On the difference between ordinary telephone and IP telephone

Briefly describe the difference between ordinary telephone and IP telephone, and how to make IP telephone. What's the difference with ordinary telephones? 1, IP dialing is a shortcut, which generally appears in mobile phones, followed by computers and telephones.

The so-called IP dialing is to spread voice information by accessing data networks. For example, dial 1795 1 before making a long distance call. You can set the IP to 1795 1. Next time you make a long-distance call, just press IP to dial. The IP dialing key on the telephone computer is a shortcut key to quickly access the network with the support of the network! If it appears in a mobile phone, setting its IP dialing can also save money.

2. The purpose of 2.IP dialing is to transfer to other channels and reduce telephone charges and other uses.

Mobile 12593 also has a great discount for making international calls. GSM users, making local and provincial domestic calls, only need 0. 19 yuan or 0.29 yuan per minute; When making an inter-provincial call, it will be 0.39 yuan/minute. More importantly, for GSM users, they can enjoy making international calls all over the country (mainland excluding Hong Kong, Macao and Taiwan).

3. Mobile 1795 1, Unicom1791. It's cheaper to put this in front of the phone number when making a long distance call. If you have this key on your mobile phone, when you make a call, enter the long-distance phone number, just press that key to dial out, and it will automatically add IP.

To sum up, it is cheap to make long-distance calls, and IP phones do not need to be opened and do not need to spend extra money.

IP telephone is a new way of telephone communication through the Internet or other networks by using IP technology. With the increasing popularity of the Internet and the sharp increase in the number of cross-border communications, IP telephony has also been applied to long-distance telephone services.

Due to the intensification of competition among communication companies in major cities around the world and the loosening of telecommunications laws and regulations in various countries, IP telephony has also begun to be applied to fixed-line communications. Its main characteristics, such as low call cost, low construction cost, easy expansion and increasingly excellent call quality, are now regarded as a strong competitor of traditional telecom services by international telecom enterprises.

What's the difference between a 400 phone and an ordinary phone? 400 telephone is a shared service between the calling party and the called party, that is, the calling party bears the local telephone access fee and the called party bears all the incoming call answering fees. At present, it has been widely used in multi-industry pre-sales and after-sales service consultation. 400 telephones are divided into 4006 (China Unicom), 4007 (China Mobile's former Tietong), 4008 (China Telecom), 400 1 (China Mobile's new section), 4000 (China Unicom's new section) and 4009 (China Telecom's new section). The 400 telephone is a virtual phone switchboard designed for enterprises and institutions with unified numbers all over the country. All incoming calls to the 400 switchboard number are transferred to the preset fixed telephone, mobile phone or call center line. The 400 telephone switchboard is only responsible for handling incoming calls, not outgoing calls. Telephone charges are shared by enterprises and users who dial 400, and callers only pay local telephone charges. The 400 hotline embodies the sense of enterprise service and is a symbol of credibility and strength.

First, the most important point of 400 telephone is to establish a good image for the enterprise;

Second, the enterprise 400 phone will not be busy, which avoids the problem that the business phone is busy before;

Third, the calling/called party shares the payment, effectively eliminating malicious calls (800 number callers are free);

Fourth, self-management, convenient and fast, low cost, the number is carried for life, and the number is not changed.

The difference between ordinary telephone and satellite telephone is that voice signal is modulated into high-frequency digital signal and sent to the base station, and then connected to the called party through the exchange tandem office, and the called party demodulates the signal and restores it to voice. The call will be realized.

The satellite telephone is connected with the satellite network through the international public telephone network to realize communication.

Ip phone refitting ordinary phone ip phone can't be refitted into ordinary phone, which is different.

IP phone uses the network to transmit voice, and the network can be reused. Through network switching technology, multiple communication connections can be transmitted at the same time, which greatly reduces the cost, that is, it can be used by many people at the same time. Low cost.

The call between ordinary telephones needs the telephone exchange to establish a circuit connection, and after the telephone exchange establishes a virtual circuit, it is not used by others until you hang up, which is very expensive.

The difference between ordinary long-distance calls and ordinary IP calls is 0.7 yuan/minute.

IP is your IP access fee+local call fee. But+is cheaper than ordinary.

What's the difference between making an IP phone call and making an ordinary phone call? IP phone is the abbreviation of internet POTOCOL. IP telephone is a telephone service that is opened according to the network technical content stipulated by Internet protocol. Chinese translation is VoIP or VoIP. It uses the Internet as a sound transmission medium. So as to realize voice communication, a brand-new communication technology. Because of its low communication cost. So some people call it cheap mobile phone, VoIP, VoIP and so on. These are different names for IP phones. Actually, it basically means the same thing. Now the most widely used and scientific name is "IP phone". IP phone is an application that transmits voice information in real time through TCP/IP protocol on IP network. IP telephone started from PC-to-PC telephone on the Internet, and developed to connect the Internet with traditional telephone network through gateway, realizing IP telephone from ordinary telephone to ordinary telephone. IP telephone can be divided into four types: PC-PC, telephone -PC, PC- phone, telephone-phone and IP fax (real-time and store/forward). IP phone is a digital phone. Compared with the traditional analog telephone, the voice signal is digitally quantized, compressed and packaged before transmission, converted into a data stream with a bandwidth of 8kbps or less, and then sent to the network for transmission. The traditional analog telephone is transmitted by pure audio signal on the line. Because IP phone uses digital form as transmission medium, it occupies less resources, so the cost is very low and the price is cheap. At present, the voice quality of IP phone is not satisfactory compared with analog phone, but with the improvement of Internet connection speed and technology, the voice quality of IP phone will be further improved.

What is the principle of VoIP to ordinary telephone? It's simple. You know, when a phone call comes, the cat can surf the Internet. Similarly, the network cable can connect devices and call gateways, so you can connect telephone lines. As long as they exchange signals internally, we will not explore.

What's the difference between ordinary telephone and IP telephone? Ordinary telephone and IP telephone refer to the different signals transmitted by the equipment between the two offices, regardless of the connection mode.

Therefore, that connection mode is the same.

Why are IP phones cheaper than ordinary phones? Because IP phones use the network to transmit voice, the network can be reused, which means that many people can surf the Internet at the same time. Low cost.

Ordinary telephones need a telephone exchange to establish a circuit connection, and after the telephone exchange has established a virtual circuit, this line cannot be used by others until you hang up, which is very expensive.

IP (VoIP for short, from English VoiceoverInterProtocol；; Telephone is a new type of telephone communication, which uses IP technology through the Internet or other networks. With the increasing popularity of the Internet and the sharp increase in the number of cross-border communications, IP telephony has also been applied to long-distance telephone services.

Its main characteristics, such as low call cost, low construction cost, easy expansion and increasingly excellent call quality, are now regarded as a strong competitor of traditional telecom services by international telecom enterprises.

In the past, IP phones were mainly used in the intranet of large companies, and technicians could reuse the same network to provide data and voice services, which not only simplified management, but also improved productivity. IP telephone is a telephone service that is opened according to the network technical content stipulated by Internet protocol. Chinese translation is VoIP or VoIP, which simply means real-time voice transmission service through the Internet. It is a brand-new communication technology, which uses the Internet as the medium of voice transmission to realize voice communication. Because of its low communication cost (internet communication cost is 6 minutes and 6 cents per minute, while the international communication cost of ordinary telephone is more than one yuan per minute 10), some people call it cheap telephone.
