“Resume Call” is not available when the remote party has operated the system to enter
the hold mode during a point-to-point videoconference. Only “Disconnect” is available.
To put a call on hold during a multipoint videoconference
The operations to enter/cancel the hold mode are the same as those for a point-
to-point videoconference.
See “To put a call on hold during a point-to-point videoconference” and “To
cancel the hold mode of a point-to-point videoconference” above.
The following differences regarding the operation and display are observed
during a multipoint videoconference:
• When a multipoint videoconference is conducted with the MCU software
installed in the local system, and the local system puts a call on hold, all the
connected terminals enter the hold mode simultaneously and the “On Hold
(SIP)” display appears on the display of each site.
However, if a multipoint videoconference is conducted with the terminals
connected by SIP and other line interfaces mixed, the local system cannot put
a call on hold.
• When a multipoint videoconference is conducted in the Split mode with the
MCU software installed in the local system, and any of the connected
terminals puts a call on hold, the picture of that site changes to the “On Hold
(SIP)” display. In this case, you cannot put a call on hold from the local
system. If all the connected terminals put a call on hold, only the picture of
the local site is displayed.
• When a multipoint videoconference is conducted in the Voice Activate mode
with the MCU software installed in the local system, and if a connected
terminal being broadcast puts a call on hold, only that terminal enters the
hold mode and the local picture is shown on the other terminals. If a
connected terminal that is not being broadcast puts a call on hold, the
broadcasting continues.
