Specifying Quality of Service

Points to note about SIP:
The SIP protocol has been widely adapted for voice over IP communications and
basic video conferencing; however, many of the advanced video conferencing
capabilities are not yet standardized. Many capabilities also depend on the SIP
server.
Set the Quality of Service options for the way your network handles IP packets
during video calls.
To specify Quality of Service:
1. Go to System > Admin Settings > Network > IP > Quality of Service.
2. Configure these settings on the Quality of Service screen:
