Someone already guessed/asked if this was a PM3... but if it is a modem,
we've had this happen on rare occasions (the caller would hang up but the
modem would continue to show CD and stay OH). It is usually a modem
problem, since it doesn't make sense for it to see Carrier when the
other guy has hung up (perhaps it is hearing itself somehow if the
switch has looped it someway?). It could also be a telco/modem problem
because isn't there a tone sent by the switch when the other end
hangs up and shouldn't the modem hear this?
The only modems I've seen this with are the cheaper ones... I don't believe
my Couriers have ever done this.
Later.
