No paid telephony. No extra API key for the conversation: the model already driving the MCP is the voice on the line. Highlights - 📞 Two-way voice calls — the agent rings your phone, you talk, it transcribes you and replies in speech. Barge-in : talk over it and it stops. - 🔔 Tiered alerts — a loud push (ntfy / Pushover) or a real SIP ring + chat message, fired only when the LLM judges it urgent. - 🆓 Free & self-hosted — pjsua2 + whisper.cpp + Piper neural TTS + a free Linphone SIP account. No Twilio, no per-minute fees. - 🧠 No conversation API key — the calling model is the brain; these tools are just its ears and mouth. It ships two MCP servers, ringback-alert and ringback-voice : Platform: macOS, Linux , and Windows (via WSL2 or Docker). TTS is Piper by default (same voice everywhere), falling back to the OS-native voice ( say on macOS). The engine is headless — it never opens a local mic/speaker (all audio is WAV ↔ SIP/RTP), so no sound card is required. Setup guides: macOS · Linux · Windows · Docker. Server Tools What it does --- --- --- ringback-alert alert me , alert test , alert status Fire-and-forget notification: a loud push (ntfy / Pushover) and/or a SIP ring + chat message. ringback-v","default_branch":null,"files":null,"tree":[],"storefront":"/r/mohitbadwal","claimed":false,"request_supported":{"post":"https://gitbuyer.com/r/mohitbadwal/ringback/request-supported","requests":0},"note":"indexed from public GitHub; nothing is for sale on this page.
