[Asterisk-Users] T100P / ZAP / PRI errors

Mike-

Do you have access to any kind of PRI test set, like a T-Bird or something.

A red alarm would be easy to capture I imagine - it would be nice to confirm
that it's a problem particular to your site.  The reason I mention software
is that I've noticed a lot of other messages regarding these spurious alarms
that immediately clear.  I've noticed changes in the code having to do with
the timing source.

But maybe you're right about the telco doing something odd!

Cheers
Scott

I have been seeing this for over a month, and blaming it on our generally
incompetent telco, so it's definately not a new issue.
