z『Main Menu』=>『8.Advanced』/『1.CODEC』/『1.Preferences』

zReorder the CODEC precedence：

i.0: Disable the selected CODEC

ii.1: Highest priority

iii.8: Lowest priority

Besides, you should just lower the priorities of G.711 in most circumstances rather than overly disabling them such that the phone could gracefully fall back to G.711A or G.711µ when the peer does not support those low bit-rate CODECs for voice compression.
