Masood,
I'm using 12.0(9), 11.3(11a)T1, and 12.1(3). My routers are
4500M w/ 4bri(S/T), 2520, and a 1004.
I'm also using a teltone ILS2000 simulator. To date I've only noted
problems with IOS 12.0.15 which I don't use any more.
Another thought.. when you place the call which bri is in use on either side
of the circuit... (i.e bri0:1 or bri0:2)
Also check to make sure your not calling in on the same line of your
connected port.. (i.e your not calling your self...). "debug ppp authen "
should confirm this.
I've done this a couple of times.. simply used the wrong dialing
number....:-)
debug ip pack is ok... but the isdn specific debug commands helps
trouble-shoot and isolate the problem much more effectively.. Whenever I
set up isdn now I turn on "debug dialer pac" and "debug ppp auth"..
Nigel..
