Abstract
A method and system for enforcing the user of a proxy server within an enterprise communication system. The system includes an enterprise voice application server configured to act as a SIP proxy to client devices, and a private branch exchange configured to act as a SIP registrar. The client devices are configured to evaluate incoming SIP requests to determine whether they were received via the enterprise voice application server and, if not, to respond with a SIP 305 Use Proxy message referencing the enterprise voice application server in a Contact field. The 305 Use Proxy message forces the PBX or other intermediate SIP server to reroute the SIP request and any subsequent SIP requests in the dialog through the enterprise voice application server.
