Import a number

Import phone numbers to use for inbound and outbound calls with your deployed agents. Currently, Agent Studio supports importing numbers from Twilio's Elastic SIP Trunk.

What is Elastic SIP Trunk?​

Elastic SIP Trunk is the connection layer between traditional phone networks and Studio. When a caller dials your phone number, their carrier routes the call over the public telephone network. Elastic SIP Trunk translates that call into a format Studio can process, and passes it to your configured agent.

The "elastic" part means the trunk scales automatically with call volume; the same configuration handles one call or thousands without any changes on your end.

Studio currently supports Elastic SIP Trunk integration with Twilio. Support for additional providers is planned.

Prerequisites​

  • An active Twilio account with Elastic SIP Trunk configured. See Set up SIP trunk.
  • A deployed agent in Agent Studio
  • A phone number configured in your Twilio SIP trunk
  • SIP domain and credentials from your Twilio account
