A conference can consist of any combination of ISDN/IP
sites.
It is possible to have telephone meetings with up to 5
participants.
The MultiSite supports both Voice Switched and
Continuous Presence mode (see 'MCU Services' in
'Advanced use' for description of these modes).
Establishing a conference is done by first making a call
to one site. When a call is established with the first site,
the other sites are connected one by one.
It is possible to either dial out to the sites or the sites
can dial in to the MultiSite.
Both ISDN, IP and mixed ISDN/IP conferences can be
encrypted if all systems supports encryption.
