sipstress is a Python SIP call generator and diagnostic tool. It places real INVITE dialogs through a director (SBC / OpenSIPS / similar), keeps RTP open for a configurable time, then hangs up. It does not embed your whole IVR it drives the SIP/RTP leg and records what the network and platform did: response codes, timings, jitter, loss, per-call traces, optional WAV captures, and PASS/FAIL health checks.
