MCU Connection
By connecting to an MCU (multipoint control unit), you can make multiple-party video conference calls with 5
or more parties, rather than the normal maximum of 4 parties (Page 49).

For details about the types of MCUs you can connect to, contact your dealer. Communication cannot be encrypted when you connect
to an MCU. Instead, connect over an intranet or via a VPN (Virtual Private Network).
