RELATED U.S. PATENT APPLICATION 
     This Non-Provisional US Application claims priority to Provisional U.S. Application 61/315,985, filed Mar. 22, 2010, which is incorporated in its entirety by reference herein. 
    
    
     FIELD OF THE INVENTION 
     The present disclosure generally relates to an apparatus and method for intermediately connecting a landline telephone call to a cellular telephone. More particularly, the present disclosure relates to a an apparatus that receives an inbound telephone call made to a landline and conferences the inbound call into an automated call forwarding to a cellular telephone. 
     BACKGROUND OF THE INVENTION 
     People always continue to pursue lower cost options for living expenses or operating costs. One focus is directed towards utility costs. These include power, water, and communications. Landline telephone services are offered charging fixed local calling rates and either fixed or toll-based long distance calling rates. The toll-based rates are based upon minutes (or partial minutes) of talk time, with additional considerations for international calls. Cellular telephone services are offered charging airtime based rates with considerations for specific call connections. The monthly service charge includes an allotment of airtime. Any overage is charged per minute (or partial minute) at a substantially higher rate. Any underutilization of the allotment is either applied to the customer&#39;s subsequent bill or simply lost. The customer needs to determine an optimal monthly utilization and base a contract on an allotment of airtime accordingly. 
     Cellular telephone service providers have offered unallocated airtime for specific connections. One exemplary credited airtime would include calls made between two cellular telephones associated with the same service provider. A second exemplary credited airtime would include calls between a previously established series of specific telephone numbers and the subscriber&#39;s cellular telephone. A third exemplary credited airtime would include calls between a landline having service provided by the subscriber&#39;s cellular telephone service provider and the subscriber&#39;s cellular telephone. 
     A caller is desirous of contacting an individual. The caller dials a telephone number to contact the individual. If the individual is not available at that telephone number, it is common for an answering system to record a message from the calling party. The caller can subsequently try another telephone number to try to attempt to contact the desired individual. This requires that the recipient disseminate their cellular telephone number. There are many reasons why this would be undesirable. 
     A recipient can opt to forward calls from a telephone number to their cellular telephone. This process redirects the inbound call to a new telephone number. The cellular subscriber would incur airtime charges in accordance with the calling parties telephone number. 
     Therefore, it would be desirable to have a device that increases the connectivity between an inbound call and the desired recipient, while reducing the monthly expenses respective to cellular telephone service.

For purposes of description herein, the terms “upper”, “lower”, “left”, “rear”, “right”, “front”, “vertical”, “horizontal”, and derivatives thereof shall relate to the invention as oriented in  FIG. 3 . Furthermore, there is no intention to be bound by any expressed or implied theory presented in the preceding technical field, background, brief summary or the following detailed description. It is also to be understood that the specific devices and processes illustrated in the attached drawings, and described in the following specification, are simply exemplary embodiments of the inventive concepts defined in the appended claims. Hence, specific dimensions and other physical characteristics relating to the embodiments disclosed herein are not to be considered as limiting, unless the claims expressly state otherwise. 
     An exemplary call processing method  100  is presented in  FIG. 1 , with a supporting exemplary call processing system  200  block diagram being shown in  FIG. 2 . The call processing method  100  initiates with an inbound call to a landline service  102 . The inbound call can be initiated from an inbound cellular telephone  220 , an inbound landline telephone  222 , an inbound fax machine  224 , and the like. It is understood that as technology advances other inbound call technology would be considered as inclusive. The inbound call is forwarded to a structure  210 . The signal is distributed to each of the recipient wall outlets  212  networked throughout the structure  210 . A call processing device  300  is connected to one of the recipient wall outlets  212 . The recipient wall outlets  212  are representative and can be considered as the telephony lines, a modem line (such as a cable modem, DSL, T-1, and the like), or any other communications interface. This would accommodate the use of telephony, Voice Over Internet Protocol (VOIP), and any other communications protocol. The inbound call is received by the call processing device  300  in accordance with an inbound call answering step  104 . The call processing device  300  can then optionally offer the inbound caller options  106 . The options can include passing through the processing device  110 , utilizing call processing device options  112 , or terminate the call  114 . Should the user elect to pass through the processing device  110 , the call would be continued to a structure recipient landline telephone  214 , an answering device, a fax machine, and the like. The call processing device  300  would listen in on the inbound call to determine if the inbound call is transmitting a fax tone, a Dual-tone multi-frequency signaling (DTMF) (commonly referred to as a touch tone signal), a voice transmission, and the like. The call processing device  300  would interpret the identified signals and respond accordingly. Should the call processing device  300  fail to detect an inbound signal, the call processing device  300  would terminate the inbound call  114  and reset into an on-hook condition. 
     The call processing device options  112  offer the inbound caller several options, including accessing a dial tone  120 , forwarding the inbound call to the recipient&#39;s cellular telephone  122 , continuing the connection through the landline or Internet  124 , or terminating the call  114 . The call processing device  300  offers the inbound caller the ability to access a dial tone  120 , allowing the inbound caller to dial a new number. The system could include programmable limitations, such as no long-distance dialing, no international dialing, and the like. The user would establish the criteria based upon the long-distance and international calling portions of their landline service agreement. This establishes limitations and controls imposed upon the inbound calling party. Should the inbound caller elect the option of forwarding the inbound call to the recipient&#39;s cellular telephone  122 , the call processing device  300  would dial a phone number to connect a call to a recipient&#39;s cellular telephone  232 . The inbound caller can elect to continue through the landline or Internet  124 . This option connects the inbound call with a recorder, voice mail, or similar associated with the respective telephone line of the structure  210 . This option could also be utilized to connect a fax machine, a modem, and the like. The inbound caller can manually request to terminate the call  114  or simply hang up. The call processing device  300  monitors the circuit to determine if one of the connections has disconnected. Upon identification of the disconnection, the call processing device  300  terminates the call. Intelligence can be included to disconnect only a portion of the connections. 
