I want to configure asyn callback in router 2511. IOS version is 12.0(10). Clients are Windows 9x/NT.

I call the RAS and get authentication, after router received callback number from client, the call hang up but there isnt callback. The router cannot initiate callback function properly.
Here is the debug:
As1 MCB: Initiate Callback for callback at 0913214108 using Async
As1 MCB: Async-callback failed
TTY1: DSR was dropped

Any one help me, please
-----------
The configuration is below:

I debug some output:

General OS:

PPP authentication debugging is on
PPP protocol negotiation debugging is on
Chat scripts activity debugging is on
Callback activity debugging is on

And the result is:

session-timeout 5
autoselect during-login
script startup startModem
script modem-off-hook offhook

I would try a few things... the dialer is failing on the dial out.. the debug looks good up to that point. See the link below for details..

Dump the scripts for troubleshooting. I have over 300 routers on POTs line dialback and none use session-timeout, autoselect, script startup startmodem and script modem-off-hook. Remove each script and try it.. I am suspecting that the problem very well might be a script.
