How much bandwidth do you need for a Polycom videoconference call? It's roughly the same as for Skype. Here's information from the Polycom Network Planning Worksheet. "The bandwidth required at the bridge equals the aggregate bandwidth of all the endpoints served by the bridge at any given time. In other words, if a particular bridge serves five endpoints, you will need 5 x the bandwidth required by each endpoint at the bridge location. For example, if five endpoints called into the bridge at 1Mbps each, the total amount of bandwidth needed at the bridge location is 5Mbps. Remember that different types of calls require different amounts of bandwidth: "

Voice caller 64Kbps
CIF caller (non-HD endpoints) 128Kbps
4CIF caller, or SD caller (ex: QDX 6000) 256Kbps
HD caller at 720p, 30fps 1Mbps
HD caller at 720p, 60fps 2Mbps
HD caller at 1080p, 30fps 4Mbps
