What does ip phone mean?

The so-called IP phone refers to the phone technology that uses VoIp (Voice over IP) technology to transmit voice.

For example, the sound emitted by A is converted into a form called a data packet for transmission, and restored to voice data at B. This sequence of "data packet conversion, transmission, and restoration" is performed based on VoIp technology.

To convert speech into data packets and back to speech again, software must be used. The software is embedded in IP phones, IP phone adapters, and IP phone programs on PCs.

As mentioned above, IP telephones are cheaper than ordinary telephones, although calls are made through unprecedented processing methods such as packet conversion and recovery. This is because the network used to transmit data packets (the IP network) requires less expensive equipment than legacy phones.

The cost of setting up and managing the relay network is very low, which is different from the original ordinary telephone. This is the secret of the low price of IP telephone.

If it is transmitted in a different way than in the past, the most worrying thing is the quality of service. "Cheap but poor quality" cannot be used for company business. Many people pointed out that "transmission through the Internet is an unguaranteed network, so they are skeptical about the quality of service."

However, IP telephony is not the same as Internet telephony. The IP network transmitting data packets does not necessarily have to be the Internet. Many IP telephony services use private IP networks.

The so-called IP address is actually a network address stipulated by TCP/IP theory. A simple understanding can be thought of as your house number on the network. TCP/IP (abbreviation for Transmission Control Protocol/Internet Protocol, Chinese translation is Transmission Control Protocol/Internet Protocol) protocol is the most basic protocol of the Internet. Simply put, it is composed of the underlying IP protocol and TCP protocol. TCP/IP is an internationally accepted network protocol and the first set of protocols used on the Internet. It is precisely because of the TCP/IP standard that computers and other devices around the world can be connected to the Internet and access each other and communicate with each other.

Before the Internet was formed, many small networks had been established in various places, called local area networks. The Chinese meaning of Internet is "Internet". It is actually formed by linking local area networks around the world. A "network that can be linked to each other (i.e. the Internet)". However, various local area networks before linking have different network structures and data transmission rules. After linking these small networks, what kind of rules should be used to transmit data between the networks? It's like there are many countries in the world, and people in each country speak their own languages. How can any two people in the world communicate with each other? If people all over the world could speak the same language (i.e. Esperanto), wouldn't this problem be solved? The TCP/IP protocol is the "Esperanto" of the Internet. The IP address is the "house number" stipulated in the TCP/IP protocol. For example, Shenzhen Litong sells IP phones.
