So far, the service has gone through seven stages: the first stage: as early as August 2003, some areas such as Shandong and Beijing launched the reservation service on fixed telephone and PHS; The second stage: Guangzhou Netcom launched the accompanying card. In March 2004, based on the accompanying card, it developed into an accompanying reservation service used on mobile phones. During this period, some areas in Shandong and Hainan implemented regional accompanying reservation service. The third stage: it entered the exploration stage from May to August, 2004, and initially launched the A card in Henan, Hebei, Jiangxi, Shandong and other places. The fee is: call the national mobile phone and open the fixed-line telephone in the networking area 1 cent/minute, and call the fixed-line telephone in other areas for 3 cents/minute (face value of 50 yuan 100 yuan, this card is a data card. From June to July, the development speed was very rapid, which attracted the attention of the national mobile operators. Media and communication management departments in Jiangxi, Shandong, Hebei and other places intervened. Because the landing problem is difficult to solve, the reservation number changes frequently during this period, and it is difficult to dial at 8- 10 peak in the evening. In July, information about related products on the Internet spread everywhere. According to statistics, there are 50 agents of all sizes. The organizers of this business are also under strong pressure from outside. From August 1 1 to August 20th, the business was interrupted for various reasons. During this period, the station was built and expanded, the technology was updated, and the scheme was re-formulated, thus forming the B card for fixed network charging. During this period, the complaints of customers and agents directly hit the company and Netcom customer service according to the feedback from the customer service center. The fourth stage is from the end of August to the present. Shenzhen Netcom obtained the authorization of relevant departments on the C card, so it suspended the B card and promoted the C card. During this period, many agents asked customer service for B cards, with a gap of more than 20,000. It is in this "green and yellow" period that various places have established or will soon establish "reservation" platforms, including Shenyang, Inner Mongolia, Shandong, Zhejiang, Jiangsu, Yunnan and other places. In addition to Netcom, Tietong has also indicated its intention, showing that a single spark can start a prairie fire. No matter where the booking platform is built, the market will be organized uniformly, and those with strong performance will have more market opportunities. The combination of Shandong-Shenyang-Guangzhou has fully demonstrated this trend. At present, the northern platform has been successfully built and has entered the account opening. After several months of technical and market summary, the northern platform is relatively perfect, and the policy of making an appointment without charge has been realized. At present, North Card (Changtong Card) has become the mainstream product of reservation card in the market. The fifth stage is 165438+20041early October. Shenzhen Tietong Reservation Card was officially launched. The latest selling point of "Yitong Card"! Reservations are free. E-pass card has replaced all the A\B\C cards in the western network. Shandong Netcom and Shenyang Netcom are both powerful operators in China, and they are the only reserved equipment providers in Guangzhou (also reserved equipment providers for ABC cards). Powerful operators and equipment suppliers, together with three strong players, launched the "Yitong Card" of Northern Netcom. Really realize the free reservation, ringing is not busy, and display the local phone number. It is the only reservation service launched by operators at present, and it is also the cheapest reservation service on the market. In the future, according to the increase of customers, we will continue to expand in cities in the southern region, and it is estimated that we will develop 2 million customers. In the sixth stage, Shenzhen Tietong reserved cards for sale, and the previous operators followed suit and made a comeback. In this way, the current booking business is more stable and diversified, and each operator has its own advantages. It will be officially integrated on June 5438+1 October1day, 2005, and the E-Pass card has opened the international long-distance function. The merger of various cards of other booking services will represent the unification of booking services. At present, the mainstream products are long-distance mobile phone cards (mainly physical cards, 300 yuan face value, display phone numbers, and can make international calls, and the system charges 0.30 yuan per minute), portable mobile phone cards (mainly data cards, temporarily 30 yuan face value, and the system charges 9 minutes per minute during the day), and mobile phones can be recharged at will (the system charges 0.30 yuan per minute, which is more convenient and stable). In 2005, E-Pass card and smart card were also introduced one after another, and China's accompanying reservation card created the lowest international and domestic long distance in China. All kinds of reservation cards on your mobile phone let you call whenever you want. The seventh stage is how to use the callback card at this stage-only 1 gross per minute. Mr. Chen's mobile phone has been turned on for "Super Listening", and 20 yuan can answer 1000 minutes a month, but the mobile phone is still 40 cents per minute. Because the mobile package can't be enjoyed at the same time, Mr. Chen still thinks that the mobile phone fee is not cheap after half a day's calculation. Hearing from colleagues that the postal currency card market sells "callback cards", Mr. Chen Can could not help but be moved. How to discount the callback card? Vendors in the postal currency card market gave reporters a popular example. Zhang San is in China, Li Si is in the United