Voice & messaging (WhatsApp, SMS, receptionist)
Talk to Otter, text it, or let it answer the phone and book for you.
Otter isn't only in the app. It reaches you (and your callers) over voice, WhatsApp, and SMS - all confirm-first, all optional, all off until you configure the channel.
Talk to Otter over WhatsApp / SMS
With Twilio connected, text the number in your settings to ask Otter to book, move, or check meetings from your phone's messaging app. It replies with a draft; reply YES to confirm. Great for capturing a scheduling thought the moment you have it.
The AI voice receptionist
Point a Twilio phone number's voice webhook at DayOtter and Otter can answer calls for one host - understand what the caller needs, answer from a knowledge source you provide, and hand them a booking link (or text it) to lock in a time. Set VOICE_RECEPTIONIST_HANDLE to the host it answers for.
Heads up
Inbound webhooks are verified with Twilio's signature and fail closed, so only genuine Twilio requests are processed. Register your webhooks at ${APP_URL}/api/webhooks/twilio (messaging) and .../voice (voice).
