IP telephony, also known as VoIP (Voice over Internet Protocol), is a technology that allows users to make and receive phone calls over the internet. It is a cost-effective alternative to traditional landline phone services, 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 and services.
IP telephony is becoming increasingly popular as businesses and consumers look for ways to save money on their phone bills. It is also becoming more widely available, as more and more internet service providers offer VoIP services. As a result, IP telephony is likely to continue to grow in popularity in the years to come.
