VoIP Basics

What is VoIP?

VoIP, or Voice over IP, is a technology that transmits voice over IP (Internet Protocol) networks. Unlike traditional telephony, which uses physical phone lines, IP telephony makes it possible to place and receive calls over the Internet, and to do so using a variety of devices (smartphone, laptop or desktop, tablet, IP phone, etc.).

Voice calls undergo a series of transformations when placed with VoIP: the sound is transformed into electrical signals, converted into binary, scrambled, transmitted over the Internet, and reconstituted upon arrival. VoIP is an adaptable, customizable solution that multiplies telephony’s potential while reducing call costs. It’s an essential tool for companies, especially within departments that handle high call volumes (customer service, marketing, etc.).

What’s the difference between ToIP and VoIP?

VoIP makes it possible to transmit voice over any private or public IP network via a wired connection (ADSL, fiber optic) or a wireless one (Wi-Fi, mobile networks, etc.).

Although it’s based on VoIP, ToIP (Telephony over IP), only transmits voice over local IP networks (LAN).

What is hosted VoIP?

Hosted VoIP, or cloud VoIP, is an IP telephony solution available online and accessible via servers. It’s different from on-premise VoIP, which requires the installation of telephony infrastructure in the company’s local network.

Should I choose cloud VoIP or on-premise? It depends on what you’ll use it for.
