Yup, sorry for not clarifying.

I have pppd initiating a callback session (pppd v 2.3.11 with cbcp and
mschap patches), but I'm not dead sure how to handle the callback from the
RAS server. I've tried two things,

1. setting up mgetty to receive the callback and pass it to pppd

The problem with this is pppd doesn't seem to know what to do when it
answers the call. If I use 'auth', the calling back server won't
authenticate itself. If I use 'noauth', the calling back server sits there
without sending any LCP requests (so my pppd idles out).

2. running pppd a second time to handle the callback

I've tried running a second pppd to receive and handle the callback with a
chatscript like the following

ABORT VOICE
'' ATZ
RING ATA

But it doesn't seem to answer the modem when the callback down come.

So thats where I'm at .. any of this terrain look familiar to anyone out
there?

BTW If I don't try to use callback, it works grand without any hacking
(debian 2.2's pppconfig is a very neat little script).

Thanks,
