1. A system, comprising:
- a processor; and
a memory device, the memory device storing instructions, the instructions when executed causing the processor to perform operations, the operations comprising;
receiving a request for a call, the request identifying an origination address and a destination address;
sending a message to the destination address, the message requesting a protocol supported by a device receiving the call;
receiving a response from the device, the response identifying the protocol;
generating a modified request for the call according to the protocol identified in the response; and
routing the modified request for the call to a session control unit of an Internet protocol multimedia subsystem network.

Abstract
An Internet protocol Multimedia Subsystem (IMS) gateway application server includes an originating application server module adapted to invoke call control services in response to requests initiated by a voice over Internet Protocol (IP) (VoIP) client associated with a communication device such as an IP telephone. Disclosed gateway application servers include a proxy server module adapted to notify the communication client of session control messages intended for the communication device.
