[Mac-telephony-list] Asterisk vs. OpenPBX

OpenPBX is a fork of Asterisk. It came about because some of the volunteer
coders were frustrated that Digium would not accept their patches. Digium is
quite picky about accepting patches or changes; they want to make sure
Asterisk is as stable as possible (I'm sure there is a personality aspect
there, too). OpenPBX allows these guys to scratch their itch unimpeded, but
changes in the Asterisk infrastructure later on can cause merging the two
codebases to be frighteningly problematic.
