What Are VoIP Phones and How Do They Work?

VoIP phones use the internet to transmit voice instead of traditional copper lines. The device converts speech into digital signals and sends them through a broadband connection. This process reduces call costs and increases flexibility.

Businesses choose VoIP phones because they lower call expenses, scale easily, and integrate with business software. According to Statista, companies save up to 60% on phone costs after switching to VoIP.

Key benefits include:

Lower costs: Internet-based calls avoid high tariffs.

Scalability: Adding new phones requires no extra cabling.

Mobility: Employees use the same number at office, home, or on the go.
