Click To Call by Elfsight is a widget, which makes it absolutely easy for your website users to dial your phone number without leaving the site. One click on the phone icon starts a call on mobile devices, and on PCs, it displays your phone number in the call window, where you can also display a photo of a communications person and a short text. For the most efficient widget work, you can choose separate pages where it will show, the type of visitors who could see it and an activating condition that will control its displaying.
