[arm-allstar] Reverse Autopatch

[David McAnally]

This might help.  It's kind of what I use for an incoming IAX2 voip
connection. The voip details are in iax.conf. As noted below, the context
in the iax.conf stanza points to this entry in extensions.conf. I used VOX
for a while, but have gone back to PTT via DTMF (*99=PTT and #=unkey).  For
VOX, change "|P|" to "|Pv|" in the rpt function.
