# Customize Call Treatment by Promo Number

> Give calls to a specific static promo number a different call treatment than the rest of the campaign.

If your Invoca campaign has more than one static promo number, you might want calls to different numbers to follow different call treatment options, even though they're part of the same campaign.

## Customizing a promo number's call treatment

1. Log in to your Invoca account. In the sidebar menu, click **Promo Numbers**, then select **Manage Promo Numbers**.
2. Find the number you want to customize.
3. In the Actions column, click the menu button, then select **Customize**.
4. Follow [Call Treatments & IVR](/s/article/call-treatments-ivr) to build a new call treatment for that promo number, then click **Save**.

The customized terms override the campaign's existing terms and conditions for that number. The Publisher hosting the promo number is automatically notified of the customization or blocking setting.
