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.
