Click2Call SDK

  • Updated on September 15, 2023

Click2Call feature provides a method for UCM630x users with a remote connect plan to embed a simple click2call link into their websites, to enable their web visitors to call live agents from their browsers by adding a shortcode into the web page source and configure a Call queue on the UCM to receive those calls.

Using the UCM630x/A Click2Call feature will help to connect the website visitors immediately to one of the available agents without dialing a number and without leaving the webpage by clicking on a customizable Click2Call icon.

This guide describes in detail how to configure the Click2Call feature on the UCM630x/UCM630xA series.
