If your not showing any PPP debug information at all you may need to enable local authentication on your routers. A sample of the basic AAA commands are:
aaa new-model
aaa authentication login default local
aaa authentication login NO_AUTHEN none
aaa authentication ppp default local
A sample config for setting this up is at:

Hope it helps.

If this router is accepting the call, not sure about the reason for Async interface tied to dialer interface using dialer profile..Pl. remove the interface dialer 1 by using follwing command
conf t
no int dialer1
int async65
no dialer pool-member 1
Now configure the interface async65 for following
interface Async65
ip address 192.168.1.1 255.255.255.0
dialer in-band
encapsulation ppp
dialer string xxxxxxxx
dialer-group 1
async default routing
async mode interactive
After the turn on following debug
debug modem
debug ppp nego
debug ppp authentication

Ensure that the remote end is configured identically (async interface, PPP, w/ autoselect under the line). If it is, then you should reverse telnet to AS65, dial out manually, and see if you get the remote router prompt. If you connect but see no prompt, you may want to check the modem configuration. You may also want to try the same test from the other end.
