I have configured Callback at my Access server, as follows:
---------------------------------------
!
chat-script offhook "" "ATH1" OK
chat-script callback ABORT ERROR ABORT BUSY "" "ATZ" OK "ATDT \T"
!
!
interface Group-Async1
ip unnumbered FastEthernet0/0
encapsulation ppp
async mode interactive
peer default ip address pool Async
ppp callback accept
ppp authentication chap pap callin
group-range 33 62
!
line 33 62
script modem-off-hook offhook
script callback callback
modem InOut
transport preferred none
autoselect during-login
autoselect ppp
callback forced-wait 5
!
-------------------------------------
When clients try to call the Access server with cllback permission at my AAA.. when dial the AS, verifying username and password and after that i configured the ACS to allow users to enter the telephone number that the AS will call. pop up window appears with waiting for callback and remain until timeout expired.
The debug messages "debug callback" show the following error "TTY60 Callback process fail - modemcheck status=10081".
Any idea?
Thanks in advance
