Usually one way audio is related to an IP routing issue.

     Greetings.  I'll start off by saying that I'm fairly new to CUCM.
I come from the Avaya world.  We've set up a test platform, running version 7.1.3.3.  The Gateway is a 2921.  It's talking to our
Avaya(5.2.1SP3) system over a QSIG trunk.

     I had calls traversing the trunk, sets from both sides could hear each other, CallerID information was sent.  I even managed to get integration with our AVST voicemail system working.  I was quite pleased with that given that we are dealing with three systems from different vendors.

     Sometime in the last few days, a one-way talk path appeared.  This only affects calls between the two PBXs.  Sets on the Avaya side cannot hear sets on the Cisco side.  I can hear myself in the earpeice of the Cisco phone.  Cisco sets can hear Avaya sets.  Calls from one Cisco set to another Cisco set work just fine.

     I've tried reseting the QSIG trunk from the Cisco and the Avaya end.  I also tried restarting the router that terminates the T1.
Nothing has worked.

     Any thoughts as to where to look?

     Thanks.

Chris...
