How about this.
Set your ISDN router to *not* bring up on ICMP, but still to pass it if the
list *is* up.
Then just monitor the remote interface with an ICMP ping. If you get a
response, the line is up. If you get 'unreachable' or timeout, then it's
Then set a 'service notify' for the ping for 'recovery' (so you get notified
when the line comes up) and hook this to a user or dummy user with a pager
I had a similar problem (although not internationally) a few years back
caused by Netware 4 licensing key checks. Cost ukp10k.
