In certain situations using Invoca's legacy Web Integration Code (WIC), you can place a button on your landing page that, when clicked, prompts your customers to input their phone number. Then, Invoca will place a phone call to that customer. When they answer, they'll be connected to the call treatment for your Invoca campaign.
We call this feature "online click-to-call" — which shouldn't be confused with "mobile click-to-call", a different feature for mobile phone browsers that hyperlinks straight to the visitor's phone app.
Setting up an online click-to-call button on your landing page
Log in to Invoca. In the sidebar menu, click Settings. If you're a user on a network account, use the account switcher drop-down menu to select the Advertiser involved in the campaign you want to use with click-to-call.
In the Advertiser section of your Settings page, click Web Integration.
Click Advanced Tracking Settings, then scroll down to the Tracking Preferences section. Click the Display Format drop-down menu, then select Show online click-to-call button. When you're finished, click Update.
