This allows you to place a call via a url. This is typically used with FreePBX with a Call.php script
This allows you to link TEL: links with a URL.
This is often used with FreePBX servers with a Call.php extension. For example I use this to connect my local PBX server to my computer. When I want to call a user or a company I just click their phone number and it links to my desk phone.
If you have a FreePBX server and want to add a way to click to make calls this is the plugin for you. I am sure it will work with other providers as well, I am just not familiar with them.
