Abstract: An initial request is received to establish a communication session. The initial request contains a communication address of a first communication device. A communication server detects that the communication session cannot be established across a primary network. In response, the initial request is repurposed by changing the first communication address to a second communication address. The changed request is sent to a communication system, which adds a field to the changed request that indicates that the changed request is to be sent via a secondary network. The changed request is sent with the field to the communication server. The changed request with the second communication address is sent to a gateway to establish the communication session across a secondary network. A portion of the communication session is established using the second communication address. The first communication address is sent in the portion of the communication session using Dual-Tone-Multi-Frequency (DTMF).

Abstract: In one embodiment, an enterprise network is provided that includes a mobility agent 150 associated with a switch/server 100 or 104. The mobility agent creates a visitor application record 172 associated with a second communication device 140b. The visitor application record is associated with a first subscriber. A second subscriber is normally associated with the second communication device, and the first subscriber with a first communication device 136a. In response to creating the visitor application record, the native communication device record is associated with a virtual communication device having the same public and/or private numbers as the second communication device 140b.
