Two tools that share one engine:

• ringo-phone — a terminal softphone: manage SIP accounts and place calls without leaving the keyboard.
• ringo-flow — a telephony scenario test runner: write call flows as Rhai scripts and run them headlessly in CI.

The source is on GitHub.

_{For tooling/agents: llms.txt indexes the docs, and the ringo-flow scenario API is available as Rhai type definitions (.d.rhai).}
