For VoIP, enough bandwidth must be supplied to allow for the transmission of voice data in real time. Measured in bits transferred per second, bandwidth is the maximum throughput of a network.

Internet connection capacity for voice calls - To maintain quality VoIP service, you must have enough bandwidth on your network to support VoIP call traffic. However, when latency is high enough, callers will start to notice the delay. Unlike jitter, latency doesn't usually degrade the sound quality. Expressed in milliseconds, latency specifically measures the time it takes to move a VoIP packet from one point to another. LatencyĪ delay in sound transmission - Latency is the amount of time it takes for sound to travel from one call participant to another. Simply put, callers will notice jitter as poor audio quality. Jitter is significant to real-time applications because the receiver must dimension its jitter buffer based on maximum jitter, which adds delays for all packets and causes eventual loss when jitter values exceed buffer capacity. JitterĪ potential sound quality issue (choppy sound) - Measured in milliseconds, jitter is the variation in packet transit delays (from serialization, propagation, and buffering effects on the stream). Here are some basic terms the VoIP Test uses. Here's a quick guide to understanding what your VoIP test results mean. If your connection does not meet the test's standards, your calls could suffer from subpar quality. A VoIP test tells you if your Internet connection is equipped for a cloud phone system.
