Voice over Internet Protocol (VoIP) is a technology that allows users to make and receive phone calls over the internet. It is a cost-effective alternative to traditional phone service, and it offers a number of advantages, including the ability to make calls from anywhere with an internet connection, the ability to use a variety of devices to make calls, and the ability to access a wider range of features, such as call forwarding and voicemail.
VoIP has become increasingly popular in recent years as the internet has become more widespread and reliable. Businesses are using VoIP to save money on their phone bills, and consumers are using it to stay connected with friends and family who live far away. VoIP is also being used to provide new and innovative services, such as video calling and unified communications.
