asterisk users - Sep 2004 - two asterisk boxes and using outgoing spool file on second box to call out on first box.

Hi All,

I am setting up two boxes with asterisk. Box A has a T100P.
It is working I can put calls in the outgoing spool directory
and call extensions or outside numbers and do a playback of
demo-congrats (not sexy but good for an example).

Now I have a second Box b. Box B has no hardware just
running asterisk. How do set the two boxes
so I can place calls in the outgoing spool on box B to route calls
through Box A?

What does that call file look like?
What other configurations do I need?

I tried putting a sip.conf defintion on Box A and doing a register
command in Box B in sip.conf but that is as far as I got.

Thanks,

Jerry Geis
