What’s the capabilities of the Opus codec in Yealink devices?


Yealink Phone support VBR (Variable Bit Rate) and CBR (Constant Bit Rate) in Opus codec, but didn’t support FEC (Forward Error Correction).

For the Min and Max bitrates, each pattern has a bit rate range (Min and Max bitrates), and the VBR will jump in this range when coding.
