HiBenny, we got a problem with the SDP negotiaton. The logfile shows a call szenario where we get a first contact from an announcement server. After being forwarded we get a second SDP response from the real destination. Unfortunately this SDP is ignored! So the media could not flow. How can this be handled by pjsip?
