So you want FreePBX to be no better than any other Asterisk-based PBX project? That’s a low bar.
No, I’m not worrying about it at all. I was asked to give an example, and I gave one. If I spent hours combing through the Wiki, I would have listed 30 examples. I don’t have that kind of time.
The fact that Chan_sip isn’t being developed is totally irrelevant. FreePBX supports it, in that you can set-up and use Trunks with Chan_sip… Chan_sip works, and it works well. If it has bugs, I haven’t found any in years.
The reason that Digiium isn’t developing it is because it works and they’ve moved on. As long as Chan_sip is included in FreePBX, it should be documented by FreePBX.
The notion that we should not document any component that is no longer in active development, even if it is supported in FreePBX (meaning that you can use it, make, it work, etc.), is a horribly low bar.
Keep up that attitude and we’ll see FreePBX die a slow and painful death.
