Division of labor
You own the what.
Pinecall runs the how.
The voice server handles the hard real-time parts — audio, transcription, speech, turn-taking. Your code handles everything that makes the agent yours.
Your codein your process
Prompts & personality
Who the agent is and how it speaks — versioned in your repo.
Tools as local functions
Plain functions with Zod schemas, auto-run inside your process.
Business logic & your data
Your database, your APIs, your auth. Nothing leaves the process.
When calls start & stop
React to events: greet, look up the caller, transfer, persist.

Audio transport
WebRTC, SIP, Twilio, WhatsApp — every channel, one event stream.
Speech-to-text

Turn detection & VAD
Knows when the caller is done. Handles barge-in and silence.
