Hello List, I have the following setup - kphoneA------------- [SER A] ---------------- [SER B] ---------- kphoneB I am forcing both SER A and B to use mediaproxy regardless of whether the UA's are natted or not (ser.cfg file attached). When kphoneA makes a call to kphoneB, use_media_proxy() works fine on SER A. But on SER B, it fails (I can see an error - mediaproxy: Call-Id not found - but ethereal traffic dump shows that the Call-Id is present in the SIP message). So I get a call between khponeA---serA---kphoneB. When I initiate the call from kphoneB, the whole thing reverses and it becomes kphoneB---serB----kphoneA. I am using ser-0.8.12 (cannot use cvs version at the moment due to some code changed we have done) and mediaproxy-1.0.1. Anyone got any clue where I am wrong? ser.cfg file attached. Any help will be greately appreciated.
