Cisco video systems capable of 
video conferencing offer three ways 
of implementing the ability to be in a 
call with more than one, viz by means 
of: 
• 
Multipoint Control Unit (MCU)
This is a bridge that interconnects 
calls from several sources. All 
parties call the MCU unit, or the 
MCU unit calls them. This means 
that all participants will be in a 
point-to-point call with the MCU. 
If an MCU is used in your office, 
consult your System Administrator 
for operating details.
• 
MultiSite, an optional built-in 
MCU in your video system that 
allows you to call more than 
one. The video systems that you 
call will need no conferencing 
capabilities. The maximum number 
of participants will be four (yourself 
included) plus one audio-only call.
• 
Multiway, an optional feature that 
transfers your call to an external 
MCU as soon as you start calling 
more than one. However, you do 
control it all directly from your 
system. You will not have to call an 
MCU and then do everything from 
there.
Creating a video conference
Video conferencing
This is an optional feature that may, or may not, be installed on your system.
Video conferencing using an external MCU (with or without Multiway)
Any limitations 
to the number 
of simultaneous 
participants will 
depend entirely on 
the configuration 
implemented. 
The maximum number 
of simultaneous 
participants is four 
(yourself included) 
plus one audio-only 
call. 
Video conferencing using MultiSite (an equivalent to an embedded MCU)
Participants 2 and 3 experience this call as 
a point-to-point call with an MCU. They will 
therefore not need to have any conferencing 
abilities built in.
