A non-VoIP (Voice over Internet Protocol) number refers to a traditional telephone number that is associated with a physical landline or mobile phone service provider. Unlike VoIP numbers, which utilize the internet to transmit voice calls, non-VoIP numbers rely on traditional telephone networks for communication.

Here are some key characteristics of non-VoIP numbers:

1. Physical Network Connection: Non-VoIP numbers are tied to physical infrastructure provided by traditional telecommunications carriers (e.g., AT&T, Verizon, T-Mobile).

2. Voice Quality: They typically offer clearer and more reliable voice quality compared to VoIP numbers, which can be affected by internet connectivity and bandwidth.

3. Regulation and Compliance: Non-VoIP numbers are subject to regulatory requirements governing traditional telecommunications services, including emergency services (911) access.

4. Usage: They are commonly used for personal and business phone lines, mobile phone services, and other applications where reliable voice communication is essential.

In contrast, VoIP numbers are virtual numbers that use the internet to transmit voice calls, often through services like Skype, Google Voice, or VoIP providers. VoIP numbers are popular for their flexibility, cost-effectiveness, and ability to integrate with digital communication tools.

When considering a non-VoIP number, it’s important to understand your specific communication needs, regulatory requirements, and the reliability of the service provider.
