An IP phone is also called a VoIP phone. It utilizes Voice over IP technologies to place and transmit telephone calls over an IP network like the internet instead of a traditional PSTN or Public Switched Telephone Network. Your phone calls are routed over the internet or your LAN or Local Area Network. IP phones have many advantages over ordinary phones.
One is reducing your phone call costs since you no longer need to use the telephone network of your telephone service provider for making calls. Two, you are taking many technical advantages of using IP technology for telephony. To use an IP phone, just plug it in any available LAN port and it will automatically register at the VoIP phone system.
An IP phone behaves exactly as what an ordinary phone does. It also keeps its number. These are all made possible because of the SIP protocol. SIP is the short term used for Session Initiation Protocol. It is an IETF or Internet Engineering Task Force standard protocol for starting an interactive user session that includes multimedia elements like gaming, video, voice, virtual reality, and chat.
Similar to SMTP or HTTP, SIP operates in the Application layer of the OSI or the Open Systems Interconnection communications model. The Application layer is the level responsible for guaranteeing the possibility of communication. SIP can create internet telephony calls or multimedia sessions and then modify or terminate them.
