Welcome to XCast Labs!

Use Our Tools

XCast Labs now provides several tools that can help you determine how Video and Voice over the Internet (VVoIP) services are likely to work in your environment. Our support team is available to help you if you have difficulty in conducting these preliminary tests which are described below.

In order to get yourself “VoIP Ready” you will want to evaluate the ease of implementing VoIP services at your residence or business. Most of today’s broadband services provide universal access except in isolated areas or unique situations. We can help you troubleshoot any issue you may have by helping you perform some preliminary tests.

These tests will help you measure your Internet connection for VoIP quality and report the level of VoIP sound quality you can expect. Running a VoIP speed test is an effective way to gauge whether your Internet connection is suitable for VoIP technology. A number of factors must be considered--including how many users you will have on a single internet connection and how many of those users will be on the phone at once.

For single user you will need to select the 1 line test described below. For multiple users you should select the 5 line test. You can easily perform these tests yourself once you have installed Java.

Conducting the tests: After you have downloaded Java you will need to determine whether you wish to conduct a test for capacity, for a single user (single line) or a test for multiple users (5 lines.) Here are the test sites:

Our sales or support can help you if you face difficulties. But, first here are a few definitions of terms you will need to know if you need to talk to one of our service representatives:

Fraud Detection & Management

Our XCast Labs' engineering team has been working hard for over a decade to develop and deliver the highest quality Voice and Video over the Internet (VVoIP) services to its customers. As part of that process we have developed many tools that are part of our platform and suite of products and services. We believe these tools can also help our customers evaluate, monitor and optimize their own networks. To express our appreciation to our customers and the VoIP community, that has helped us grow our business, we will begin providing free tools and solutions that we hope will help you grow your business.

Fraud Detection and Risk Management are growing problems in our industry. XCast Labs has successfully protected its network by developing software that ensures continuous and comprehensive monitoring. This tool can reduce the likelihood that fraud can go undetected. Therefore, our first release is a Fraud Detection and Reporting System (FD&RS). We encourage you to join our effort in utilizing and improving FD&RS. The current release is available under GNU GPLv3 license from HERE.

Definitions of Terms

Jitter is a measure for the difference in time that each packet takes to reach the destination.
Packet Loss is a measure of how many packets did not reach the destination for one reason or another, expressed as a percentage of the total number of packets. Any packet loss can affect the quality of applications.
Packet Order is a measure in percentage of how many packets arrived in order. This results in packets arriving out of order which causes other packets to be delayed or even in very bad cases discarded. Delayed or discarded packets sometimes cause a quality problem for the application.
Packet Discards is a measure of packets that arrive too late to be used by the application. Packets are very time dependent when it comes to media based applications. There is a time window when packets can be used after which it is too late and the packet has to be intentionally discarded when it arrives.

MOS Score

You can also perform a subjective test that will allow you to get an MOS score based on this five point scale (with “5” as the best and “1” as the worst). Here are the subjective measurements:

5 – Clear as if in a real face to face conversation.
4 – Fair, small interference but sound still clear. Cell phones are a good example of an everyday experience.
3 – Less than fair, enough interference to start to annoy.
2 – Poor, very annoying.

1 – Inadequate for your purposes.
