ISDN call to never hang up?

[connie]

Hi All

Is there a way that you can configure a router not to hang up an ISDN call after a specific time period? We have an outdoor extension that we use for our ISDN connection - we don't pay for the phone calls - so I want the router to be online at all times...

You can configure idle timeout to max amount of seconds 2147483..So line will stay up for that many seconds even if no intersting traffic is passed accorss the link..But a single interesting packet will reset that timer back to maximum..Here is the link for config etc.
