4.3.1 Placing Multi-site Calls from the FX Hubs in Charlottesville and Socorro

To place calls to multiple sites from CV-aud, CV-ER311 or SO-conf, simply place the first call, then press MENU to get back to the Polycom Top Menu, place the second call, then (if neeeded) press MENU again and place the third call.

The FX hubs support 3-way meetings at 512 kbps using the regular point-to-point Address Book entries. Unless you are showing movies or other views with much movement, you can save video bandwidth with little loss in video quality (and none in audio quality) by dialing three-way connections at the NRAO default bandwidth of 384 kbps. To make connections at 512 kbps, use the Address Book entries that end in 512 if these are present on your system, or use the Video Phone (see below) to dial the IP address while setting the bandwidth to the higher value.

The FX hubs support 4-way meetings only at 384 kbps, so these must be dialed using the Address Book entries that end in 384.
