> 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.
