IP telephony

IP telephony stands for "Internet Protocol telephony." It's a way to talk to people using a telephone, but instead of using traditional telephone lines, it uses the internet to make the call. It's like talking on the phone but using the internet instead of your regular phone line.

Here's an example: Imagine you and your friend are playing a game online, and you want to talk to each other while you play. You can use IP telephony to connect to each other and talk through your computers' microphones and speakers.

IP telephony can also be used in a business setting, where it can be called "VoIP," or "Voice over Internet Protocol." This means that instead of having a traditional phone on your desk, you might have a special phone that connects to the internet instead of your phone line. This can save money because it can use the same internet connection as your computer, instead of paying for a separate phone line.

Overall, IP telephony is a way to talk to people using the internet instead of traditional phone lines. It can be used for personal conversations or in a business setting, and can save money by using the same internet connection as your computer.
