Telephone-Links: ClickToCall over HTTP от Netas AG

This Add-On allows you to start a call with your IP-telephone which supports a HTTP-API when you click on any "tel"-link on a website.
On the configuration page of the Add-On, you have to specify URL, username and password of your IP-Phone. When you click on a tel-Link, the add-on sends a request to your phone to call the number.
