I recently signed up for incoming VoIP provider.
Now when a call comes in Asterisk can answer it and send the call to another extension using the Dial Application. However when asking the user to input the extension of his choice i get dead air and following error.
Feb 17 13:44:57 NOTICE: rtp.c:289 process_rfc3389: RFC3389 support incomplete. Turn off on client if possible
– Timeout on SIP/188.8.131.52-f6e2e588
However, if I turn on SIP-Debug I can then dial the ext of my choice however turning that on breaks other things.
Any idea what the above error means and how i can fix it.
