User Guide for the VC400 Video Conferencing System
- If the 8 way MCU displays X~Y Available, it means you have imported a trail version
of 8-way conference license. So the system supports up to 8-way video calls and an
additional voice call (an original caller and eight other sites) in X~Y period. When the
trial license expires, your system supports 4-way video calls and an additional voice
call (an original caller and three other sites).
- If the 8 way MCU displays Eternal, it means you have imported a permanent version
of the 8-way conference license. So the system supports up to 8-way video calls and
an additional voice call (an original caller and eight other sites) permanently.
