| Medium | Min | High Quality |
| Data | 56kbps | 56kbps |
| Voice | 50kbps | 80kbps |
| Video | 50kbps | 350kbps |
| RoundTable (Conference video phone) | 50kbps | 350kbps |
Note that the requirements are cumulative –
Data + Voice + Video =
56 + 50 + 50 = 156kbps (Minimum Quality)
or
56 + 80 + 250 = 386kbps (High Quality)”
Here are some calculations I have used. however the 300KBps is only video stream single direction. Bidirectional video consists of two streams..
The following formula can provide rough bandwidth consumption estimates for conferencing with Audio / Video.
Note: Calculation results will be displayed in Mbps
CC = Concurrent Conferences
PPC = Participants Per Conference
