VoIP: How it works & why businesses use it 

VoIP is a technology that allows voice communication and multimedia sessions to be transmitted over the internet instead of traditional telephone lines. It converts analog audio signals into digital data packets, which are then transmitted over the internet and reconverted into audio at the receiving end. VoIP relies on the Internet Protocol (IP) for data transmission, making it a cost-effective and flexible alternative to traditional landline phones.

A Telzio study found that those who switched to VoIP from a traditional phone line were able to reduce costs by up to 50%. Thus, more and more businesses of all sizes are now adopting this technology for its cost-efficiency benefits. It is also attributed to boosting productivity levels, thanks to its ability to integrate systems.
