The video calls in a conference must be connected using the same bandwidth.
TIP
| A conference can consist of any combination of ISDN/IP |

| 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. |

For encrypted calls, there is a maximum bandwidth of 768 Kbps for the whole conference. This means that a 3 site conference will have a maximum bandwidth of 384Kbps per connection, while a 4 site conference will have a maximum bandwidth of 256 Kbps per connection.
NOTE
THE SYSTEM SUPPORTS MIXED MULTISITE WITH V.35 AND IP, BUT THE IP SITE MUST BE ADDED AFTER THE V.35 IS UP AND RUNNING.
