Luke Escude commented on ASTERISK-26478:
----------------------------------------

Kevin - it seems as though we've resolved the one-way audio issues in general, using uLaw. The issues were with several new customers at the same time, and we hadn't worked with their firewalls.

However, we did move a beta customer to 13.12.1 and enabled opus, and he continued to have one-way audio with Opus. Unfortunately he declined further beta testing, so now it's up to me to try and recreate the issues. We don't have Pcaps from those calls.

So there are still issues with Opus transcoding.

> Are there any known issues with transcoding with the Opus codec from Digium?
> About 1 in every 4 handsets is having one-way audio problems on Opus, during outbound calls (handset -> opus -> Asterisk 14 -> uLaw -> Trunk)
> It could be the handsets themselves as well, since Grandstream only recently started supporting opus.
