Hi all, Just wanted to see if anybody is seeing similar issues. Issue: Our customer receives an inbound call from any of our sip peering partners. Our customer then initiates a hold. In the REINVTE our sdp contains a=sendonly. All of our carriers respond back with a BYE. This problem only occurs when the originating party is calling from comcast service from Utah and Washington State. It appears that comcast, in their 200OK, is not sending any direction attribute (not sending direction attribute = sending sendrecv) and because of this our sip providers terminate the call in both directions I've tried changing our hold configuration to use c=0.0.0.0 but I think our carriers overwrite this back to a=sendonly as the problem still occurs. Any thoughts... Peter Fabian | Senior Voice Engineer
