|Description:||If I use a SIP-Provider who sends a "SIP/2.0 180 Ringing" all is fine!|
If I use a SIP-Provider who DOESN'T send a "SIP/2.0 180 Ringing" the call answers immediately but i have no audio. the other side rings and if they answers the call there is also no audio, if the hangup i receive the hangup command normaly.
Note from Walter below: this appears to be a problem with chan_dahdi not receiving a notification it needs if a 180 Ringing isn't sent to the bridged SIP channel.

What you've attached is a SIP trace, which is useful, but is not what we requested - an Asterisk DEBUG log. Please attach a DEBUG log illustrating the problem.

I looked into this a couple of minutes a while ago: it looked like the dahdi did not get into the right state without some ringing notification. This would make the subject somewhat misleading: quick guess says it's a dahdi problem (or a core problem).

Are you still experiencing this problem in a supported version of Asterisk?
