Andy,
These are my notes on this:
-There are 2 types of callbacks: ISDN callback & PPP callback. They are
both well documented in the IOS Dial Technology CG in a separate chapter on
Callback.
-ISDN callback is done based on the phone # of device initiating call. Use
isdn caller <#> callback. If the caller ID matches the # in command, rtr
will make a callback to that #. If callback must be based on username, then
ppp callback must be used.
If you don't get this work, would you post your config's (both sides), along
with debug dialer output.
HTH, Tim

Hi John,
i've tried to configure dialer profile for callback on server side, not with
ppp cmd but "dialer caller xxx callback" instead. Unfortunately it did not
work.
The debug dialer said the client side attempt to call, the server side
disconnect and starting to callback but... that's all. The isdn bri did not
come up.
So what's the problem here ?
TIA,
Andy.
