TA912 SIP binding to a Metaswitch- PRI out of 912 to customer phone system-
We are getting one way audio when we(315-328-9999) call them(315-265-4065), I can her them, but they (customer with 912) cannot hear me. I ran a voice verbose and sip stack verbose debug which is attached and the config is attached as well.
We have the same unit, configured the exact same way at another customer site, also a metaswitch SIP binding that is not having the issue.
Any help would be greatly appreciated.
Please let us know if you were able to solve this issue. If not, we will need to see the output of the following debug commands to start.
debug sip stack message
debug voice verbose
debug isdn L2-formatted
We may also need to see a packet capture to verify bidirectional RTP.
I'm going to mark this post as assumed answered, but if you are still having problems or wish to update this post, please do so. We would be glad to help!
Thanks David, and sorry for not updating...yes, this is resolved. It was a misconfiguration on our Calix edge gear (for the voice VLAN) that the Adtran is connected to.
It would be great if you could clue us in to WHAT was misconfigured for those of us who are having similar problems...
