# CAI DNI Implementation Guide Supplement Click-to-Call Code Implementation

### **Overview**

This document serves as a supplement to the **Standard DNI Implementation Guide**. While the Standard Guide focuses on websites displaying non-clickable text phone numbers, this supplement addresses the specific requirements for implementing **Dynamic Number Insertion (DNI)** with **clickable text phone numbers**.

---

### **Who Should Read This**

This guide is intended for clients who display and utilize clickable phone numbers on their websites. These clickable numbers facilitate **click-to-call functionality** in two scenarios:

1. **Desktop Devices**: The clickable number initiates VOIP calls using services like Google Voice or Skype.
2. **Mobile Devices**: The clickable number pre-loads the phone number into the phone dialer or directly dials the number upon a click.

---

### **Getting Started**

Before proceeding, follow the instructions in **Section C.** of the Standard DNI Implementation Guide. Complete those steps exactly as outlined.

---

### **Supplemental Instructions**

#### **Section C. Step 2: Applying Class Elements**

For websites with click-to-call functionality, use the following updated examples for class elements and HTML formatting instead of the samples in the Standard DNI Implementation Guide:

### **Best Practices**

1. Always apply the correct class elements directly to the <a> tag containing the phone number.
2. Avoid nesting <span> or <div> tags unnecessarily within the clickable phone number’s HTML structure.
3. Ensure that the class is applied consistently for all phone numbers on the website.
