High-quality voice calls with RingCentral
Read about best practices and tools that will help you get the most from your service, and how your routers and your Internet connection contribute to overall call quality.
RingCentral provides you with reliable, high-quality voice service. Your local network, your Internet connection, and your router devices all contribute to overall call quality. To help you manage your call quality, RingCentral offers tools to check your Internet connection speed, and instructions to configure the Quality of Service (QoS) settings of your routers.
Factors that affect call quality
When making a Voice over IP (VoIP) phone call, the sound of your voice is broken into thousands of packets. These packets travel various paths on the Internet to RingCentral, and on to their final destination, where they are reassembled. Many factors can affect packets on this journey, and thus impact the quality of the call. The three most common: Latency, Jitter, and Packet Loss.
Improving your QoS
Design your network for voice, and use QoS-enabled network equipment.
There are special considerations when designing your network to support voice traffic. QoS-enabled routers prioritise voice traffic over lower-priority data traffic, such as large downloads.
Test your bandwidth
A solid Internet connection means solid voice quality.
For voice quality, we recommend that you use a high-speed DSL, cable, or fibre-optic connection with dedicated upload and download bandwidth for voice of 90Kbps or higher for each voice line you plan to run. Please use these Internet connection tests to verify your connection.
