I use Opus even for narrowband calls because of all its bells and whistles that PCM doesn't have. The trouble is that I always end up negotiating a crazy sampling rate, more demanding in every way and not necessary for a basic narrowband call. I know this because if I record the call, one leg is recording a full 48kHz audio that is unbelievable and the other one is a regular 8kHz sad PSTN call. I have 40kHz going to waste here.<br class="">
I see issue 6947 seems to be talking about the same thing and was wondering if something had been done about it.<br class="">

<br class="">
It shows it's been solved, but I cannot see any dialplan variables I could set to fine tune my Opus codec negotiation.<br class="">
