Ok, I have gotten my media proxy to work fine between sip to sip calls, but I seem to have problems when I am forwarding a call to the PSTN. I am sure I just have something in the wrong order, any pointers? Earlier in the ser.cfg if (method=="INVITE" || method=="ACK") { log(1, "[SER]: Loose Route detected, using MediaProxy\n$ use_media_proxy(); }; Forwarding section..... rewritehostport("PSTNGATEWAY:5060"); forward(uri:host, uri:port); break; The speed of time is one-second per second.
