The flow · end-to-end

Phone → Speech → your endpoint.

Unpod handles the phone and the speech. You receive text at your endpoint and reply with text - the prompt, tools and customer data stay on your side.

How it works

Build the flow, then plug in speech.

Author the conversation in the IDE with developer-grade control, attach speech and a real number, wire it into your workflows and legacy systems, then ship.

What you can build with it

Real things you ship with Unpod - from coding agents that take calls to on-call pagers and 2FA inboxes.

Phone-call your codebase

Call a number, speak a command, and your coding agent runs it over MCP.

Native MCP

Autonomous AI workers

Give a long-running agent a real number to dial vendors and follow up, hands-free.

< 10 lines

AI receptionist

Answer inbound 24/7, qualify intent, book meetings, and warm-transfer with context.

1 webhook

On-call & incidents

Pager-style escalation — dial the on-call engineer, read the incident, escalate on no answer.

WSS streamed

Outbound follow-up

Trigger an outbound dial with one API call; the transcript streams back in real time.

1 API call

2FA & verification

A dedicated number for codes from Stripe, GitHub, or banks — SMS lands in the same webhook.

Same schema

Customer support

Handle inbound voice and SMS in one handler; resolve routine queries, escalate with context.

Voice + SMS

Appointment booking

Outbound dials confirm bookings; reschedule links go over SMS through the same SDK.

No lock-in

Where we draw the line

We handle voice. You keep your agent.

We handle the phone calls and the speech. You keep your prompt, your model, and your customer data.

Security & compliance

Enterprise-grade by default.

Audio is streamed, not stored. Data stays in your region, encrypted with your keys - and the open-source layers let you self-host the whole thing.

Data residency

Pin storage to US, EU or India regions - your choice, per project.

Encrypted end-to-end

TLS in transit, AES-256 at rest. Bring your own KMS keys.

Zero-retention audio

Streams aren’t stored by default. Opt in only if you need recordings.

Never trained on

Transcripts and recordings are never used to train any model.

FAQ

Questions before you start.

The products, the model, integration and security - the things developers ask before shipping.

SuperDialog is an open-source framework for writing realtime conversation logic - standalone and free. Unpod is the open-source CPaaS that embeds SuperDialog and adds the contact-center layer; you self-host it. The Developer Platform (unpod.dev) is the metered telephony + speech infrastructure those layers bill against - the only paid surface.

Build the agent. Ship the voice. Own the stack.

Start free with the open-source framework and CPaaS. Meter against Unpod infra only when you go live. No credit card to start.
