Abstract
A transcoder of a communication system is arranged to selectively embed (104) a data pattern into a call (102) to produce a slow-rate data channel in the call emanating from a switch. The data pattern includes a call identity that uniquely identifies how the call is routed through the communication system. In the event that transcoder detects (106) this call identity during subsequent routing of the call back to the switch, the transcoder identifies that the call can be routed directly through the switch and therefore instructs (112) the communication system to execute a local routing operation in which control information is routed throughout the communication system while traffic information generated in the call is routed directly through the switch, as illustrated in FIG. 4.
