Bandwidth
The system automatically detects the available bandwidth for call connection by default. The
VC800 supports connecting to other devices with different bandwidth. If a device with lower
bandwidth joins a call, the video quality will stay the same or will not reduce a lot. You can
specify the uplink and downlink bandwidths for the system to achieve the best result. Uplink
bandwidth is the max bandwidth of outgoing calls. And downlink bandwidth is the max
bandwidth of incoming calls.
The configurable bandwidths on the system are: 256 kb/s, 384 kb/s, 512 kb/s, 640 kb/s, 768 kb/s,
1024 kb/s, 1280 kb/s, 1500 kb/s, 2000 kb/s, 3000 kb/s, 4000 kb/s.

Bandwidth settings parameters on the system are described below:
