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.
Voice servervoice.pinecall.io
Audio transport
WebRTC, SIP, Twilio, WhatsApp — every channel, one event stream.
Speech-to-text
Deepgram, Gladia, AWS — streamed and transcribed in real time.
Text-to-speech
ElevenLabs, Cartesia — low latency, spoken sentence by sentence.
Turn detection & VAD
Knows when the caller is done. Handles barge-in and silence.
Every channel and every agent, multiplexed over a single connection.
