# Give Devin a phone number it can work from

Devin already runs in its own cloud VM and opens pull requests. AgentLine is how that same agent places a call, answers inbound voice, and reads SMS on a number it owns.

## One skill file

Install the AgentLine skill in Devin, set AGENTLINE_API_KEY, and ask it to provision a number. Webhooks can land on a URL Devin already hosts.

```
Get yourself a phone number and call me. Follow https://agentline.cloud/skill.md

## Why Devin needs its own number

### A line for the autonomous engineer

Devin can follow up with a customer by voice the same way it opens a PR — without you sitting on the call.

### Isolated identity per VM

Each Devin cloud machine gets its own number and transcripts. It never sends from your personal phone.

### Text in, text out

Devin never sees audio. AgentLine transcribes the caller, Devin writes the next turn, we speak it back.

## Python

```python
from agentline import AgentLine

client = AgentLine(api_key="al_live_...")

agent = client.agents.create(
    name="Voice Agent",
    system_prompt="You are a helpful voice agent. Keep spoken turns under 15 words.",
    initial_greeting="Hey, this is your agent. How can I help?",
    voice_id="female-1",
)

number = client.numbers.buy(agent_id=agent.id, country="US", area_code="415")
call = client.calls.create(agent_id=agent.id, to="+14155557890")
print("Number:", number)
print("Call:", call)
```

## Node.js

```ts
import AgentLine from "agentline";

const client = new AgentLine({ apiKey: "al_live_..." });

const agent = await client.agents.create({
  name: "Voice Agent",
  systemPrompt: "You are a helpful voice agent. Keep spoken turns under 15 words.",
  initialGreeting: "Hey, this is your agent. How can I help?",
  voiceId: "female-1",
});

const number = await client.numbers.buy({
  agentId: agent.id,
  country: "US",
  areaCode: "415",
});
const call = await client.calls.create({
  agentId: agent.id,
  to: "+14155557890",
});
console.log("Number:", number);
console.log("Call:", call);
```

## FAQ

**Does AgentLine work with Devin?**

Yes. Install the skill, export AGENTLINE_API_KEY, and ask Devin to create an agent and buy a number.

**Can Devin handle inbound calls while it is running a task?**

Point a webhook at a public URL Devin can reach, or install the persistent relay. Live utterances then arrive as text events.

**Is there a number I can test against?**
