Modem line doesn't always disconnect when link drops, have to manually clear the line.

Configured DDR via internal MICA modems on a 3640. Occasionally when the link drops the modem line doesn't go back to IDLE status and I have to use the "clear line 29" command.

How can I solve this?

Re: Modem line doesn't always disconnect when link drops, have t

Ensure that you are running the

latest modem code (2.7.3.0), and that

your IOS is recent (say 12.1).

You could then have a look at "debug modem"

during a call disconnect to see what is

different in the case when the modem does

NOT go back to the IDLE state, versus

when it does.
