I have been going back and forth with the service provider. We have a PRI handling off net calls which gets roughly 1 slip and 1 sec error every 30 seconds. This is causing echo and dropped calls. Attached is a copy of the PRI config any ideas would be greatly appreciated.
controller T1 0/0/0
framing esf
linecode b8zs
Clock source line
pri-group timeslots 1-24 service mgcp
description POTS T1

Do you have the following commands on your router:
network-clock-participate wic 0
network-clock-select 1 T1 0/0/0

I currently see a whole slew of time slips as well, but wasn't sure it was because I was crossconnected from a 1MFT-T1/E1 on a 3845 to a 6608 port. It works and there doesn't see to be any issues.
I don't have the network-clock-select statement, but I'm wondering which one I choose and will the "ccm-manager config" statement overwrite this?
It seems like a crapshoot, i.e. no documentation, on which things are overwritten with the "ccm-manager config" statement.
I'll be eventually connecting this to a PSTN in the next few weeks and would like to fix this sooner than later.

Ive tried to enter those commands both the will not work on our 2611

They are global-config commands by the way....just in case you tried entering them on the T1 controller.

Thanks Chris you where right I was trying to enter the commands on the controller. I'm going to monitor the controller and update the forum. What do these commands do?

They allow the card to partiicpate in clocking off of the network, and allow you to select the clocking priority.

Chris,
Since I have added the commands you requested there have been no I repeat not a single slip. I'm going to have to explain to magnt the function of the two commands and suggest the be used in future employments.
network-clock-participate wic 0
network-clock-select 1 T1 0/0/0
