[arm-allstar] BBB/Pi or RTCM

Consider the RTCM to be an ip phone. It will only talk to itself without a
pbx.  Allstar is rhe pbx.

The RTCM is a stupid controller without a connected server

Doesn't matter where or what allstar is running on, as long as one the
sites with the RTCM is located on the same physical switch as the allstar
server. That allows for proper GPS timing between the allstar server and
the master RTCM.   In some cases people don't run any radios on this single
RTCM.

I use a bbb located at one of my sites and run a simulcast 900 repeater.
Work wonderful

Does that help?
