Re: ISDN problem ! posted 12/14/2002

The problem appears to be with the calling router's  IP configuration. This
router immediately outputs a "IPCP: O CONFREQ [Closed]" to terminate the IP
session.

Too things to look at:
 - check the dial maps
 - check that dial-idle timeout

I could tell more with a config
