Still having problems here.  Today there was a red alarm on channels
1-24 (the T1 going out to the telco) and all calls were dropped.  This
has also happened several other times.  We've been using this T1
without the asterisk box for over a year now and this has never
happened before, and even now if I disconnect the asterisk box and run
the line straight into a channel bank it doesn't happen.  I've googled
and googled and can't figure it out.
