1. A method for operating a communications system to handle a call, the method comprising:

  • receiving signaling for the call into a signaling processor;

    in the signaling processor, processing the signaling to select an identifier for routing the call;

    transferring a control message indicating the identifier from the signaling processor;

    receiving user communications for the call and the control message into an interworking unit;

    in the interworking unit, converting the user communications into asynchronous communications including the identifier in response to the control message;

    transferring the asynchronous communications from the interworking unit;

    in the interworking unit, monitoring the user communications during the call to detect a call trigger; and

    transferring a trigger message from the interworking unit if the call trigger is detected;

    receiving and processing the trigger message in the signaling processor; and

    transferring another control message from the signaling processor in response to processing the trigger message.
