[Freeswitch-users] OPUS and bitrate

Hi Michael,
Try a lower maxaveragebitrate together with :
<param name="maxplaybackrate" value="8000"/>
This will put Opus in Narrowband on Freeswitch side  (FS encoder). 
If Bria is respecting the FMTP params that FS sends , it should send Narrowband voice too .
I am not familiar with Bria , but if it shows 30-60 kb/s , perhaps it shows the "network bitrate" ( together with packet headers ).Note that maxaveragebitrate is the codec bitrate and actually Opus can go higher than that at times during the call but certainly not as high as 60 kb/s.

Regards,Dragos