States, and Zhang San should be called Li Si. Zhang Sanyi dialed the number and Li Si's phone rang. Li Si said, Hang up and I'll call you back. It's too expensive for you to call. This is the callback card, and the platform to ensure the realization of this function is the VoIP that everyone often says. The phone bill of the "callback card" was deducted from the card, and the reporter did not understand. The stall owner took out a "callback card" and patiently said, first bind the card number and password of the "callback card" to your mobile phone, then you dial the reservation number (for example, 1390 998888), and the phone will hang up automatically after dialing, and the "callback card" system will call you. Then you can dial the number you need, and the reservation number of the system will be displayed on the other party's mobile phone (for example,/kloc-0 13909998888) instead of your mobile phone number. Because your mobile phone is "super-listening", it is free to answer the phone within the specified time, and you only pay the card fee of "callback card". The "dial card" charges 1 cent per minute, which is only 1 cent per minute, which is very cheap for long-distance or local calls. But the stall owner said that it is not possible to make international calls yet. It is understood that users who often use "callback cards" are mobile phone users. Mr. Hu, who works in an advertising company, said that he held a super hearing for 20 yuan, and it was enough to answer the phone with a "callback card" for 2000 minutes a month. It was also very cheap to call every minute 1 cent. When the reporter asked him if it was troublesome to dial several numbers with this phone, Mr. Hu said that it was no trouble. I saved the reservation number in the phone book and named it "April", which ranked first in the phone book. Just pick up the phone and dial. The stall owner said that since the announcement of the preferential packages of China Mobile and China Unicom, the "callback card" has sold better than before, especially the card market is dominated by wholesale. "Is this card allowed to be sold in China?" The reporter asked. The stall owner said with a smile, isn't it normal to spend money on calling cards and the "callback card" company provides you with call service and get paid? According to a professional, the working principle of the "callback card" currently sold in the market is actually to use the difference between the current calling fee and the called fee, realize the change of call flow through the flexibility and openness of softswitch technology and the convenience provided by value-added services, and use the network of existing operators to achieve the purpose of saving telephone charges for users. Calling users can turn themselves into called users through softswitch networks, while operators or virtual operator can make profits by charging lower tariffs. According to informed sources, the current "callback card" business is mainly done by some small operators. They buy equipment and charge users relatively low telephone charges. Then they use the characteristics of fixed telephone, PHS and some mobile phones to receive free calls, transmit voice packets through the network, and then connect the signals to some rented public telecommunication networks to realize the call function. Highlight: Dial-back card-an alternative single charge. Recommended index: ★★★★★★★★ The five-star telecommunications service called "dial card" is said to be very cheap. An international call from home to the United States costs about 70 cents per minute, and the domestic call is as low as 0.09 yuan per minute. At present, this telecom card business called "callback card" has been widely traded on the Internet. Since July, its expansion has accelerated rapidly. At present, there is no clear definition of VoIP in China. Calling back is surprisingly cheap. An American telecommunications company called eCallchina is providing international callback service in China. This company was founded in June, 20001,and is a member of the American business organization Better BusinessBureau. According to the information provided by this company, when users need to make international calls, they can use the following methods for international telephone communication, with almost negligible cost and relatively stable call quality. Domestic users need to dial the company access number 01331* * 877 or 01331* * 866 (this is the ordinary China mobile phone number), and the system will hang up automatically after ringing for three times. The user needs to hang up first, and the user's phone will ring automatically after a few seconds. Users only need to choose the language type (Chinese or English) according to the prompt, and then enter the phone card password and the phone numbers of foreign relatives and friends. In a few seconds, the international call will be connected. When users make international long-distance calls in China, they are actually using the domestic telephone system in the United States, and the fees to be paid are also the local tariff level in the United States. Moreover, compared with the domestic high-level international long-distance charges, the price of this callback card is still very attractive. According to the reporter's investigation, some calling cards on the market are often limited to calls between some large and medium-sized cities and developed areas, and this callback card can be used without barriers in any part of China (including Hongkong and Taiwan Province Province). Users can dial from any program-controlled telephone in China. The only restriction is that users can't use it on extensions and smart phones. Mr. Zhu, a mobile phone callback card in Beijing, just registered a company in April this year, specializing in the sales of callback cards. "My main customers now are not individuals, but enterprise users, including companies with large telephone bills such as foreign trade, logistics and sales. A company's monthly phone bill ranges from four or five hundred to several thousand. " In less than half a year, Mr. Zhu's company has grown from four employees at the beginning to nearly 20 employees at present, covering the national market. According to him, his company's monthly turnover can reach more than 5 million yuan at present. The reporter found that there is also a mobile phone dialing card in the Beijing market, which is actually a technical variant based on VoIP. Dial-back cards are used to call back both parties through the system, so that one-way charging mobile phone users do not generate call charges when making local calls, and users only need to pay 0. 