I've seen something similar with a line that kept getting re-provisioned
from voice/data to just voice (3.5Khz instead of 64k clear channel).  I
yelled at the telco, he took a look at the line, and was like "That's not
right.  The first channel is 3.1Khz...  Let me fix that."  As soon as he
made the changes, their call came up.  Though I'm not sure if it was cause
code 081.

5.0B is the biggest bunch of crap.  We've had more problems with that
version of software than anything else.  Upgrade to the 5.1pX series just
to be safe.  We don't let a single pipeline leave the office here without
checking to make sure it's not running 5.0B.
