Conference type


You can choose between three different type of conferences:

Audio Conference


An Audio conference are used to simply join several phone devices into one voice based conference. To join such a conference, please follow these instructions: Note:
  1. When connecting to an audio conference using a H.323 compatible videoconference equipment, it is possible to communicate using audio only.
  2. Sending content in an audio conference is not enabled as phone devices are unable to receive such streams.
  3. Booking a video enabled conference (Voice Switched or Continuous Presence, see below) will enable participants connecting using ordinary telephone devices. However, phone devices will only be able to receive audio streams.

Voice Switched


In a Voice Switched videoconference only the speeking participant will be shown on the screen. If there are more speakers at a time the loudest speaking participant can be seen, the MCU will decide which participant will appear on your monitor according to the volume of the audio signal coming from each talking participant. A Voice Switched videoconference can be optimal for meetings, where each participant speaks for a long time (e.g. one of the participants has a presentation or is teaching students, etc.).

Continuous Presence

A Continuous Presence videoconference is capable of showing all of the participants or just some of them jointly on your screen. This is achieved by the MCU by showing more participants in different areas of the screen. A Continuous Presence videoconference can be optimal for meetings, that require intense interactivity (e.g. project meetings, discussions, etc.).
In order to create a Continuous Presence videoconference you need to chose an appropriate screen layout according to the estimated number of conference particpants. The below illustrations show the possible screen layouts:

When using a layout with one bigger participant parcel the MCU will show the loudest speaking participant in this large part of the screen. In case the numer of participants exceeds the number of parcels in a layout only the last speakers will be shown on your monitor.
