# Phone Numbers
Cartesia Telephony provides managed phone numbers so your agent can receive and make real phone calls without setting up your own telephony infrastructure.
## Provisioning
The platform automatically provisions a phone number for each agent when you promote to production. When an agent is deleted, the assigned phone number is released and cannot be re-assigned to another agent.
Bringing your own phone numbers or CCaaS provider is on the roadmap.
## Finding Your Phone Number
When viewing your Line agents from the Playground, you can see the provisioned phone number on the Agents page in the card:
Or in the header once you navigate to the agent's page:
You can also retrieve your phone number using the [CLI](/line/cli).
List all agents to see their phone numbers:
```bash theme={null}
cartesia agents ls
```
Or get detailed information for a specific agent:
```bash theme={null}
cartesia status
```
This returns agent information including name, deployments, and phone numbers.
