Halfway there. If the PRI code has problems then you this will effect the
modems too. One of the things that I noticed when I upgraded to ComOS 3.8
is that my 33.6 USR started dropping connections and it didn't drop once
in 6 months under ComOS 3.7.2c3. Increasing the delay between loss of DTR
and hanging up fixed the issue and I haven't been dropped since.
Because I don't write ComOS I'm completely guessing here, but I'd say that
problems in the PRI code maybe causing "glitches" which the modem is
interpretting as DTR dropping and hence terminating the call.

I'd really love it to be my telco, but...
