The tenfold Chrome extension parses every page looking for phone numbers and turns them into click-to-dial links. You can control what numbers are recognized by setting your click-to-dial country codes in the admin dashboard.
It is possible you’ll find text marked up for click-to-dial, but you need the original link or text. In this case, just toggle the click-to-dial button under “Settings” in the Chrome Extension as shown below.
Disabling click-to-dial, you will continue to see call popups for any inbound or outbound calls.
