What is VoIP? The Definitive Guide to VoIP in 2023

Voice over Internet Protocol (VoIP) is a technology that transmits audio and video over the Internet. VoIP allows voice calls from smartphones, computers, WebRTC-enabled browsers, and special VoIP phones.

Both businesses and consumers can benefit from this technology since it typically includes additional features typical phone services do not possess. These features include custom caller ID, voicemail to email, and call recording. It is also helpful to organizations to unify communications.

VoIP Explained

VoIP works like a regular phone but uses an internet connection instead of a phone line. A group of technologies and methodologies enable it to deliver voice communications over the Internet. Among these technologies and methodologies are enterprise local area networks and wide area networks.

VoIP services convert audio signals into digital data, then transmitted over the internet. If a regular phone number makes a call, the phone number signal will be converted back into a telephone signal before reaching the other user.

VoIP can also handle outgoing and incoming calls routed through existing telephone networks. Some VoIP services, however, only work over a VoIP phone or computer.

Differences Between VoIP and Landline Phones

There are several considerable differences between VoIP and traditional landline phones. Check them below:

The Mechanism of VoIP

• Voice over Internet Protocol enables voice communication over IP-based networks like the Internet. A user’s VoIP phone connects to their Local Area Network (LAN) router or switches using an Ethernet cable or Wi-Fi.
• The VoIP phone reports information to the chosen VoIP provider’s server, including its unique identifier and the user’s account details.
• When the user initiates a call, the VoIP phone sends a call request to the VoIP provider, specifying the destination phone number or SIP address of the party being called.
• The VoIP provider establishes the call between the two parties by locating the recipient and creating a connection. The provider then exchanges voice data packets between the caller and the recipient.
• The recipient’s VoIP phone receives the voice data packets. It converts the digital signal into analog audio that users can hear using built-in speakers or external audio devices.
• Both parties’ VoIP phones continue exchanging voice data packets throughout the call, ensuring real-time, two-way communication.
