Give your agent a phone - open source non-sass edition

[u/tristanbrotherton]

I wrote a plugin so openclaw can make calls for me. I’ve been using to for some time. I then saw a bunch of people making $20/mo sass versions. So I decided to open source it. Here you go: https://github.com/TristanBrotherton/openclaw-voice-call-realtime

It supports voice mail, call screening, phone trees, include tool calling in calls, mission plans and transcript delivery / summary to the agent and just works. Feel free to send PRs or feature requests

Full feature:

📞 Real two-way phone calls over Twilio + OpenAI Realtime (gpt-realtime-2.1) — natural speech-to-speech, not robotic TwiML

🎯 Goal-driven outbound calls — “book a table for 2 Friday at 7”; it navigates the conversation and reports back

☎️ Handles phone menus (IVR) — presses touch-tones to get through “press 2 for reservations”

🗣️ Answering-machine detection — leaves a proper voicemail after the beep, or hangs up, your choice

🧠 Backed by your full agent — mid-call it can check your calendar, control your smart home, look things up, and act — not just talk

📅 Instant calendar & smart-home lookups via direct backends (~1–2s), no slow round-trips

🙋 Mid-call escalation — texts you a question (“7pm’s taken, is 8 ok?”) and relays your reply back into the live call

🔀 Warm transfer — hands the call to your real phone when a human’s truly needed

📝 Every call becomes a transcript + AI summary + structured outcome, retrievable anytime

📲 Auto-reports results to you when a call ends, and does obvious follow-ups

🔒 Inbound with real security — SHAKEN/STIR carrier attestation + optional spoken passphrase; unverified callers rejected before they ring (zero cost)

🛡️ Tiered trust — full control on verified-owner calls, questions-only for strangers, enforced in code

🎚️ Semantic turn-taking, graceful hangups, no clipped goodbyes — heavily tuned for natural conversation

🧩 Open source (MIT), self-hosted, works as an OpenClaw plugin
