RE: dialer profile and callback?

All,

I think we need to be careful here in defining ISDN CLI callback and pp
callback as they are both quite different beasts.

For ISDN callback we need to use: dialer caller .... callback
This is dependent on CLI presentation to the answering router. Without CLI
this will not work. Basically this causes the answering router to pattern
match against the number presented via CLI and if it matches hangs up the
call and calls the CLI number.

For ppp callback we use the dialer-map ip x.x.x.x name x class test etc
And we also define ppp callback accept
On remote ppp callback request

Under the class we define dialer callback-server username. Note we need some
form of auth (ie CHAP for this to work as we need to match the remote
username to a dialer-map.

I have some example below. Note I have left some config that is required off
such as dialer-lists, etc.

Firstly PPP callback on physical:

PPP Callback Server

Username test pass cisco
interface bri 0
 ip address 1.1.1.1 255.255.255.0
 encapsulation ppp
 dialer callback-secure
 dialer enable-timeout 2
 dialer map ip 1.1.1.2 name test2 class dial1 98765432
 dialer-group 1
 ppp callback accept
 ppp authentication chap
!
map-class dialer dial1
 dialer callback-server username

PPP Callback Client

Username test2 pass cisco
interface bri 0
 ip address 1.1.1.2 255.255.255.0
 encapsulation ppp
 dialer map ip 1.1.1.1 name test 12345678
 dialer-group 1
 ppp callback request
 ppp authentication chap

Now for ISDN Caller ID Callback we have more options:

This is using dialer profiles

Interface dialer 1
ip address 1.1.1.1 255.255.255.0
 encapsulation ppp
 dialer remote-name test
 dialer string 4156884540
 dialer pool 1
 dialer-group 1
!
interface bri 0
 encapsulation PPP
 dialer pool-member 1
 ppp authentication chap

This is on the physical int:

interface bri 0
 ip address 1.1.1.1 255.255.255.0
 encapsulation ppp
 isdn caller 81012345678902 callback
 dialer map ip 1.1.1.2 name test2 12345678
 dialer-group 1
 ppp authentication chap

                Under the dialer interface:

                dialer-caller xxxx callback (where xxxx is the dial
string)

                Just as frame-relay point-to-point subinterfaces do not need
frame-relay map
                statements, dialer profiles do not need dialer-maps.

                Configure the dialer interface the same as for any other
connection.

                Hi,

                How can you configure dialer callback inside a dialer
interface, in the
                usual
                way we do it by dialer map and we do a dialer class with
dialer
                callback-server username.

                So how can we do it inside the dialer virtual dialer
interface, it does not
                accept map statement!!
