# 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. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
