Recommended QoS Configuration | TP-LINK Archer C3200 | Introduction
Introduction
RingCentral has taken the guesswork out of router selection. Because 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 VoIP conversations.
This document provides recommended configuration settings to ensure
the highest possible QoS for voice calls on the TP-LINK® Archer C3200
wireless router.
Additional routers that have been tested and recommended are shown on
the Recommended Routers page of the RingCentral Customer Care
website.
Supported Browsers for Test

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 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 TP-LINK Archer C3200 router. Please reference the
relevant TCP/UDP settings on the Ports and Firewalls table to complete the
recommended setup.
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.

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). A MOS score of 4 is good.

3. Click the Bandwidth Control tab; then enable the Bandwidth Control option. Set the Total Upstream Bandwidth and Total Downstream
Bandwidth in kbps based on your measured internet speeds. This can be accomplished using your ISP’s speed-test feature, via their
website. Example: Search for (via Google) "Comcast speed test", or "AT&T speed test"; then click on the link to your ISP’s website.

4. Under the same Bandwidth Control tab, you will need to prioritize your phones. To do this, click the Add button under Controlling Rules.
a. Under IP Range, enter the IP address range of the phones you wish to prioritize.
You can set DHCP reservations to allocate a block of IP address specifically for the RingCentral phones for a specific range. This can
be set up under Advanced > DHCP Server > Address Reservations.
b. Under Port Range, enter all ports used by RingCentral services. Default would be to cover them all using, 1000-65535.
c. Set Protocol to All.
d. Set Priority to 1.
e. Set Upstream & Downstream values based on your networks usage of phones. Keep in mind an active phone call takes 100 kbps in
both directions. Note: When you configure the IP address range, all phones in the range will share the allocated bandwidth.
f. Click OK to save the rule.
