Quality of Service
RingCentral provides reliable, high-quality voice service. Your local
network, internet connection, and your router all contribute to overall call
quality, with sufficient dedicated bandwidth to voice calls being the biggest
factor. 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.
The QoS settings on your router enable it to give priority to real-time voice
traffic over lower-priority data traffic, such as large downloads. This
document provides recommended configuration settings to ensure the
highest-possible QoS experience on the Meraki MX64 Firewall/Router.
Please reference the relevant TCP/UDP settings on the
Ports and Firewalls
table to complete the recommended setup.

Note:
The routers recommended here are quality hardware that we
have tested internally and work reliably with our services.
However, given the constantly updated firmware and physical
changes made by manufacturers and the nature of cloud-based
services, RingCentral cannot control the final configuration of
the hardware or your computer systems/networks, or promise
that any given router will work with your system, or guarantee
that our information is 100% up to date.
Test Your Connection Capacity
The RingCentral
Connection Capacity test
will help determine the maximum
number of simultaneous RingCentral calls that can be supported on your
broadband connection. Run this test during normal business hours when the
connection is in use by other applications, including large file downloads.
The capacity test should be run using the maximum number of simultaneous
call connections needed, and should use the G.711 codec selection.
Specific requirements for QoS:
Bandwidth—100 Kbps up and down per call
Latency (one-way)—less than 150 ms
Jitter—not to exceed 100 ms
Packet loss—less than 3%
These requirements are the foundation for ensuring your local network can
support satisfactory VoIP. Failure to meet these requirements will result in
poor voice quality.
When the test completes, you will see the recommended number of
simultaneous calls your connection can support while maintaining good quality
voice calls.
