----------------------------------------

Kevin,

So while we're able to reproduce this 100% on our testbed server, Opus is working perfectly on our production server. So this might be environment/compiling related.

HOWEVER, on production server (running 13.14 with NEW codec_opus released in Feb), running "pjsip show channelstats" still shows uLaw for an endpoint definitely running Opus. Not sure if that's just a text output bug or something significant.

> The following codecs are configured for an endpoint, in order of priority:
> Opus
> uLaw
> iLBC
> g729
> Asterisk and the handset settle on Opus being the codec for the call, but no audio can be heard from the echo test (or extension-to-extension, or anything).
> Running "pjsip show channelstats" shows uLaw as the codec, even though it should say Opus. opus-debug file shows a lot of the following error:
> Oooh, got a frame with format of opus on channel 'PJSIP/100-0000001d' when we're sending 'ulaw', switching to match
