IOS router & SIP proxy server

I am trying to make VoIP call with sip between two IOS router running 12.2(15)T H.323 plus feature. When I try to make call through the SIP proxy server, it fail. The problem is how can I register the prefix my router user agent responsible for to the SIP proxy server. There seem no such command to do so in the IOS document.

When the sip voip call is between the two router directly, it work.
