# Voice Integrity Onboarding in the Twilio Console

## Register your Phone Numbers to protect legitimate calls from getting mislabeled as spam

In a few clicks in the Console, you can enable Voice integrity on your Twilio Phone Numbers.

> \[!NOTE]
>
> You are considered a **direct** customer if your employees are responsible for making the calls. This includes BPOs.
>
> You are considered an **ISV** (independent software vendor) if your customers are responsible for making the calls using your product.
>
> For ISVs, there is a [REST API](/docs/voice/trusted-calling-with-shakenstir/shakenstir-onboarding#shakenstir-onboarding-with-the-trust-hub-rest-api) available to allow you to pass your customer's business information directly to Twilio to get vetted.
