# Automated Dialing from Your Landing Pages Using Online Click-to-Call

> For WIC accounts, add a button that prompts a visitor for their number, then have Invoca call them and connect them to your call treatment.

For accounts using Invoca's legacy Web Integration Code (WIC), you can place a button on your landing page that prompts visitors to enter their phone number when clicked. Invoca then places a call to that visitor — when they answer, they're connected to your Invoca campaign's call treatment.

This feature, "online click-to-call," is different from "mobile click-to-call," which hyperlinks directly to a mobile visitor's phone app instead.

## Setting up an online click-to-call button

1. Log in to Invoca. In the sidebar menu, click **Settings**. If you're on a network account, use the account switcher dropdown to select the Advertiser tied to the campaign you want to use.
2. In the Advertiser section of Settings, click **Web Integration**.
3. Click **Advanced Tracking Settings**, then scroll to the Tracking Preferences section. In the Display Format dropdown, select **Show online click-to-call button**, then click **Update**.
4. Finish setting up your WIC deployment by following [How to Deploy Invoca on an Advertiser's Landing Page for Affiliate Marketing Using Invoca Web Integration Code (WIC)](/s/article/deploy-wic-advertiser-landing-page). That article also covers customizing your click-to-call button further using the `ctcButtonContent` parameter.

Once your WIC code is set up and your landing page is live, visitors will see your click-to-call button as part of your display ad.
