The WordPress click2call plugin will enable your WordPress site users users to call you directly. Clients, buyers, or shoppers no longer need to leave your website or even their computer to initiate a phone call.
There are settings to control the looks and feel of the click to call widget so that it can be aesthetically integrated into your site. This widget is powered by the Ribbit developer API.
Ribbit may charge for connected calls.
