📞Connect a Dapta-managed number

Buy a Dapta-managed phone number, assign it to a Voice Agent, and use it for inbound and outbound calls.

Use a Dapta-managed number when you want Dapta to handle the phone number and SIP trunk setup for you. This is the simplest path: buy the number in Dapta, assign it to an agent, then use it for inbound or outbound calls.

This is different from connecting your own Twilio account as a SIP trunk. If your company owns the Twilio account or wants calls to route through its own Twilio Elastic SIP Trunking setup, use the bring-your-own SIP trunk guide instead.

Step 5: Use the number for outbound calling.

When you place test calls, run campaigns, or use a Dapta Phone Call node, select the managed number anywhere Dapta asks for the calling number or From number.
