Recommended QoS Configuration | AdTran NetVanta 3448 | Introduction

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 AdTran®NetVanta®3448

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

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 AdTran NetVanta 3448 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 page 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.
