You can’t translate g729 without a license from Asterisk.

G.729 is a very old codec, low quality by modern standards. The vast majority of systems have no need for a compression codec. The only advantage of g729 is that many providers support it.
IMO, if you need a compression codec (because your bandwidth is very limited or expensive, or you have high packet loss), I recommend running the PBX in the cloud where it has good network connectivity, with Opus between your extensions and the PBX.
If you absolutely need g729, compile it yourself, for example http://asterisk.hosting.lv/
g729 works just fine but there is no translation path without a license. They are showing the translations paths.

@kgupta Is codec_g729a installed as part of the 17 packages?
It is.

IIRC, a free g729 codec has been included at least since FreePBX 16 with the oficial distro.
I have it working on FreePBX 17 and I didn’t need to do anything special to make it work.

If compiling the one mentioned here, make sure that you do not include any of the Intel code, only the slow, open source implementation. The Intel code is licensed for evaluation use only, not for production use, and its licence is therefore incompatible with the GPL.
When the Sangoma supplied codec was first written, G.729 was encumbered by patents, so they had to have a version written and it had to be paid for. They will not have the necessary licences, from its developer, to allow them to relicense as open source.

@BlazeStudios That’s not codec_g729a, that is just knowing the existence of g729 as something in the world.
@arielgrin Correct, as long as you have an activated system it should be available if codec_g729a is loaded.
Sorry, wrong output for that.

Ah, g729 is indeed there for transcoding so it IS working. The codec_g729a module if installed will automatically give you channels on an activated FreePBX system. It must have a deployment id.

There’s a distro bash script that will install the free version

Open Source G729 codec is installed.
