What does the error "your extension is not allowed to make outbound calls" mean?

Question

I am currently receiving the error message:

Your extension is not allowed to make outbound calls with browser currently, please contact your account representative for an upgrade.

What do I do?

Answer

This error usually occurs with our WebRTC-based clients, most commonly RingCentral Embeddable, a javascript embeddable web phone.

If you are using sandbox environment, you can add free digital line(phone) to your extension via the Admin Console. You will need to login using the sandbox user credentials.
