[Freeswitch-users] Fine tuning Opus in dialplan

[Stanislav Sinyagin]

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.

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.
