sipx-cli

sipx — a command line SIP softphone.

What this is

A scriptable diagnostic phone for registering, placing, answering, and inspecting calls. It also provides a finite, machine-ready load-responder with explicit admission, dialog-lifetime and cleanup bounds for reproducible signalling measurements. Its JSON output, exit statuses, and separation of logs from stdout make the call outcome assertable from a shell.

WAV input is mono 16-bit PCM at the negotiated media clock: 8 kHz for G.711 or 48 kHz for Opus. The phone refuses a mismatched rate instead of silently changing playback speed, takes packet size from the running session in both call roles, and writes that same clock into recording headers.

Stability

The supported command-line contract is maintained in the binary documentation's Stability section. That is the contract; it is linked rather than copied here so the two cannot drift.

Deliberately absent

This package has no Rust library target. Applications embedding sipx should depend on the relevant library crates instead of treating command internals as an API.
