ABSTRACT:
A telephony system includes a switch coupled to a call agent and a legacy application, and further coupled to resources, some controlled by the call agent and others controlled by the legacy application. The switch processes connection requests from the call agent and the legacy application, and, using a resource emulator as an intermediary, establishes connections between call agent controlled resources and legacy application controlled resources.
