Codec opus not working under IAX


I’m using FreePBX 14 with Asterisk 13 and installed the opus Codec and it works fine when using SIP but I just can’t get IAX to use opus.

I have noticed there is no opus in “host prefs” when I call in using IAX client and opus Codec

– > requested format = opus,
– > requested prefs = (),
– > actual format = g729,
– > host prefs = (ulaw|alaw|siren14|siren7|g722|slin16|slin|g726|g726aal2|adpcm|gsm|ilbc|speex|lpc10|g729|g723),

That’s correct. IAX doesn’t know how to negotiate Opus.
