AVC Conferencing - Video Switching
During a Video Switching conference, each endpoint uses one video (CIF) port.
AVC Conferencing - Voice
One Audio Only resource is used to connect a single voice participant when CIF resources
have been converted to Audio Only. However, if no CIF resources were converted, Audio
Only endpoints use one CIF video resource per connection.
When video ports are fully used, the system cannot use free audio ports for video. When
audio port resources are fully used, video ports can be used, using one video port to connect
one voice participant.
