[cisco-voip] Delay issues with CUCM862a Can someone point me in the right direction ??

[Gregory Wenzel]

I've just started troubleshooting these issues for a client whom I upgraded from ccm4.x to cucm8.6.2a.
They claim the problem did not exist when ccm4.x was in production.
Can someone tell me which traces are best to tblshoot kind of issue, kick me in the right direction before I start RTMT on cucm and debug on the gateways.
The problem is not system wide and only occur in this one particular building.

Complaints
Delay in answering calls in Bldg 1
Delay in transferring call in Bldg 1
Problems started immediately after the upgrade but they are telling me now 4 months later
IP Comm - Web interface is slow Sometimes when making a call you do not hear the ring tone


Variables
Switches used  "EXTREME" brand non-Cisco and I do not have access to these switches either
No network changes occurred since the upgrade that the customer wants to admit to.
Has its own subscriber in bldg 1
Every other phone in the 2K phone sized network all register to the same subscriber do not have this issue
It uses a 2811 gateway running 12.4.24T that is on the other end of a 1 gig fiber link across the street and I have no access to the devices that connect the two building together.



What major differences between signaling with version ccm4 and cucm862a would cause this?
I'm looking through the bug finder now. I would love to tell the client it's their Extreme switches but why then would it work on the old windows version.

Maybe it didn't work and the problem just go more pronounced after the upgrade.


I'm just looking for someone to point me in the right direction...:)

TIA
