VoIP Test - VoIP Quality Test Tool

VoIP Quality & Bandwidth

Think of your VoIP service like any other application that uses the internet. Bandwidth determines the volume of information you can transfer at a time.

If your internet connection is slow or if bandwidth is being drained by multiple other applications, you would expect a streaming video to take longer to load or for quality to drop. The same is true of VoIP quality.

The more people you have using a VoIP phone service, the more bandwidth is demanded. Without enough bandwidth, you may not be able to support the VoIP system and users you need.

VoIP & Internet Quality

Having enough bandwidth isn’t the only thing to consider when using a VoIP quality test. The speed, accuracy and deliverability at which information can be exchanged is also critical since VoIP information needs to be sent in real-time for a good call experience.

Poor speed, packet loss, latency or jitter will result in poor call quality, lag, and choppiness. Latency, jitter, and packet loss all have to do with the speed and success of information being sent and received.

Packet Loss

Packet loss occurs when packets of data do not reach their intended destination - usually because of network congestion. A high packet loss percentage will indicate that you are trying to move more information than your present network can support, resulting in packets being dropped. you've experienced packet loss during a VoIP call when someone cuts in and out, or when a video becomes choppy or glitchy since the information isn't reaching its intended destination. For the purposes of our test, we assume no packet loss.

Latency

Latency is the measure of time it takes for information to be encoded and delivered to the intended destination.

When latency is high, the timing of the conversation is off, words and phrases may overlap causing users start talking over one another unintentionally.

Jitter

Jitter is the variation in packet / information arrival time. High jitter, or high variation in delivery time, results in choppy voice calls or glitchy-sounding phone calls.
