I'm trying to get callback working on a 2611 router. Everything seems to work fine until the router tries to initiate the callback. The router times out trying to connect to a remote host, which i'm guessing is the modem. Here's the configuration I'm using:
version 12.2
no parser cache
service timestamps debug uptime
service timestamps log uptime
no service password-encryption
service compress-config

Any help or suggestions would be greatly appreciated.

George,
it seems that You are missing a line
modem autoconfigure discovery
under line aux0 configuration, also try to add the following commands under line aux0:
no flush-at-activation
no exec
transport preferred none
transport output none
autohangup
I have this working exactly as You described
If that does not help, I will need output of command debug confmodem posted here

Here is the url which has sample config and troubleshooting for "Configuring MS Callback Between a Router and a Windows PC"
http://www.cisco.com/warp/public/793/access_dial/async_ppp.html
Pl. see if that helps.
For config change, add "login local" under the "line aux 0" and I would modify your all chat scripts for 60 secs for timeout as 30 secs it little short time. So callback chat will look like
chat-script callback ABORT ERROR ABORT BUSY "" "ATZ" OK "ATDT \T" TIMEOUT 60 CONNECT \c
You can send those debug here for review.
debug chat
debug modem
debug ppp nego
debug aaa authorization
debug callbcak
debug ppp cbcp
