Media traffic volumes are generally not visible, because they're from endpoint to endpoint, so unless you've got really detailed monitoring (which the original poster said they didn't), you're not going to see traffic between two phones in the same building, or traffic between buildings that don't

Use about 100k per call for 711u and it will help make the numbers actually around 88.2k. I did say round you know! Lol... Things like VAD would drop the numbers even lower for G.711. nice and round. If you are trying to calculate busy hour search for Erlang on your neare

Hi, is there any statistics on aggregated VoIP signaling bandwidth and aggregated VoIP data bandwidth? eg. if we monitored there is 2Mbps(average) traffic on VoIP signaling protocol ports ( including SIP, H.323, MGCP), how could we estimate average VoIP data bandwidth? Joe As mentioned in pr

Your signaling traffic will be incredibly low compared to your RTP streams (especially for G.711u). For G.711u if 2Mbps is your peak think somewhere in the range of 10kbps or so (complete SWAG but I hope you get the picture). Use about 100k per call for 711u and it will help make the num
