hi Emrah, there's a bunch of comments in FS-6947 which I guess you missed. As per standard, Opus codec always requires that RTP is encoded with 48000Hz stereo, and there's always up- and downsampling if you feed the codec with 8KHz sound.

Hi, 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. I see issue 6947 seems to be talking about the same thing and was wondering if something had been done about it. https://freeswitch.org/jira/browse/FS-6947
It shows it's been solved, but I cannot see any dialplan variables I could set to fine tune my Opus codec negotiation. _________________________________________________________________________ Professional FreeSWITCH Consulting Services: consulting@freeswitch.org http://www.freeswitchsolutions.com
