Receiving A Call From A Remote Party - Sony Ipela PCS-XG80S Operating Instructions Manual

Some positions were not connected.
Start Meeting
Disconnect All Redial
Start Meeting: Starts communication with remote parties connected.
Disconnect All: Cancels all the connections and restores the Home menu.
Redial: Redials the numbers of the points that you failed to connect.
Note on multipoint videoconferences using ISDN
If the number of remote points connected increases as a result of dialing from
the main terminal while making a multipoint connection using ISDN, some of
the channels that have been used for connection will be cut off and used for the
newly connected points instead. For example, if you use six ISDN lines (up to
12B channels available), 12B channels will be used for the first remote point
only when no other points are connected. When the system connects to a
second point, the number of channels for the first point decreases, and 6B
channels will be used for both the first and second points.
Even if one of the remote points in a multipoint connection is disconnected, the
number of channels used for the remaining points will not increase.
