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

No, that isn't loaded. It wasn't being built.  I think thatt my third party codec doesn't support annexb either.


These were the options used to build:

> I noticed this issue when attempting to pass through G729 from a yealink to an upstream trunk using Cisco ENSR.
> Asterisk was sometimes allowing VAD to be enabled, which is not supported as this is part of G729 ANNEX B. Call was made from yealink to cisco via asterisk. There was no annexb=no being sent. I tried this patch and the problem went away.
> <removed inline patch>
