Option	Description
Video Session	Select the appropriate Video Session:
	Video Switching - To set a conference in which all
	the participants use the same video and audio
	formats, by setting the communication parameters to
	the common capabilities. Whenever a participant
	starts to speak, he/she appears on all screens as the
	conference is a voice activated video switching
	conference. All participants view the participant who
	is the speaker. Up to 16 or 30 participants (if at least
	one Audio Bridge is set to 1/30) can take part in a
	Video Switching conference using the standard
	Audio card. Up to 100 participants at 128Kbps can
	take part in a conference running on the Audio+
	card.
	Transcoding - To set a conference in which
	participants use different video, audio and data
	formats, maintaining the highest video and audio
	capability each participant can achieve with his/her
	codec. Like Video Switching, the current speaker is
	displayed on all terminals.
	Transcoding is performed on the following:
	•	Line rate
	•	Audio algorithm
	•	Video format
	•	Frame rate
	•	Restricted/non-restricted
	•	Bonding/non-bonding
	•	Different data rates
	Continuous Presence (CP) - A Continuous
	Presence conference is a conference in which
	several participants can be viewed simultaneously.
	Each participant uses their own codec capabilities,
	thus maintaining the highest video, audio and data
	capability that can be achieved.
