How to Test the Performance of a VoIP
Voice over Internet Protocol (VoIP) is a modern telephony system that uses the Internet to transport phone calls. The signals that VoIP transports are digital, and they are converted to and from analog before reaching older touch-tone telephones. A digital VoIP signal is compressed for faster transport, and this compression and digital to analog conversion can lead to unsatisfactory VoIP call performance. There are some standard methods to test the performance of VoIP calls to ensure you have the best performance possible.

Test Outbound VoIP Performance
-
1
Place a telephone call to an assistant and ask him or her about the call quality.
-
2
Place a VoIP call to an Interactive Voice Response (IVR) system. If the IVR does not respond when you speak clearly, it may signify quality issues. Any IVR using voice recognition can be used, but Google's search number, 1-800-GOOG-411, is one excellent option.

Call your own voice mail from the VoIP phone. Leave a message and call your voice mail from a second line to check the VoIP performance.
Test Inbound VoIP Performance
-
4
Ask an assistant to call you. Your assistant can tell you if he or she can reach your VoIP number and also about the connection quality.
-
5
Test your VoIP performance with an echo number, which allows you to talk and listen to an echo of yourself. The phone number 909-390-0003 can be used for an echo test. Nobody answers, but wait a few seconds then talk and listen to your echo.
-
6
Call your VoIP number from a second phone. If you are unable to enlist an assistant, this test will at least reveal if your VoIP phone takes incoming calls. Audio performance is more difficult to test alone, due to potential feedback between both lines.
