In an effort to reduce bandwidth usage, I've set all of my extensions to use G.729. My VOIP provider supports it, phones all support it - but for some reason, when I restrict G.711u, I can't connect to voicemail, ivr or anything that the pbx does itself. Is there a way to get the IVR/VM/etc to use G.729? All of my extensions are remote. Running 3cx V9 Beta 2 Thanks guys!
