Since this happens infrequent. Tell me how, and I will capture the
information. It is happening about 10 times or less per day. I am now
manually processing a script that takes the information in the calls table
by NAS, telnets into the NAS, and confirms the user is still active. If
there is a difference it will reset the port in the telnet session twice.
It finds less than 10 per day in my environment of about 30,000 calls.

If you change the hunt sequence from least used and round robin in the
terminal server to straight line, and fixed assignment you should never see
this problem. In one POP that is the only way that I could get the lines
provisioned, and I have never had a problem there. Reason the port the
user is disconnected from is immediately reassigned another user on the
next call. The natural disadvantage is that if/when you have a problem
such as a modem gets hung, the entire hunt group is held up with that one
call. It is much easier to find a problem and correct it this way, vs a
single modem in a 500 group pool having a problem, then once every several
hundred calls you have a problem.
