Hello,
Yes it is possible and cisco has a sample configuration for this scenario;
it's called "PPP Callback". Here's a sample configuration for IP.
Hub------ISDN------Remote
Hub Site:
----------
username Remote password 0 cisco
isdn switch-type basic-ni
!
int bri0
ip add 172.16.1.2 255.255.255.0
encap ppp
dialer-group 1
dialer callback accept ------------------ honor callback requests from
client
isdn spid1 21255512120101 5551212
isdn spid2 21255513130101 5551313
ppp callback-secure --------- (optional) authenticate client during
negotiations
dialer load-threshold 10 outbound
dialer map ip 172.16.1.1 name Remote class ccie broadcast 5551414
dialer map ip 172.16.1.1 name Remote class ccie broadcast 5551515
!
map-class dialer ccie
dialer callback-server username------- the "username" option tells the
router to reference the dialer map stmt. for the dial string and the
authenticated host name in order to call back the client.
!
dialer-list 1 protocol ip permit
Remote Site:
-------------
username Hub password 0 cisco
isdn switch-type basic-ni
!
int bri0
ip add 172.16.1.1 255.255.255.0
encap ppp
dialer-group 1
dialer callback request -------------- enable callback request by the client
to the callback server
isdn spid1 21255514140101 5551414
isdn spid2 21255515150101 5551515
dialer map ip 172.16.1.2 name Hub 5551212
ppp authentication chap
Note: The client will only dial the hub to let the hub know that it's
requesting a callback . The hub will then accept the request (if configured
to do so) and disconnect the call on behalf of the client and call the
client back.

Subject: Callback basic question
Hey all
I have a simple question which I was thinking about.
Suposse you have R1 and R2 connected with ISDN and you want only R1can
always originate a call to R2 but R2 made a callback to R1 . Is this
possible ?
