Ok no one seemed too interested in this problem (shrug) but to those who read it
when using multilink and callback and you do a
sho int dialer 0
Dialer0 is up, line protocol is up (spoofing)
(extra lines removed)
Time to interface disconnect: idle 00:04:07
if you do a sho isdn act you see
(all ph numbers changed)

I still dont know why this Unavail appears ! BUT in my case I found that W2K send ICMP to the global catalog server (apparently) I had enabled icmp on the interesting traffic list for testing purposes. This was reseting the idle timer, I mistakenly linked the problem to multilink.
So the idle timer was working, its just not displayed correctly. So if you ever see unavail - just do a show int dialer 1 and you will see the idle timer there !
By the way can we all not talk about Testking anymore -
its stopping people concentrating on the real issues of studing !
(please dont respond to that thought!)
Thanks

Subject: ISDN Multilink - ppp callback
I have experiencing a strange problem with multilink and callback, My issue is that the call isnt being droped when the idle timer expires, well to tell the truth I dont even see the idle timer !
My first question is why do I see 'Unavail', My second question is why doesnt the line drop (my thinking was that the idle timer isnt expiring). Anybody seen anything like this before ?
When I don't use multilink I DO see the timers and all behaves normally.
============================================================================================================
SOHO router (803) calling a Central Site (3640) with multilink and callback enabled (both sides)
after the call and callback occur I get
on the SOHO