     The step of forwarding the inbound call to the recipient&#39;s cellular telephone  122  can be activated or deactivated by the user. The user can change the status of activation of the forwarding process by contacting a switch on the call processing device  300 , remotely accessing the call processing device  300  and entering a specific code, a command provided via an Internet webpage, a remote command transmitted via an email, a short message service (SMS) transmission, and the like. A preprogrammed window of time can be used as an alternate or secondary means of controlling the activation of the forwarding the inbound call to the recipient&#39;s cellular telephone  122 . 
     When forwarding the inbound call to the recipient&#39;s cellular telephone  122 , the inbound reference identifier used to identify and log the calling party is masked, as the connecting call utilizes the reference identifier of the call processing device  300 . The outbound call can be provided across a landline telephone network associated with the structure or a cellular telephone modem associated with the structure. In a first example, the reference identifier of the inbound cellular telephone  220  (ID:  1 ) is received by the call processing device  300 . The call processing device  300  in turn calls the recipient&#39;s cellular telephone  232  via a new connection using the reference identifier of the call processing device  300  (ID: 3 ). The call processing device  300  automatically connects to the recipient&#39;s cellular telephone  232  via a recipient cellular network  230 . The reference identifier for the call is ID: 3 , thus utilizing the airtime billing associated with reference identifier ID: 3 . The recipient (cellular subscriber) would configure their contract agreement with the cellular provider whereby airtime associated with all calls between the recipient&#39;s cellular telephone  232  and the call processing device  300  is free. At a point during the call, the call processing device  300  automatically conferences the inbound call from the inbound cellular telephone  220  to the connection substantiated between the call processing device  300  and the recipient&#39;s cellular telephone  232 . Conversely to forwarding the call that would utilize reference identifier ID: 1  with the call data record (CDR), the call processing device  300  generates call utilizing reference identifier ID: 3  to call back a device associated with the inbound call by dialing the inbound call reference ID. Similarly the call processing device  300  would mask the reference identifier ID: 2  of an inbound call from the inbound landline telephone  222  by conferencing the inbound call with a connection between the call processing device  300  and the recipient&#39;s cellular telephone  232  using reference identifier ID: 3 . This system allows the subscriber to receive and forward unlimited calls inbound to a specific number, and utilizes a single reference identifier for connecting the calls to the recipient&#39;s cellular telephone  232 . 
     An exemplary embodiment of the call processing device  300  is detailed in  FIG. 3 . The call processing device  300  is fabricated having a call processing device housing  310 . A printed circuit assembly  320  provides electrical circuitry (including a microprocessor and respective operational firmware), power regulation circuitry, signal connectors and system integration. A power support connector  322  is provided to receive power from an external power source. The power support connector  322  is one exemplary means for providing power to the printed circuit assembly  320 . Power can alternately be provided by a portable power source such as batteries; a green energy source such as solar power, a network power source such as a solar panel; and the like. The circuitry can include connections and respective drivers for any of a variety of interfaces, including at least one RJ 45 Ethernet connection  324 , at least one RJ 11 telephone connection  326 , and/or at least one Universal Serial Bus (USB) connection  328 . The printed circuit assembly  320  can include circuitry, respective software, and antennas  330  providing a wireless connection, such as a radio frequency (RF) connection, a cellular modem interface, a WiFi connection, ZigBee connection, and the like. The RJ 45 Ethernet connection  324  provides an interface for connectivity to a local wired network and other networked devices. A series of RJ 45 Ethernet connections  324  can be utilized as a network switch between devices. The devices can include a computer, a fax machine, a printer, a scanner, a Voice Over Internet Protocol (VOIP) telephone, a video phone, and the like. Alternately, a wireless connection can be provided to replace the wired connections. A series of RJ11 telephone connections  326  can be integrated providing connectivity between the call processing device  300  and a series of standard telephony devices, including telephones, answering machines, modems, fax machines, and the like. A series of RJ11 telephone connections  326  can be integrated providing connectivity between the call processing device  300  and a series of electronic devices. The RJ11 telephone connection  326  has become a common standard interface for communicating between electronic devices. It is understood that other interfaces can be integrated into the call processing device  300  as technology advances, and the terms would be inclusive of new technologies having equivalent functions as those disclosed herein. 
     The printed circuit assembly  320  includes software to monitor the status of each call connection. When the printed circuit assembly  320  determines a call connection is no longer valid, the printed circuit assembly  320  reverts to an on-hook status. When an incoming call is determined to remain connected to the network provided within the  210 , the call processing device  300  redirects the call into the network and maintains the respective status until another device engages with the call. Upon engagement, the printed circuit assembly  320  terminates the connection to the call processing device  300 , leaving the connection between the other device and the call in tact. 
     The system can alternately forward calls to a specific extension within a VOIP network. The VOIP network can accommodate nodes or extensions at remote locations via the Internet. The call processing device  300  would forward calls to the specific node. 
     Since many modifications, variations, and changes in detail can be made to the described preferred embodiments of the invention, it is intended that all matters in the foregoing description and shown in the accompanying drawings be interpreted as illustrative and not in a limiting sense. Thus, the scope of the invention should be determined by the appended claims and their legal equivalence.
