Recommended QoS Configuration
Settings for
SONICWALL SOHO Router
Introduction
RingCentral® has taken the “guesswork” out of router selection. Since we know
that Quality of Service (QoS) is paramount to your business, we have carefully
selected and tested a set of dependable routers suitable for supporting high
quality Voice-over-IP conversations.
This document provides recommended configuration settings to ensure the
highest possible QoS for voice calls on the SONICWALL® SOHO wireless router.
Additional routers that have been tested and recommended are shown on the
Recommended Routers
page of the RingCentral website.
Supported browsers for test
- Internet Explorer 11 or higher (Windows XP, 7, 8 or higher)
- Firefox version 36 or higher (Windows and Mac)
- Safari version 6.2 or higher (Mac)
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.
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 Quality of Service (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 on the SONICWALL SOHO router. After configuring your router for optimum QoS, select port and firewall settings for mobile and softphone apps from the table here.
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 100Kbps up and down per call;
Latency (one-way) less than 150ms; Jitter not to exceed 100ms; 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.
Test your connection quality
RingCentral provides a VoIP Quality
test that will simulate VoIP
calls between your computer and RingCentral, and provide an estimate of the
voice quality you should expect when using our service. For the most accurate
results, run this test at least three different times throughout a business
day, and during peak usage times, while connected to the network that you plan
to use for RingCentral.
A two-minute test is typically sufficient, while longer tests are useful to
find intermittent problems or to simultaneously test VoIP performance along
with other traffic such as file transfers or remote access. Select the maximum
number of simultaneous users you expect to support, and set the test duration
between 1 and 5 minutes; 2 minutes is considered sufficient in most instances.
Click jitter and packet loss on the RESULTS SUMMARY panel to view the overall
quality of your expected VoIP connection.
MOS score (Mean Opinion Score) refers to a test that has been used for decades
in telephony networks to obtain the human user’s view of the quality of the
network. The MOS is the arithmetic mean of all the individual scores, and can
range from 1 (worst) to 5 (best). An MOS score of 4 is good.

- Log into the SONICWALL router with administrative permissions. The default username is admin and the default password is admin. Click OK.
- the left side of the page, expand VoIP / Settings.
Check the Enable consistent NAT box and uncheck all other settings. Select Accept to save the changes. (See the graphic on the next page.) On the left side of the page, expand VoIP / Settings – illustrated; see instructions above.
- Go to Firewall Settings / BWM.
3A. Under Bandwidth Management Type, select Global.
3B. Under Priority, disable EVERY category, except for Medium, which is enabled by default; set Guaranteed to 50%; Maximum\Burst to 100%.
3C. Enable Realtime; set Guaranteed to 50%; Maximum\Burst to 100%.
3D. Click Accept to save changes/settings.
- Go to Network / Interfaces / X1 (WAN).
4A. Under the General tab, click the Configure icon (on far right).
4B. Go to Advanced tab > Link Speed: and set to Auto Negotiate (UNLESS there’s a need to set it to something specific)
4C. Under Bandwidth Management check Enable Egress; set Interface Egress Bandwidth to match the available bandwidth;
check Enable Ingress; set Interface Ingress Bandwidth to match the available bandwidth.
4D. Click OK to save changes/settings.
- On the left side of the page, Expand Network. Select Address Objects and create objects and subnet masks for 80.81.128.0/255.255.240.0; 103.44.68.0/255.255.255.0; 104.245.56.0/255.255.248.0; 185.23.248.0/255.255.252.0; 192.209.24.0/255.255.248; 199.68.212.0/255.255.252.0; 199.255.120.0/255.255.252.0; 208.87.40.0/255.255.252.0 as shown at bottom.
