Use traffic shaping to offer voice traffic the necessary bandwidth
Due to potential contention of competing data on your network, it is important to ensure that your voice traffic has enough bandwidth to operate. As such, traffic shaping rules can be implemented to allow voice traffic to use additional bandwidth, or even limit other types of traffic to prioritize voice traffic.
QoS Settings
Protocol | Port Range | Priority |
|---|
UDP | 10000-20000 | DSCP 46 - EF
DSCP 56 - CS7 (for webRTC) |
UDP | 5060-5081 | DSCP 46 - EF |
Network Performance
Uninterrupted, consistent network performance is required for a good experience with the Sharpen platform. Due to the inherent nature of Voice interactions to be real-time, we need consistency in the underlying network. Otherwise, users may experience dropped calls, choppy call quality, latency, or an overall slow experience.
