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:
Phone number shown in agent card
Or in the header once you navigate to the agent’s page:
Phone number shown in agent header
You can also retrieve your phone number using the CLI. List all agents to see their phone numbers: 
cartesia agents ls
Or get detailed information for a specific agent: 
cartesia status <agent_id>
This returns agent information including name, deployments, and phone numbers.
