Phone number masking
Protect customer & agent privacy with anonymous calling
Phone numbers are tightly tied to a person’s online identity and safety. The onus is on businesses to safeguard the privacy of their customers and workers. Use call masking to mask phone numbers and anonymize voice calls or texts, enabling user-to-user communication without revealing personal phone numbers.

A caller places a phone call to a recipient
Whether it's a customer, a third party or your organization's representative, calls can be initiated via standard dialing or via web or mobile app.
Anonymous phone calls are initiated in your Telnyx application
When the caller initially places the call from their device, they are automatically connected on their end of the call.
Recipient receives a call from a masked or customizable number
The recipient receives a phone call from the Telnyx core network, from a display number that's fully customizable within your Telnyx application.
Both ends of the call are bridged without numbers being revealed
When the recipient answers, Telnyx bridges the recipient's active call and the caller's active call together, allowing both parties to communicate with carrier-grade phone call audio, and without exposing either phone number to the other party.
