[App_rpt-users] Asterisk node without a radio?

[Phil N6TCT]

This may be a kind of offbeat question, but stick with me please.

I have an astrerisk/app_rpt node, we'll call it "node A", which is up
on a mountaintop, solar-powered, connected to a UHF repeater, and
behind a somewhat bandwidth limited IP connection.  The connection
will easily support one voice channel to the outside world, but not
many more than that with any reliability.

What I'd like to do is run another instance of asterisk/app_rpt on a
second machine that is on the Internet and that has good bandwidth and
CPU.  Call this "node B".  For echolink and allstarlink purposes, I'd
like there to be a "nailed up"/permalinked connection between nodes A
and B, but have people who want to use node A over the internet
instead connect only to node B.  The point being, if ten people are
connected to node B, node A only has to deal with one multiplexed
audio stream from node B, not 10 individual connections to node A --
all to conserve bandwidth to node A.

The catch is, node B isn't going to have a radio, it's just going to
be running asterisk/app_rpt for people to connect to.  In some sense,
it will be like an IRLP reflector (though obviously no IRLP is
involved here) -- it's basically acting as a radioless conference
bridge.

Any thoughts on how to do this?  Do I just run standard
asterisk/app_rpt and get an allstarlink/echolink node number but just
don't bother to define a radio channel or something?  Any ideas or
tips appreciated.

Thanks!
