IOS upgraded on 3640 router keeps incoming ISDN connections up.

We have just upgraded a 3640 to 12.2(2)T and noticed that all incoming connections to the PRI are staying up 24/7. When doing showing ISDN active, it states "Seconds Left" as unavailable.

Nothing else has changed aside from the IOS upgrade. The majority of routers dialling in are 1600's and a few 2500's. Is it a feature with this IOS ?

Re: IOS upgraded on 3640 router keeps incoming ISDN connections

Need to take a look on "sh users" and "sh isdn status" and see the users are still connected and the b channels are still active..also need to take a look on the running config..

Now if you want to disconnect the incoming connectioin if the line is idle from for some amount of time, you can configure idle-timeout..Here is the url for that..
