VoIP Webmaster Calculator

Well, I’m not saying my idea is the best, but it’s the way some vendors are suggesting networks are planned.

Yes, we’ll be taking voice compression into account. G.729 seems to be standard(ish) across the wide area network at least. It’s an 8kbps algorithm, but there is a large overhead in wrapping the payload in IP, UDP and RTP.

I’m interested in what effect Silence Suppression has on quality and bandwidth, but I think I’ll start another thread about that.

I’m not sure what coding scheme LAN PBXs use. Without the constraints on bandwidth which exist on the WAN, I guess full 64kbps would be reasonable. Anyone know what happens in practice?
