3cx phone Codecs

[Hitesh Patel]

Anyone know the best Audio Codec to use for Audio phone quality also is there a place in the Server manager to add different ones or remove ones not used

There have been some HD Codecs introduced recently and may be worth tying internally, but, they may not be available on all of your sets/devices, or over a VoIP trunk which would mean the call being transcoded through the PBX if you force the use, and one end cannot comply. The g711a / u (stick with the one your trunk provider uses), would be my first choice, unless there is a reason to save bandwidth.
