If you have Caller ID on your ISDN line, PPP can use the calling
number to identify the the callback requester. If you don't, PPP has
to use the "username" during authenication to identify who the
callback requester is and make the callback. I've done debug ISDN
q931 and seen the calling number come across even when I didn't have
caller ID enabled on my 2 ISDN lines. Still wouldn't work. I also
tested the "ISDN caller" commands which uses caller ID for call
screening, didn't work either even though I saw the calling number
come across in the debugs. I guess caller ID puts the the calling
number earlier in the negotiation than what I was seeing.
hope this helps
Tony

Subject: PPP CallBack configuration problem
When I config PPP CALLBACK WITH FOLLOWING MAP-CLASS
map-class dialer mycallback
dialer callback-server dial-string
IT DOESN'T WORK. Debug tell me that "no call back configured for
username r2"
if I use follwing map class
map-class dialer mycallback
dialer callback-server username
IT DOES WORK.
I wonder when and how to use "dialer callback-server dial-string".
Thanks.
