number masking solution

What is number masking?

Number masking or call masking is the best way for businesses to safeguard their customers’ identity, and prevent misuse of sensitive information, enabled by anonymization of customer’s phone number. This solution allows you to connect two parties without revealing either party’s phone number.

How It Works


Driver/Executive gets assigned to a customer

Clicking on the ‘call customer’ button in the app, automatically makes a call to Exotel’s virtual number.

Exotel reaches your server

Exotel pings your server with the driver’s/ executive’s details. Your server returns the corresponding customer’s number

Exotel Dials Customer Number

Exotel connects the assigned executive to the respective customer

Customer number masked

Customer/passenger numbers are masked from drivers/executives as virtual number acts as a bridge between the parties

How does pricing work for the voice calls?

Exotel charges voice calls on a per-leg basis:

2. Outbound calls - An Outbound call is a double-legged call ~ When an agent calls customer, Exotel first dials agent number and then dials the customer number to connect them over a virtual number.

Can I remove my business number from Truecaller's Spam list if I sign up for its Verified Business Caller ID?

The Verified Business Caller ID solution is not a spam removal solution rather is a brand

identity solution to ensure better identification, branding, and context to improve calling efficiency. It also helps prevent identity theft by scammers. The overall aim is to improve customer confidence and not to whitelist spam numbers. Crossing the spam threshold that is visible through an additional spam score tag on incoming call screens doesn't limit all the features offered as part of the solution.
