Use Quality of Service to maintain prioritization
Configuring Quality of Service (QoS) can help to maintain traffic priority across the network. It is beneficial to tag your voice traffic with the appropriate tags, so it can be prioritized anywhere in the network in the event of saturation. This will help to prevent any audio issues caused by voice and data competing for the same bandwidth over your internet connection.
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.

WebRTC is an HTML5 specification which can be used to facilitate real-time media communications (video and audio) between browsers and other audio endpoints. The Sharpen Q phone built into the Sharpen Q application leverages WebRTC, allowing for seamless integration to the platform within the browser. *See “Ports and Protocols” above to make sure you have the proper ports open.

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.

Chrome by default blocks port 5060, which is what Sharpen’s speedtest uses. Flags need to be set when Chrome is launched. Instructions for Windows, Mac, and Linux can be found here. |
