            What is IP Phone?

            Contrast to analog telephones, IP telephones are also called Internet telephones, VOIP telephones, SIP telephones, WiFi telephones, etc. ......

            The basic principle of IP telephony: IP telephony is a technology that uses the Internet as a transmission medium to achieve voice communication between computers and computers, analog phones and analog phones, and computers and analog phones. 
            The voice data is then packaged according to the TCP/IP standard and transmitted via TCP/IP protocol networks (including Internet, Intranet, ATM, Frame Relay, etc.) together with other types of data packets (data, email, video, pictures, etc.). 
            At the receiving end, these voice packets are reassembled, decompressed, decoded and converted into normal real-time voice for delivery to the final recipient via the PSTN.