1 yuan/minute for this purpose. Now some electronic goods stores and residential quarters have been peddled by salesmen, with a face value of 50 yuan, 100 yuan, and 200 yuan. You can get a 15% discount for wholesale or purchase. However, the user must pay the same face value in advance. A person in charge of the marketing department of Telecommunications Research Institute of the Ministry of Information Industry revealed that in recent years, the loss of international long-distance calls caused by VoIP in China is not less than 654.38 billion yuan/month, and the monthly loss of Guangdong Telecom alone exceeds 30 million yuan. However, because there is still no clear definition of VoIP in China, although operators are forbidden to launch related services, some domestic ISPs have attacked this emerging market on a large scale after seeing this market. According to incomplete statistics, at present, there are at least the following VoIP network phones in China: etalk and Gtalk issued by foreign network operators, Web cards, heartthrobs and E cards issued by domestic telecom operators, and so on. He said that with the rapid upgrading of IP phones and the fierce impact of VoIP services, the domestic long-distance telephone market, which has been seriously shrinking, is suffering a loss of one billion yuan every year. Experts remind: It is best to use regular telephone service. The insiders believe that in the current calling card market, the callback card business lacks vitality. In order to prevent these irregular dealers from providing telecommunications services after receiving money, users have nowhere to complain. An expert from the Telecommunications Research Institute of the Ministry of Information Industry suggested that consumers had better choose telephone services provided by regular operators. At present, calling long-distance calls such as 17909 and 96446 on the market do not need to be prepaid, and call records can be inquired at any time, which is a relatively stable long-distance card service in China. Note: Telecom "callback card" information comes from public information published on the Internet. The copy of this site is only for friends to buy telecom "callback cards" for reference, and it does not involve profit. Related businesses operating telecom "callback cards" can also come to the website to post more promotional information about telecom "callback cards" for free. Dial-up cards Dial-up cards, similar to long-distance IP and 200 cards, also have account numbers and passwords. Deduct the phone bill in the card during the call. Some IP cards offer a discount of 10 cents per minute, but you need to know that dialing an IP card requires a basic phone bill, so in fact, you use an IP card to make long-distance calls. It is estimated that the fee you pay is from 0.3 yuan to 0.7 yuan every minute, and you don't need an IP card to make local calls. Call card reservation, because of the particularity of the service, the calling party is also in the answering state. As long as it is a one-way charging mobile phone, the basic phone bill is 0. Then use the reserved callback card to make a phone call, no matter long distance or local call, as long as 10 cents per minute. The principle of callback firstly, the user dials the access code of the callback platform. After receiving the user's calling number, the platform actively hangs up the connection or manually hangs up, and calls back to the user's phone as an operator (actually the first calling party) within 3 seconds. After the user picks up the phone, the first call link is established (at this time, neither party has any phone bill), the system plays a prompt tone, and the user dials the called number (the real called party). After receiving the called number, the callback platform initiates the second call and plays the corresponding prompt tone to the user. If the called party goes off-hook, a second link is established. At the same time, the callback platform connects two links, and the caller and the called party establish a call. After the call is completed, the system records the bill generated in the second link and deducts it from the user's account according to the corresponding rate. When roaming in other places, you can answer the free phone number around you, edit the short message "Phone Number #" with your mobile phone and send it to139 * * * * * * *, and the system will automatically reply the phone to the number you specify, and press the prompt tone after answering. Charge: 0. 10 yuan/min, plus SMS fee 1 jiao each time. 1. Applicable object: 1, all mobile phone users who answer long-distance fixed calls for free; 2. It can only be used if the called party is free (cell phone answering is generally not free when roaming, so the service cannot be used).

Second, the dialing method 1. Call the "reservation number" through mobile phone, landline and PHS. 2.

At this time, the server acquisition system has collected your calling number. After 3.2-5 seconds, the server will call your mobile phone, PHS and landline. 4. When you answer the phone, you will hear a voice prompt and follow the voice prompt; Enter the called number you want to dial according to the dialing rules, and press "#" to end. At this time, the server receives the called number for the second time and connects you. 5. Waiting for the answer, the called party picks up the phone and the two sides talk.
