Hello everyone, I must use SER as a proxy server to send every request to SipXchange (except the MESSAGE request that will be handled by SER) Can I get some help on this?, Is there any example I could use as a reference?. The user must be registered in SipXchange (in SER it would be optional) If the request is "MESSAGE" then SER will handle the request. This is what I have done if (!method=="MESSAGE") { xlog("L_INFO","Foward process\n"); forward(SipXchangeServer,SipXchangeServerPort); break; } But I think something is missing, Kat.
