Can someone please give me a quick lesson on this? I get that if I check it, then the PBX is processing the audio. Is this a good thing or a bad thing? I want to use G.722. My phones support it. I have v10 sp1 on a beast of a machine. I have a Gigabit network. I'm just not sure what is the best way to implement. My VOIP provider (callcentric) does not support G.722, but that doesn't stop me from using it internally and I may be switching. PLease help a newbie out. Thanks.
