1. A system, comprising:
- a processor; and
a memory storing instructions that when executed cause the processor to perform operations, the operations comprising;
receiving, at a gateway, a request for a call sent from a communications server, the request for the call identifying an origination address of the call; and
routing a modified request for the call from the gateway through a session control unit of an Internet protocol multimedia subsystem network to the origination address to determine whether a calling device supports a user agent Computer Supported Telecommunications Applications protocol.

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.
