[Asterisk-Users] Upgrading 1.0.9 to 1.2 beta

[Mojo with Horan & Company, LLC]

I'd just work on upgrading the zaptel portion, don't do asterisk until 
you're ready.  Swapping 1.0.9 for something in the 1.2.0 line went 
pretty painless for me, and asterisk couldn't care less as far as I can 
tell. I'm using 1.0.10 asterisk and 1.2.0rc2 zaptel.
