I have a SER Proxy that is routing calls to a SIP Redirector which then informs SER as to which gateway to send calls to.
GW1 GW2 | | SERProxy------->SIP Redirector | IP Phone
Just a thought, I havent experimented it though. You can have a work-around for this. Contact would still reflect SERProxy and will have gateway prefix like 001 for GW1 002 for GW2 ( Contact: <sip:001<number in orig uri>@SERProxy). This way IP Phone will call the new number on SERProxy and Proxy will send that to appropriate gateway based on prefix.
