# Voice

Our UDP jitter test is designed to measure the suitability of a connection for voice over IP (VoIP) traffic. While it does not measure the performance of any specific VoIP service, it can help you understand the quality of any potential VoIP calls on your line. See [UDP Jitter Test](https://docs.thousandeyes.com/product-documentation/connected-devices/connected-devices-tests/network/latency-loss-disconnections-jitter-tests#udp-jitter-test) to learn more.
