---------------------------------------------------------------------- 
We just started having this problem after the server was fine for a few
months.  A recent software upgrade was done on it, so it could be related. 
It happened a week ago on one server, so I just moved the T1 cables over to
an identical server (spare) in case it was a hardware issue.

It happened again last night at 03:44:55 (see log file).

I have attached a full debug of the latest occurence.

We are using a te411p without the echo cancellation module.

The versions of software I am running are:

asterisk version: 1.4.30
dahdi version:    2.3.0
libpri version:   1.4.11
Debian:           2.6.26-2-686
