We have a "dry pipe" between 2 of our remote locations.
We have a dual controller T1 card: WIC card on a 2811, as below.
Multi-Flex Trunk (Drop&Insert) WAN daughter card.
FRU Part Number VWIC-2MFT-T1-DI
We brought this router online to replace 3810, just yesterday.
We are seeing slips on the Voice T1.
We changed the clocing on the controller to "internal".
Slips are still incrementing, how can I overcome that.
Configuration is attached.

Two situations:
We're the clock master ( normally if we're connected to another PBX):
controller t1 0/0/0
clock source internal
We're the clock slave ( if we're connected to a provider, or a PBX that feeds us the clock):
network-clock-select 1 t1 0/0/0
controller t1 0/0/0
clock source line
Try adding the network-clock-select (global config) command for this T1.
