP) call control methods and apparatuses include technology that, generally, shares control of a VoIP call between a VoIP endpoint device (e.g., VoIP phone, VoIP software phone on a stand-alone device) and a computing device (e.g., a personal computer, a hand-held computer). The VoIP endpoint device and the computing device establish a direct connection (e.g., wired, wireless) between themselves to share the VoIP control signaling. The direct connection can be established without a relay between other devices (e.g., a VoIP server, a network router, a VoIP messaging server). The VoIP control signaling, generally, can include any type of information about the usage, establishment, control, and/or management of a telecommunication pathway (e.g., VoIP call pathway, VoIP to circuit switched call pathway) and/or telecommunication network (e.g., VoIP network, circuit switched network). The VoIP control signaling can include VoIP call information (e.g., caller identification, caller VoIP endpoint device identification, VoIP server information), VoIP headers (e.g., session initiation protocol (SIP) data, custom header), and/or any other information associated with the VoIP call (e.g., state change, agent registration, work mode, computer telephony integration (CTI) data).
For example, in operation, a user, via a VoIP phone, initiates a VoIP call with another user. The VoIP phone communicates with a VoIP server to initiate and establish the VoIP call with the other user, via the other user's phone (e.g., VoIP phone, a public switched telephone network (PSTN) phone). The VoIP phone establishes a direct connection with the user's personal computer. In this example, the VoIP phone is on the user's desk next to the personal computer and the VoIP phone and the personal computer are connected via a wired connection (e.g., universal serial bus (USB) connection, serial connection, parallel connection, Ethernet connection). The VoIP phone and the personal computer communicate VoIP control signaling (e.g., connection status, custom information about the call) between each other.
In this example, the VoIP phone communicates customer information using the VoIP control signals (e.g., customer information embedded in the VoIP control signals, customer information referenced in the VoIP control signals) and the computing device auto-populates the customer relationship application based on the customer information and/or customer information retrieved from a customer database. The personal computer can transmit VoIP control signaling (e.g., insertion of audio into the VoIP call, forwarding of VoIP call to another user) directly to the VoIP phone through the direct connection. The VoIP phone can modify the VoIP call based on the received VoIP control signaling. The communication of the VoIP control signaling via the direct connection advantageously enables the sharing of VoIP control signaling without the use of a relay (e.g., third party control server, a VoIP server), thereby decreasing the communication overhead (e.g., reduction in communication overhead, reduction in network latency, reduction in network congestion) and increasing the effective usage of the VoIP call (e.g., reduction in incorrect mappings between computing devices and endpoint devices, increase in call center operator efficiency).
As another example, in operation, a VoIP phone receives an inbound call from a VoIP server. The VoIP phone accepts the inbound call and establishes a direct connection with an associated computing device (e.g., a computing device designated by the user of the VoIP phone, a computing device designated in the inbound call). The VoIP phone transmits a VoIP control signal (e.g., a message that indicates that an inbound call from a particular person has been received, a packet with information about the inbound call) to the computing device.
In this example, an application (e.g., a customer relationship application, a customer repair application) operating on the computing device processes (e.g., extracts header information, retrieves customer account number from a database, retrieves customer information from a database based on header information) the VoIP control signal for the user to access the application. The user can modify the VoIP call utilizing the application (e.g., click on the insert standard audio button in the application, click on transfer to technical support button in the application). In this example, the user can insert audio into the VoIP call, via VoIP control signals transmitted to the VoIP phone, instructing the customer how to reset the customer's hardware device (e.g., phone, computing device). In some examples, the VoIP phone inserts the audio into the VoIP call. The direct connection of the VoIP control signals between the VoIP phone and the computing device advantageously enables the computing device to be involved in the call which decreases the call time and expenses related to the call.
FIG. 1 is a diagram of a shared VoIP call control environment 100. The environment 100 includes a computing device 120, a VoIP phone 125, a VoIP server 130, and a plurality of VoIP endpoint devices, a VoIP phone 151, a computing device 152 through a VoIP phone 159. A user 115 can utilize the computing device 120 and/or the VoIP phone 125 to control, via a direct connection 127, a VoIP call between the VoIP phone 125 and one or more of the other VoIP endpoint devices 151, 152 through 159. The user 115 can utilize user controls 123 within a graphical user interface (GUI) 121 (e.g., chrome extension, java applet, stand-alone application) on the computing device 120 to control the VoIP call. Users 161, 162 through 169 utilize the VoIP endpoint devices 151, 152 through 159, respectively, for calls with other users (e.g., each other, user 115).
