Anonymize and Secure Calls

By renting a virtual local number, businesses can use Number Masking as a bridge for their communication. Just let us know which number we should forward the incoming call or SMS to and we simply switch the CLI/senderId so the receiver only sees your virtual local number.

Check out our tutorial on how to add anonymous calling to your app.

Number Masking Features

Custom Prompts

Use our text-to-speech engine with support for multiple languages, or add pre-recorded voice files to further enhance the customer experience.

Number Handling

Regardless of whether you’re a local or a global company, you can reflect your local presence by renting local numbers – it’s all handled with ease in the Sinch Portal.

Recording

To further protect your customers, enable Call Recording and a sound file will be uploaded to your secure S3 bucket as soon as the call has ended.

Reporting

Download log files from the Sinch Portal, or fetch data instantly from our callbacks, to collect and store valuable call metadata for better analytics & BI.

Anti-Fraud

Maintain complete control of which calls you let through by responding to our callback sent on incoming calls.

Voice and SMS

Further protect the identities of your customers by enabling Number Masking on both voice calls and SMS.
