I have a split T1 which now can't make or get calls with outside world. Inside network calls between sites work fine. We recently moved locations but have been running fine for a few weeks.
sh controller t1 0/2/1 shows ever increasing slip errors and I'm thinking that might have something to do with it but it's midnight and I can't see straight!
I've read about some folks ned to contact their provider to verify clock source needs but I'm not sure if that is truly my problem as we WERE running fine with all calls for weeks. Any attempt to dila into or our of the office results in busy signals.
I can provide any config results which may be requested... please help!
