Transcoding Only when there is No Common Codec

Hi Everyone
Please is it possible to Disable Transcoding on Yeti Switch?

Or better still use a Common Codec when possible? Example
Offer == (PCMA, PCMU,G729)
Answer == (PCMU)

Yeti-Switch will transcode from PCMA to PCMU because PCMA had higher priority at the Offer…

But since PCMU is Common, is it possible to tell Yeti to use the Common Codec?

It will depends what codec negotiated on other leg - you can affect it by configuring codec groups
