# Customize Your Call Treatment by Publisher on a Performance Campaign

> Give callers from a specific Publisher a different call treatment than the rest of your campaign.

A call treatment is what a caller to one of your Invoca promo numbers experiences before connecting to a call center agent — including routing, voice prompts, and IVR menus. If you use Invoca for performance marketing, you may have more than one Publisher hosting your campaign's promo numbers on their landing pages.

If you want callers to experience a different call treatment depending on which Publisher they called from, use this guide. Keep in mind that a Publisher-specific call treatment overrides any call treatment options built for the campaign as a whole.

## Customizing your campaign's call treatment for each Publisher

1. Log in to your Invoca account. In the sidebar menu, select **Campaigns**, then **Manage Campaigns**.
2. Find the campaign whose call treatment you want to customize, then click the number in its Joined Publishers column to see the Publishers attached to it.
3. In Manage Publisher Campaigns, find the Publisher you want to customize, click **Actions**, then select **Customize**.
4. Follow [Call Treatments & IVR](/s/article/call-treatments-ivr) to build the custom call treatment, then click **Save**.

Once saved, the Publisher is automatically notified of their new call treatment.
