## About

VoIP Test measures the real conditions affecting voice calls on your network: latency, jitter, and packet loss. It uses synthetic media streams to simulate voice traffic without requiring microphone access or live calls. The goal is to end the blame game between ISPs and VoIP providers by showing exactly where in the path quality breaks down.
