Hello, i like to use pjsip for a home-automation project, to give me a call, when something is wrong at home. Therefore i use a server, running Ubuntu 12.04 Server Edition, without any GUI. Installation of version 2.0.1 of pjsip went well, so no problem with that. But when i like to use a wav file (i use the wav-file generated by pjsystest), i get always the message *Bad RTP pt 8 (expecting 9)*, this comes up continuously until i stop that call. The phone on the other side is ringing, but there is no sound coming up. I am not an expert for sip, but i have checked all the relevant pages in Google, and can't get any real help. The sip registrar is a Router (AVM Fritzbox 7390) which is connected as DSL router to the internet. Attached is a log which maybe helpful. Could someone please point me into the right direction to fix this issue? Regards, Ruediger -------------- next part -------------- An HTML attachment was scrubbed...