The user 115 can control a VoIP call by communicating VoIP control signaling between the computing device 120 and the VoIP phone 125. For example, the VoIP phone 125 transmits call prompts (in this example, beeps between the caller's touch tone input) to the computing device 120. An audio insertion module (not shown) on the computing device 120 monitors the call prompts and inserts audio (in this example, an advertisement) into the VoIP call via the direct connection 127. The audio insertion module inserts the audio by transmitting the audio to the VoIP phone 125. The VoIP phone 125 inserts the audio into the VoIP call based on the VoIP control signaling received from the computer device 120.
Although FIG. 1 illustrates one VoIP phone 125 connected to the VoIP server 130, the environment 100 can include any number (e.g., ten, one hundred) and/or any configuration (e.g., stand-alone VoIP phone, software-based VoIP on a handheld computing device) of VoIP phones connected, directly or indirectly, to the VoIP server. Although FIG. 1 illustrates the VoIP endpoint devices, the VoIP phone 151, the computing device 152 through the VoIP phone 159, the environment 100 can include any number (e.g., one thousand, ten thousand) and/or any configuration (e.g., connection with PSTN endpoint devices, an audio to text translation server) of endpoint devices.
FIG. 2 is a diagram of a call sharing process 200. The process 200 begins by a user 215 initiating (251) a VoIP call using a VoIP phone 225 (e.g., dials a number on the VoIP phone 225, enters in a speed dial code on the VoIP phone 225). In some examples, the user 215 initiates a VoIP call using a computing device 220 with a user interface. In this example, the user 215 can utilize an application (e.g., customer relationship management application to call a customer via a direct connection between the computing device 220 and the VoIP phone 225, call management application to initiate a call based on voice prompts from the user 215) to initiate the VoIP call.
The VoIP phone 225 establishes (252) the VoIP call based on the request from the user 215 to initiate the VoIP call by communicating with a VoIP server 230. The establishment of the VoIP call can include the setup of the VoIP call between the VoIP phone 225 and another VoIP endpoint device (e.g., setup of VoIP call utilizing SIP messages, setup of VoIP call utilizing the VoIP server as an internet protocol (IP) private branch exchange (PBX)). In some examples, the establishment of the VoIP call includes the connection with an endpoint device connected to a PSTN, a PBX, and/or any other type of non-VoIP network.
The computing device 220 and/or the VoIP phone 225 establish (253) a direct connection between each other. In some examples, the VoIP phone 225 establishes (253) the direct connection at the initiation of a VoIP call. In some examples, the computing device 220 establishes (253) the direct connection at the start-up of an application (e.g., customer management application, audio configuration application) operating on the computing device 220. In some examples, the computing device 220 can record the VoIP call utilizing an application operating on the computing device 220. In some examples, the computing device 220 can translate the VoIP call utilizing a translation application operating on the computing device 220.
The user 215 modifies (254) the VoIP call by utilizing the user interface on the computer device 220. For example, the user 215 selects a user control to insert an advertisement into the VoIP call via the user interface. As another example, the user 215 adjusts an audio setting for the VoIP call via the user interface.
The computing device 220 transmits (255) VoIP control signaling to the VoIP phone 225 to control the VoIP call. In some examples, the user's modification of the VoIP call is embedded into SIP signaling for the transmission to the VoIP phone 225. In this example, the computing device 220 generates the SIP signaling based on the user's modification. In some examples, the user's modification of the VoIP call is forwarded to the VoIP phone 225 without modification. In this example, the direct connection is a forwarding of information from the computing device 220 to the VoIP phone 225.
The VoIP phone 225 receives (256) the VoIP control signaling and modifies (257) the VoIP call based on the VoIP control signaling by communicating with the VoIP server 230. In some examples, the VoIP phone 225 processes the VoIP control signaling received from the computing device 220 to generate VoIP control signaling for transmission to the VoIP server 230. In some examples, the VoIP phone 225 forwards the VoIP control signaling received from the computing device 220 to the VoIP server 230. In some examples, the VoIP phone 225 modifies the VoIP call directly without communication with the VoIP server 230. In some examples, the VoIP phone 225 modifies the VoIP call by communicating with the other VoIP endpoint device without communication with the VoIP server 230. In some examples, the VoIP phone 235 modifies the VoIP directly, by communicating with the other VoIP endpoint device, and/or by communicating with the VoIP server 230.
FIG. 3 is a diagram of a VoIP endpoint device 310 (e.g., stand-alone hardware-based VoIP phone, separate software-based VoIP phone). The VoIP endpoint device 310 includes a control share module 311, a control signal module 312, a control modification module 313, a VoIP call module 314, a VoIP audio module 315, a VoIP initiation module 316, an input device 391, an output device 392, a display device 393, a processor 394, and a storage device 395. The input device 391, the output device 392, and the display device 393 are optional components of the VoIP endpoint device 310. The modules and devices described herein can, for example, utilize the processor 394 to execute computer executable instructions and/or the modules and devices described herein can, for example, include their own processor to execute computer executable instructions (e.g., an encryption processing unit, a field programmable gate array processing unit). It should be understood the VoIP endpoint device 310 can include, for example, other modules, devices, and/or processors known in the art and/or varieties of the illustrated modules, devices, and/or processors.
