Abstract
A system and method to detect a call trigger during a call without requiring a service platform to remain connected to the call. A first communication device transmits a call having call signaling and user communications. A signaling processor receives the call signaling from the first communication device and selects a connection to a second communication device. An interworking unit receives the user communications from the first communication device and converts the user communications from a time division multiplex format to asynchronous transfer mode cells that identify a selected connection to the second communication device and transports the user communications to the second communication device. The interworking unit detects a call trigger in the user communications. The interworking unit transmits call trigger data to the signaling processor. The signaling processor processes the call trigger data and, upon validating the call trigger, instructs the interworking unit to transport the user communications to a third communication device. In response thereto, the interworking unit converts the user communications to asynchronous transfer mode cells that identify the selected…
