Voice over Internet Protocol (VoIP) is a technology that allows users to make phone calls using the Internet instead of a traditional phone line. VoIP is also known as IP telephony.
VoIP enables voice calls to be transmitted as data packets, facilitating various methods of voice communication, including traditional applications like Skype, Microsoft Teams, Google Voice, and VoIP phones. Regular telephones can also be used for VoIP by connecting them to the Internet via analog telephone adapters (ATAs), which convert traditional telephone signals into digital data packets that can be transmitted over IP networks.
Integration of VoIP in Mobile Network
VoIP technology has been adapted for mobile networks, leading to the development of advanced systems designed to support voice communication over modern data infrastructures. Among these are Voice over LTE (VoLTE) and Voice over 5G (Vo5G), which enable voice communication over IP-based mobile infrastructures
