By default, the system automatically detects the available bandwidth and uses this connection
speed. 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.
The uplink bandwidth refers to the max bandwidth of outgoing calls. The downlink bandwidth
refers to the max bandwidth of incoming calls.
Available bandwidths for the system are: Auto, 256kb/s, 384kb/s, 512 kb/s, 640 kb/s, 768 kb/s,
