Note: If you do not want to display the phone number during an outgoing call, you can mask the number using a custom caller ID so that if the prospect or customer calls you back, they will be redirected to the dedicated support number.

To block numbers from making calls to your system, you need to create a blocklist.
Follow these steps:
Navigate to Setup > Channels > Telephony > Installed > Built-in > Details.
On the Built-In Telephony page, click the Telephony Groups tab.
Select Create Blocklist.
