IP Voice, also known as Voice over Internet Protocol (VoIP), is a technology that allows voice calls to be delivered over Internet Protocol (IP) networks, such as the internet. Instead of using traditional landline service, IP Voice converts voice into small digital packets of information and sends them across the internet to their destination. At the other end, the digital data is converted back to an analog signal so that it can be heard through the handset. IP Voice can be used with a variety of devices, including VoIP phones, mobile applications, and web-based communications.

Some benefits of using IP Voice include cost savings, a wealth of new features, and the ability to make calls directly from a computer or special VoIP phone. However, it is important to note that a stable internet connection is necessary for good voice quality.

Overall, IP Voice is a useful technology that allows for voice communication over IP networks, providing a cost-effective and flexible alternative to traditional landline service.
