Hi

This is PPP callback not ISDN callback (there is a considerable difference)
and you don't have a dialer remote name under the calling party's dialer
interface.

See if that makes a difference

Thanks

Steve

Hi,

Why do you only have "dialer-remote name" on only one side of the ISDN link.
Would you not want this statement on both sides.

Also, when using PAP authentication, the router sends its own hostname and
shared password to its dial-peer and vice versa.

By specifying the remote-name in the "dialer-remote name" statement, is that
not more of a requirement for chap instead of chap.

Apart from that, I don't see any thing wrong with the config.

Once the calling router has made the initial call to the called router, do
you see an attempt from the called router to bring up the dialer interface?

Raj.

Hi List,

I'm triying to configure ISDN callback on
a single ISDN line connected to two routers.
It looks like the authentication passes OK,
but then nothing happened - no call back.
My configs:

Calling party:
!
hostname 2504-1
!
username 2503-2 password 0 cisco
!
interface BRI0
 no ip address
 encapsulation ppp
 no keepalive
 dialer pool-member 1
 isdn switch-type basic-net3
 isdn answer1 XXXX
 isdn answer2 XXXX
 cdapi buffers regular 0
 cdapi buffers raw 0
 cdapi buffers large 0
 no cdp enable
 ppp callback request
 ppp authentication pap
!
interface Dialer1
 ip address 192.168.120.21 255.255.255.248
 encapsulation ppp
 no keepalive
 dialer pool 1
 dialer idle-timeout 50
 dialer string YYYY
 dialer-group 1
 pulse-time 0
 ppp callback request
 ppp authentication pap
 ppp pap sent-username 2504-1 password 7 00071A150754
!
dialer-list 1 protocol ip permit
!
