Better Call Claude
This lets Claude make and receive phone calls, send SMS messages, and communicate via WhatsApp without you being at your keyboard. You can call Claude to kick off a refactor, then get a callback 20 minutes later when it hits a decision point. It supports Twilio and Telnyx for voice and SMS, plus a free Baileys integration that uses your personal WhatsApp account with no API costs. Context persists across channels, so you can start a conversation on a call and continue it via text. Setup involves either a phone provider account plus Tailscale Funnel for webhooks, or just the Baileys pairing flow if you only want WhatsApp. Best for long-running tasks where you want async updates on your phone instead of polling a terminal.
