Placing Multi-point Calls
When there are more than two parties participating in a video call it
is called a multi-point call. You can have up to four parties
participating in a call with the ViewStation FX or the VS4000. If you
have a PRI network interface, you can place multi-point calls over a
PRI line or over H.323 on the LAN. If you have a V.35 network
interface, you can place multi-point calls only over H.323 on the
LAN.
The following chart shows the maximum allowable dialing speeds
according to the number of sites in a call.
All parties in a multi-point call must be connected at the same speed.
You can place multi-point calls manually by adding sites to your
video calls, or you can create multi-point address book entries. For
information on creating multi-point address book entries, refer to the
