I'm using stable, and first of all tried the built-in chan_h323. It compiled ok, but when I tried to get two Asterisk boxes to talk to each other using H.323, they could set up calls but not pass any audio. So then I moved on to chan_oh323 v0.6.5 with the Janus patch 4 releases of openh323 (1.13.5.3) and pwlib (1.6.6.3). This performs mostly OK, but I do have an issue with intermittent audio flutter on the output stream, which I think is due to spurious repeated packets. I'm still trying to get to the bottom of that (see my other posts on this list). If I can resolve that, then I would recommend chan_oh323. There are two other H.323 implementations for Asterisk (ooh323 and chan_woomera), but they both require CVS-HEAD instead of stable :-( I'll try them out when HEAD stops being so much of a moving target. At the very least, you should make sure you can get two Asterisk boxes to talk to each other properly using H.323 before you try talking to the upstream provider. Also, you will need to get your upstream provider to disable VAD (Silence suppression) in the streams it sends you.
