ABSTRACT:
A system for providing a single number reachability solution for communications with a desktop telephone and a cellular telephone includes a mobility application coupled to a call management application. The call management application can associate a telephone number with a desktop telephone and a first communication port, receive a first telephone call initiated by a remote device and directed to the telephone number, and offer the first telephone call to the desktop telephone and to the first communication port. The mobility application can associate the first communication port with a cellular telephone, obtain a second communication port from multiple available communication ports in response to the offer, and place a second telephone call to the cellular telephone using the second communication port. Signaling associated with a communication session with the remote device passes through a call management application, and media associated with the communication session passes directly between the remote device and an answering device.
