Terminating a video conference
Calling participants one by one
Setting up a list of whom to call before calling them
Calling more than one (optional)
Provided that your video endpoint is equipped with the optional built-in Multisite 
feature, any point-to-point video call (a call involving two parties only) may be 
expanded to include additional participants. The call will then become a video 
conference. 
Any ongoing video call can then be expanded to a video conference by adding more 
participants at all times (see the right example).
Alternatively, you may set up a list of whom to call before you actually call them and 
then call them all in one go (see the below example).
Note that your video network may have an infrastructure permitting video conferencing—
even if your video system itself does not. This will require the presence of an external 
Multipoint Control Unit (MCU).
The most advanced video systems (those using Codec C60 or C90) can—when 
equipped with Multisite—set up video meetings with four participants (yourself 
included). External MCUs may let you set up conferences with many more 
participants. 
Systems equipped with Codec C20 have no Multisite feature (see  
 page 30 to 
nd out which type of codec your system has). However, all products described in this 
user guide come with Multiway
™
 installed (see the next page for more on this).
Contact your system administrator for details on how to use external MCUs.
This example shows two entries made before any 
calls are placed. 
To do this start by entering the rst person to call 
(directly, via the recent calls list or from the phone 
book), then select Add another participant and add 
a second person. When all have been entered, 
press Call on the remote control or select the Call 
icon in the menu.
For units equipped with MultiSite capabilities, up to 
three participants can be called simultaneously, if 
no external MCUs are used.
After you have entered the participants, press 
the
   key to place the calls. Any of these may, 
of course, be fetched from the phone book in the 
usual manner. 
During a call, open the Call menu again…
Then call someone in the usual manner—
by keying in the name, number or address 
(in this case “542”) or by means of the 
phone book. Invoke the virtual keyboard 
(see
   “Entering text in text elds” on 
page 7), if convenient.
Finally, navigate down to
   Call and 
place the call… 
If you want to add another participant, 
repeat the process. The maximum 
number of participants possible 
depends on your system’s conguration. 
This is the 
participant 
you already 
are in a call 
with.
The next 
participant 
you are 
going to 
call.
Use this 
to place 
the call.
The host of a video conference is the 
one who initiated the conference. This 
is the endpoint to which all the others 
are connected.
The host has the right to terminate the 
connection to any of the participants. 
The participants cannot control any 
of the others, but may disconnect 
themselves from the meeting at all 
times.
