2. ### 2Sign in

3. ### 3Ask
   
   Mention Speko in the chat, or pick it from the tools menu. Calls from ChatGPT stop at five minutes unless you ask for a longer limit.

## What ChatGPT can do

- Place outbound calls with an agent you deployed
- Run test calls and play back the recording in the chat
- Generate speech, with an inline audio player
- Read agents, calls and transcripts
- Search the Speko docs

## Not from ChatGPT

- Buy phone numbers
- Read credits and usage

OpenAI's directory rules on selling digital goods keep provisioning and billing reads off the ChatGPT host. Do those in the console.

## Questions

**Can ChatGPT make phone calls?**

Yes, through Speko. With the Speko app connected, ChatGPT can place an outbound call with a voice agent you deployed on Speko, and read back the transcript.

**How long can a call from ChatGPT run?**

Five minutes by default. Ask for a different limit and the call is placed with it.

**Does the other person know it's an AI?**

Yes. Every call placed from a directory host starts with the AI disclosure, injected on the server, and the agent cannot be prompted out of it.

**How does it sign in?**

OAuth in the browser: the client opens Speko's sign-in, you approve, and it gets a token bound to the MCP endpoint. For automation, send a Speko API key as a Bearer token instead.

**What does it cost?**

The MCP server is free to connect. Calls and agent minutes bill at the published rates on the pricing page, and every account starts with $10 in credit.
