[cisco-voip] CMM-ACT Transcoding - DSP locked active

[Matthew Linsemier]

Hey all,

I¹m running into a weird issue. I have two CMM-ACT modules configured
identically across two 6509 switches registered to two UCM 7.0.2.21010-2
servers (latest ES, pub and sub).  All of the needed items are configured
(Media Groups, Media Group Lists, etc.).  For some reason on the second
CMM-ACT, the xcoder seems to be full of connections, even though I shut down
both the profile as well as SCCP.  Users will get a fast busy if the profile
is in no shutdown mode and SCCP is enabled (even though there are free
resources on the other xcoder CMM-ACT).

Total: 32

We¹ve never had much trouble with these before so I am trying to determine
if its a IOS issue (we are running 12.4(15)T9 or a new issue with the newer
UCM ES.  I suspect that if I restart the CMM, that the problem may resolve
itself.  The other DSP¹s registered with CallManager (conference and MTP)
work just fine.  The question is when will it crop up again.

I would prefer to run 12.4(25)MD on the voice gateways, but there seems to
be a bug with g729 phones placing calls as all you get is dead air.
Downgrading to 12.4(22) or 12.4(15)T9 fixes that issue.

Anyone seen anything like this before.

Matt
