Building Voice Agents

Lindy supports two types of voice automation.

Inbound Call Handling — Uses the Call Received trigger to receive inbound calls. Best for teams looking to automate customer support, booking inquiries and lead qualification workflows.‍‍
Outbound Call Campaigns — Uses the Make Phone Call action to make outbound calls. Best for teams looking to automate sales outreach, consultation requests and other outbound campaigns.

How To Purchase a Phone Number

Lindy Phone Calls allows you to purchase a phone number without needing to bring an API key or outside app.

To purchase a number, add a Lindy Phone Call Received trigger or a Lindy Make Phone Call action.

Click the "Phone number from" field and select a number from the dropdown. You can start typing a number in the field to see similar, available phone numbers.

Each number costs $10/month and will be charged to the credit card on your Lindy account.

You can view your purchased phone numbers by clicking your user icon, selecting Settings, then Phone Numbers.

From there, you can Disconnect or Release the number from your account.
