Intel XDK - Soft Phone App

Question

I developed an application with Intel XDK for internal use on local network, which is responsible for listing all the company extensions, I would like to implement in the click of the list items the functionality of linking to the extension, using SIP technology - Session Initiation Protocol.

In short, the user clicks on the list item and the application connects to the extension

I found references on the Internet, but the documentation didn’t help me much.

References of SIP technology;
