Codec help on SIP and phone needed

Hello all. Have a hosted by 3cx instance, version 20, update 7 using a supported Flowroute SIP trunk and all Yealink T54w phones setup as router phones. The below screenshots list the codec defaults for the trunk and the phones. Please let me know if the order should be changed or rearranged for best/audio performance. Thank you.

Hello craigps,

The IP Phone, 3CX Server and SIP Trunk will accept the first 'match' of codec.
As they all have the 'PCMU' codec as first codec, it is obvious that this will be the codec taken... never anything else.
In short, this is fine, as pcmu is the general audio codec with IP calls.
