To Reselect an Incoming or Outgoing Call
Incoming calls are indicated with a red arrow while outgoing ones are indicated with a green arrow;
a cyclic buffer of 60 numbers is available to store calls.
To reselect a called number press the CALL remote control key twice. A list will appear, and
numbers can be selected and modified.
TCS-4 Mode Video Call
The TCS-4 mode is an H.320 call (ISDN) to a gateway which is able to transcode H.320
(ISDN)/H.323 (IP).
The format for number entry is:
“ISDN number of gateway” followed by “#” followed by “H.323 number (E.164) of the terminal to
be called ”.
Audio call
If you would like to make an audio-only call (using the System like a normal telephone), select the
AUDIO icon from the Home Page.
To complete the audio call, follow these steps:
1. Select the type of call (ISDN, IP-H323, IP-SIP, NIC) from the drop-down menu.
2. Enter the number or the alias (IP) you want to call using the keys on the remote control or
the virtual keypad.
3. Move to the CALL icon and press OK to make the call, or press the CALL remote control
key.
To end communication, use the DISCONNECT remote control key: if enabled, the system will ask
you to confirm disconnection.
Secure Connections
The System can manage secure videoconference sessions via encrypted connections, in both point-
to-point and multipoint sessions. To do this, the encryption function must be enabled: for more
information, refer to the “Encryption” section of this manual.
Once encryption is properly configured, you can make a secure call by following the same
procedure described for a standard call.
Useful information:
The encryption status can be checked on the status bar. If the encryption is enabled and configured,
an icon showing a padlock is displayed on the status bar.
If the padlock is yellow and open (
), encryption has been enabled but the function is not active.
If the padlock is green and closed, encryption is active ( ).
If the padlock is red and closed, encryption is activated only in transmission ( )
