[arm-allstar] Remote Base BCD Channel Steering

[Ed Wilhelm]

Hi Doug,

Never did get a response. Was trying to avoid reinventing the wheel.

Never thought of using the patch command to do DTMF stuff. Will do some 
investigating.
That's the cool thing about Allstar/Asterisk, if you can think of 
something, there's usually a way to do it.

All your efforts are really appreciated.
