System and method for processing a call

摘要

A signaling processor receives signaling for a user communication and processes the signaling to select a first packet communication path and a second packet communication path. The signaling processor transfers messages indicating a TDM communication path, the first packet communication path, and the second packet communication path. An interworking unit interworks the user communication between the TDM communication path and the first packet communication path. A communication device routes the user communication from the first packet communication path to the second packet communication path.
