VoIP Signal Testing

Test your VoIP signals to ensure the best calls possible.

At first thought, you might think that the VoIP, or Voice over Internet Protocol, signal refers only to the wireless connection between your VoIP device and the Internet. In addition to these wireless signals, however, VoIP must also use voice and receiver signals. Testing that these signals work correctly will ensure that your VoIP device performs to the best of its ability.

Signal Basics

When you speak into your VoIP handset or headset, the device converts your voice into a digital signal. This signal is then sent over the Internet using an Internet protocol. If you're speaking to a landline phone, the signal is then converted back to signals the analog phone can interpret. When the other person speaks to you the signal is sent to your phone and received in reverse.

Testing

When you test a signal, you don't just look for the signal or signal strength. Testing also analyzes that the signals are being sent in relation to which are being received. For example, one aspect that these signals, sent in a number of different wave types depending upon the type of VoIP system you own, test is the amount of voice distortion caused by the system. If you can detect and remove the distortion, the quality of your call will improve.

Testing Software

VoIP services do not come with built-in testing software, although the provider may sell it to you separately. In order to find signal testing software, begin by checking your provider's website. If you see nothing there, call customer service or browse other VoIP provider websites. Good software should specifically list that it tests VoIP signals and be compatible with your computer operating system.
