T1 Contollers on MGCP 3945 gateway accumulating Slip errors. We have three PRI's inbound/outbound with the first set at clock source line primary. We are experiencing problems with faxes not completed. Fax machine's report line error and disconnect. I think its a clocking issue but haven't had any luck. Any suggestions

If you have slip errors, it is definitely related to clocking.
You must configure network-clock-participate and network-clock-select commands.
Here are some references:

do network-clock-select 1 T1 0/0/0 and it will fix it...
