Phone calls, SMS, and email — so your agents can reach humans in the real world.
Spix gives AI agents real communication capabilities. Your agent gets a dedicated phone number and email address, then uses them to make calls, send texts, and send emails — just like a human would.
Phone Calls — Outbound voice calls with real-time speech, automatic transcription, answering machine detection, and sub-300ms latency.
SMS — Send and receive text messages from a dedicated number with compliance handling built in.
Email — Send and receive from a real address with thread history and attachment support.
