Hi, Sorry but we do not teach HTML here. But to get call link use:

<a href="tel:1234567">1234567</a>

OR

Inside Link field just: tel:1234567

Tips for beginners: https://www.w3docs.com/snippets/html/how-to-add-telephone-links-with-html.html

I want a pop-up button. or if you have a plug-in.

We have only Modal addon. But if you need more advanced extension please order/use very good -- Engage Box ( tassos.gr )

call button, I want from you. Help me please. your plugin archive.

Sorry I don't understand.

Please use Feature addon, it has all features of OLD Call to Action addon.
