Folks, please. I started this post, not because I necessarily felt there was a direct problem in FPBX, but possibly a bug in the way it was configuring Asterisk - I'll admit, I felt it somewhat annoying that the first thing that was called into question was some simple customizations around RTP port ranges, but I understand the troubleshooting process and how sometimes even the simplest (and unexpected) things can be the cause.
However, I'd like to share something I discovered earlier this week. Grandsteam has a HUGE bug in their G722 codec - specifically causing it's RTP timestamps to be all out of sequence (to the point the audio quality can easily become garbage). The 32xx phones were hit pretty hard by it, but so were newer firmwares on the 2130/40/60. Sure enough, testing an older 2140 (pre 1.0.4.x) worked fine with 722 calling into Asterisk, while the 32xx and current firmwares of the 2130/40/60 have this "dead air" issue.
Perhaps Asterisk or PJSIP interprets these as invalid data, causing no audio to flow. I don't know, but I don't believe it has anything to do with FPBX anymore, nor do I necessarily believe it's Asterisk directly (merely how Asterisk interacts with phones that may have an oddity in their 722 audio stream).
That being said, why doesn't everyone take a deep breath, go back to their corners, and think about why we're all really here. This is a great system, a wonderful project, and frankly something that the smart guys need to continue focusing on rather than feel attacked. I know when I get attacked repeatedly for doing really cool things, it lowers my drive - Not that that would happen in this case, but why even put those folks through that.

Thanks Andrew and Rob for at least digging into this - I know I tend to have a hard time seeing the difference between FPBX and Asterisk (as they're all bundled into a great package in my mind), but I very much appreciate your efforts in supporting my insanity.
