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

Alright so now I'm reliably getting Opus to constantly have one-way audio - however only on outbound calls.

An outbound call, like Handset -> Opus-8000 -> Asterisk -> uLaw-8000 -> Flowroute. The cell phone (flowroute side) can hear the Opus phone, but the Opus phone hears nothing.

Inbound calls don't seem to have the issue.

Additionally, core show translation shows 2 Opus columns and 2 Opus rows.

> 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.
