In the world of Voice over Internet Protocol (VoIP) communication, ensuring privacy and security is paramount. Two terms that often come up in this context are N-CLI and CLIR. Understanding these terms and how they work is essential for businesses looking to safeguard their communication channels. In this guide, we'll explore what N-CLI and CLIR are, how they work, and how you can get N-CLI in India.

What is N-CLI and How does N-CLI work?

N-CLI stands for Non-CLI, which stands for Non-Caller Line Identification. In simple terms, N-CLI allows businesses to make calls without revealing their actual phone number. Instead, a generic or masked number is displayed on the recipient's caller ID.

N-CLI works by substituting the actual caller ID with a different number. This number can be a generic company number or a specially assigned virtual number. When a call is placed using N-CLI, the recipient sees this substituted number on their caller ID instead of the caller's actual number. This helps businesses maintain privacy and confidentiality while communicating with clients or customers.

What is CLIR?

CLIR stands for Calling Line Identification Restriction. It is the opposite of N-CLI. Instead of hiding the caller's number, CLIR allows callers to restrict the display of their number on the recipient's caller ID. When CLIR is enabled, the recipient sees "Private Number" or "Unknown Caller" on their caller ID instead of the actual number, To get CLIR service in India, businesses can contact DULTR TECHNOLOGIES.
