Really? I’m the only person on the entire Internet to get this message from an Avaya Session Manager?

481 Call Does Not Exist (no local tag match)

I’m trying to integrate Avaya Aura Session Manager 6.1 with an Audiocodes MP-118. I have it working in one direction so far. If all goes as planned, I’ll get this figured out and will forget all about the cause for this error 481. Alas, I look forward to it already.

UPDATE: This turned out to be sort of an asymmetric route. In the chaos and confusion of the moment, I had Session Manager A sending calls to the Audiocodes, but the Audiocodes sending responses back to Session Manager B. Hopefully this helps someone out there.
