Re: ISDN Callback.

Looks like your missing the ppp callback accept on the server end.

You might want to try and ad the command dialer callback-secure. This
command ensures that the initial call is always disconnected at the
receiving end and that the return call is made only if the username is
configured for callback. If the username (hostname in the dialer map
command) is not configured for callback, the initial call stays up and no
return call is made.

Can't get ISDN callback to work.
The call goes through but the call back doesn't come.
Does anyone have a working config to post.

Here is what I have.
