Implementation has been done using CCM 4.2, gatekeeper, IPVC MCU, VT Advantage and Tandberg. I am trying to monitor the bandwidth consumption for video call/conference. For one video call session using VT Advantage, it needs 500-700kbps. For one video call session using Tandberg, it needs 300s kbps for quality better than VT Advantage.
1> Is there a way to keep the link more efficient when using VT Advantage ?
2> What makes Tandberg showing better video quality with lower bandwidht comsumption than VT Advantage ?
3> Is there a way to compress the video packet ?
4> what is the best network setup for video conferencing ?
