Abstract:
A method of handling a telecommunications call, the method comprising:receiving an initial address message for the call in a call processor; receiving asynchronous communications for the call in a gateway wherein the asynchronous communications for the call include a first virtual identifier for routing the asynchronous communications; in the call processor, processing the initial address message to select a second virtual identifier for routing the asynchronous communications; transferring an instruction indicating the second virtual identifier from the call processor to the gateway; in the gateway, modifying the first virtual identifier in the asynchronous communications to the second virtual identifier; and transferring the asynchronous communications including the second virtual identifier from the gateway, wherein the call processor and the gateway are external to any asynchronous transfer mode switches, and wherein the gateway has a single input port for receiving the asynchronous communications and a single output port for transferring the asynchronous communications.
