I have a P2P T1 between 2 locations, Mitel SX2000 for the A-end, SX200 is Z-end. Using channels 19-24 for digital E&M. When circuit is up direct from CSU to PBX, all is well. When Cisco 1841s are placed at both ends, the voice circuits lock-up after a few minutes (data flow is fine).

Clock source is primary on the A-end, internal on the Z-end.

Does anyone have other sample IOS configs I might compare to? Thanks!
