MCS MyVoIP very accurately measures the quality and performance of Internet connections for Voice over IP (VoIP) usage by simulating UDP voice data traffic between a server and browser clients. Connections are tested for jitter and packet loss and rated for the supported level of sound quality.

The test can further be combined with a bandwidth speed test or network route diagnostics for more in-depth connection analysis.
