Any business can become more successful with happy and returning customers only when you implement good business ideas and follow great marketing plans. For this, you need to look for an easier way to connect with your customers to satisfy them with your services. 3CX Click-to-Call is a web-based communication that allows your website customers to enter their phone number and click on a button to initiate an immediate phone connection with your service. It is not only a free call for the customer, but is also a super easy way to request for a call. You can set the extension of your choice based on your requirement. With this feature on your website, you can expect better conversion rates, higher average orders and increased sales.

1.1. What is 3CX Click-To-Call?
3CX Click-to-Call is a 3CX/ PBX plugin that enables your customers to enter their phone number and immediately receive a phone call from your customer service department. For instance, if the web component is on the “support” page of the website, the call goes to the technical support queue, and if the web component is on the “Contact Us” page, the call goes to the sales queue. 3CX Click-To-Call can be integrated into your existing ASP.Net website. It requires only a few lines of code. Since 3CX Click-To-Call runs as a web service, you can run 3CX Click-To-Call from any server. Even if your website is hosted remotely, or is not running on windows (Apache and PHP for example) you can still use Click-To-Call by using an iframe. The web component occupies a small area of your screen and appears as shown below:

Step 4: Download the VoIPTools 3CX Relay (if required)
3CX permits one 3rd party application to communicate with the 3CX server at a time. To overcome this limitation, VoIPTools created the 3CX Relay Service. The Relay is a lightweight application that is installed directly on the 3CX server. The Relay exposes the 3CX Call Control API (and other VoIPTools services) to all our applications, and manages requests and events between by VoIPTools products and 3CX. The Relay also makes it possible to install our VoIPTools products on a remote server (including over the internet).

1. If you have not previously installed the Relay on your 3CX Server, you can download the Relay installer by clicking on the Download Relay button. The Relay must be installed directly on the 3CX server.

2. If you are installing 3CX Click-To-Call directly on the 3CX server, you can install the Relay simply by clicking the Install/ Upgrade Relay button and following the Relay install instructions.

If you have already installed the Relay, you need not install it again unless a newer version is required.

Step 5: Test the VoIPTools Relay Settings

1. In the Relay Type drop down, select Legacy Relay for old Relay or New Relay for new Relay based on the 3CX version of your application.
