Hi,
The 'dialer callback-server dial-string' allows the callback client to
specify the number on which it should called back during the initial call
in.
So, for example, the client calls in and says,'I am requesting callback, and
please call me back on 555555'.
Assuming the server is correctly configured for callback and the above
command is used, the server will 'say' (!),'Fine. I will call you back on
555555', and then attempt to do so.
(Ooooh dear...talking routers...I really am going mad!!)
Hope that helps,
Mark
