[cisco-voip] CCM6 MOH

[Ryan Ratliff]

Well the first part of troubleshooting one-way or no-way audio is to
establish if you are even receiving audio packets.  You could be receiving
packets and thus not have a routing issue only there is nothing but silence
in the audio packets you are receiving.  It's an important differentiation
but I'd guess either way your IPVMSA is doing something funky.

One way audio I would troubleshoot as a routing issue... However, MOH does,
in fact, work for a few seconds... and if you get put on hold in that
window, you hear music indefinitely.

However, if you are put on hold after that 5 seconds, you hear nothing.... I
have even tried this with the same call... reset IPVMSA, get MOH, after a
minute, resume and place on hold again, and they get dead air...

This is really strange, and the IPVMSA service is still running.
