In this article we explain what Voice over Internet Protocol (VoIP) and Voice over IP (VoIP) are, how they work<\/strong>, the advantages and disadvantages<\/strong> of VoIP, what you need<\/strong> to use VoIP, and the types of IP phones available.<\/p>\n\n\n\n

1. IP TELEPHONY: WHAT IT IS<\/strong><\/h2>\n\n\n\n

IP telephony is a telephony that uses an Internet connection to make and receive calls.<\/strong> Today, in 2023, almost all businesses and individuals use VoIP.<\/p>\n\n\n\n

With VoIP, calls can be made from various devices connected to the Public Switched Telephone Network (PSTN) over the Internet to traditional phone numbers and also have a phone number.<\/p>\n\n\n\n

2. IP TELEPHONY: WHAT IT DOES<\/strong><\/h2>\n\n\n\n

IP telephony or ToIP (Telephony over Internet Protocol) is telephony where the voice signal is sent in the form of data packets over the Internet (Voice over IP) or a Virtual Private Network (VPN).<\/strong><\/p>\n\n\n\n

It uses the Internet Protocol<\/strong>, hence the abbreviation IP. VoIP operators are also interconnected with the traditional telephone network to enable communication between VoIP users and traditional telephony subscribers.<\/p>\n\n\n\n

This interconnection with the traditional telephone network allows calls to be made to traditional telephone numbers<\/strong>, such as geographical numbers, mobile numbers, nomadic numbers and\/or special rate numbers (902, 900, 800…)<\/a>; and to have a geographical number that any user can call.<\/p>\n\n\n\n

IP telephony is based on Voice over Internet Protocol (VoIP) technology, which converts voice into data packets so that they can be sent over the Internet.<\/p>\n\n\n\n
