Hello Jiri, Wow ... voicemail is working now: TNX ! I can ear "something" with my Xlite client but voice is pretty distorted, I suppose that I have to convert the default announcement to another sample rate/frequency/codec. Unfortunately nothing is recorded, here is a trascript of voicemail session, any help will be appreciated ... 200 OK 58383:45571714 00000BD46BBF2446 Contact: <sip:300001@interconnessioni.it:5090> Content-Type: application/sdp . v=0 o=username 0 0 IN IP4 127.0.0.1 s=session c=IN IP4 127.0.0.1 t=0 0 m=audio 30410 RTP/AVP 3 a=rtpmap:3 gsm/8000 .
