CUCM 6.1 calls dropping

[jeter]

Here's the skinny: There was an upgrade from 4.2 to 6.1 all seem to work okay until today. The customer called and advise that four of the five remotes (ccme) intermittently are droping calls from the Unity (call handler). So when a call comes in on the PRI Unity answers and the user presses off (dials one) you hear please wait while we transfer your call. If the call is good it connects right away. If the call is bad there is no audio and the end user disconnects. FYI Unitys TSP was upgraded. Any thougts?

how many ports on Unity? I had a sim prob and had several ports that needed to be restarted.

Hope this helps.

Further debuging shows when it fails that we get a cause code of 47 indicating a resourse problem. Looking into codec issues at this time..

Are your resources registered in cucm?
Also what version of Unity? Did you try and put the old TSP back or replace it?

We found that for some reason we had to rearrange our voice class codec. Were testing one site at a time in so far it looks ok...

As far a unity is concern we temporaly setup a DID to a remote site bypassing unity and we had the same issue. The TSP was upgraded before the upgrade.
