[arm-allstar] Repeater site ALLSTAR recovery after POWER FAIL

[Dave Petrie]

Hi Larry, how about hooking up a dtmf controlled relay to the repeater
receiver totally independent of anything, it is merely using the repeater
receiver as an audio input source so you can send dtmf command to the relay
and it will do as you command, cycle, turn off, turn on, and run the power
to the raspberry through the relay. You may not need this if you simply
delay the startup
of the raspberry as described below in rpt.conf.
IP should not come into the picture, one thing you could try is delay the
startup for say 2 minutes so that things settle down with the LAN and then
the raspberry loads the software.
here is the relay and the area in the /etc/asterisk/rpt.conf you change for
startup delay.

rpt.conf
A3=cmd,/usr/local/sbin/saypublicip.sh 40039 ; Say Public IP to radio,
replace my node 40039 with yours

; Macro to run at startup (optional)
startup_macro_delay=180 ;delay macro starting ? seconds so ethernet can
establish to other nodes
startup_macro = *A3 ;Say local Public IP to radio, add more commands
separated with , end with #
