But what if you want to find out something more specific, such as whether your connection has the consistency of bidirectional throughput required to support Voice over IP? The answer: take the VoIP Test.
The site will tell you if you have a latency problem that could impact on VoIP, how many concurrent calls your bandwidth will support, or if the necessary protocols can traverse unimpeded to and from your network.
By simulating a number of two-way VoIP calls at the same time, the test determines your real-world simultaneous internet voice-call capability. But make sure you enter the site via dslreports.com reports because the bandwidth.com homepage requires a valid US zip code.
