# Configure Enable Masking

The **Enable Masking** ensures that customer contact information, such as phone numbers, remains hidden from agents while still allowing seamless communication.

When masking is configured, agents can **send and receive messages, as well as initiate and receive calls**, without having access to the actual customer phone numbers. This helps maintain **data privacy while ensuring uninterrupted communication**.

If the **phone number field is secured (masked) in CRM using Column Security**, WhatsApp4Dynamics supports messaging and calling **without exposing the actual phone number**, provided that the **Enable Masking toggle is turned ON** in the configuration.

### Steps to Enable Masking

#### Step 1: Configure Masking in CRM

 1\.  Go to **CRM (Dynamics 365 / Power Apps)**

 2\.  Open the relevant entity (e.g., Contact / Lead)

 3\.  Apply **Column Security Profile** on phone number fields

4. Restrict access as required