The control share module 311 establishes a direct connection between the VoIP endpoint device 310 and a computing device (e.g., the computing device 410 in FIG. 4) associated with the VoIP endpoint device 310. The direct connection can include a wired connection and/or a wireless connection (e.g., wifi, Bluetooth). For example, the direct connection is a cable operating the firewire protocol between the VoIP endpoint device 310 and the computing device. As another example, the direct connection is wifi connection between the VoIP endpoint device 310 with a USB cable to a wifi transceiver and the computing device with a built-in wifi transceiver.
In some examples, the direct connection is established without a relay through another device (e.g., VoIP server, external signaling server). The direct connection between the VoIP endpoint device 310 and the computing device advantageously enables the communication of information (in this example, VoIP control signaling) without the overhead of a separate protocol and translation as needed by another device. In other words, the direct connection increases the effective uses of the VoIP call by increasing the speed and amount of information communicated between the VoIP endpoint device 310 and the computing device, because of the decreased communication overhead (i.e., no network overhead) and direct communication path (i.e., no conflicts).
The control signal module 312 communicates, via the direct connection, VoIP control signaling between the VoIP endpoint device 310 and the computing device. In some examples, the control signal module 312 transmits, via the direct connection, the VoIP control signaling to the computing device. In some examples, the control signal module 312 receives from the computing device, via the direct connection, modifications of the VoIP control signaling. For example, the control signal module 313 transmits custom headers with agent work modes (e.g., high priority, active) from the VoIP endpoint device 310 to the computing device for use by an application operating on the computing device. In this example, the application operating on the computing device can utilize the agent work mode to enter an operational mode (e.g., only answer high priority calls, answer all calls).
The control modification module 313 modifies a VoIP call based on the VoIP control signaling. In some examples, the control modification module 413 modifies VoIP call parameters (e.g., increases buffer, receives call information), modifies audio in the VoIP call (e.g., removes audio, inserts audio), and/or modifies hardware parameters for the device (e.g., increases volume, decreases gain, changes network address, server configuration). For example, the control modification module 313 can transfer the VoIP call to another user based on information in the application operating on the computing device (in this example, transfer a customer's call and the customer information from billing support to hardware support automatically). As another example, the control modification module 313 can insert audio instructions on how to reset a hardware device based on a user's request for the instructions.
The VoIP call module 314 transmits the VoIP control signaling to a VoIP server. For example, the VoIP call module 314 translates the modifications of the VoIP call received from the computing device into a SIP message for communication to the VoIP server. The VoIP audio module 315 transmits audio of the VoIP call to another VoIP endpoint device. For example, the VoIP audio module 315 communicates the audio packets from the VoIP endpoint device 310 to the other VoIP endpoint device. The VoIP initiation module 316 establishes the VoIP call with a second VoIP endpoint device. The VoIP initiation module 316 can establish the VoIP call utilizing a VoIP serve and/or any other type of call initiation process (e.g., communication with a PBX, communication with PSTN).
The input device 391 receives information associated with the VoIP endpoint device 310 from a user (not shown) and/or another computing system (not shown). The input device 391 can include, for example, a keyboard and/or a scanner. The output device 392 outputs information associated with the VoIP endpoint device 310 (e.g., information to a printer (not shown), information to a speaker).
The display device 393 displays information associated with the VoIP endpoint device 310 (e.g., status information, configuration information, graphical representation). The processor 394 executes the operating system and/or any other computer executable instructions for the VoIP endpoint device 310 (e.g., executes applications).
The storage device 395 stores configuration information and/or call configuration. The storage device 395 can include a plurality of storage devices and/or the VoIP endpoint device 310 can include a plurality of storage devices (e.g., a call configuration storage device, an audio storage device). The storage device 395 can include, for example, long-term storage (e.g., a hard drive, a tape storage device, flash memory), short-term storage (e.g., a random access memory, a graphics memory), and/or any other type of computer readable storage.

The above-described systems and methods can be implemented in digital electronic circuitry, in computer hardware, firmware, and/or software. The implementation can be as a computer program product (i.e., a computer program tangibly embodied in an information carrier). The implementation can, for example, be in a machine-readable storage device, for execution by, or to control the operation of, data processing apparatus. The implementation can, for example, be a programmable processor, a computer, and/or multiple computers.
A computer program can be written in any form of programming language, including compiled and/or interpreted languages, and the computer program can be deployed in any form, including as a stand-alone program or as a subroutine, element, and/or other unit suitable for use in a computing environment. A computer program can be deployed to be executed on one computer or on multiple computers at one site.
