Call a permanent free contact with the phone use evaluation

Today's small series for everyone to bring the use of the phone evaluation. Since there is not much competition in the domestic telecommunications industry, at the same time, per capita income level is not high, resulting in the telephone charges have become common people and telecommunications operators of the general contradictions, while the common people complain that the telephone fees are too expensive to use, while the operators count the money every day also said they make ends meet. So in the arduous struggle, the wise masses came up with one more solution to deal with the problem of high telecommunications tariffs, the most fire is the free telephone. A number of companies doing free telephone business in China, like many dozen, there are letters, 66call and so on are dabbling in it, and in the first two days, the contact treasure also announced into the free telephone field, in addition to the former Contact Treasure Dial assistant renamed as a touch of the treasure phone, but also the main promotional points for the product for permanent free, How much difference does it have with the free phone software that is already available? Let's take a dip today. In fact, say free call, rather than a more real name-network telephone. Perhaps the concept of domestic Internet telephony has not yet been accepted by many, but if it comes to Skype I'm afraid a lot of people have heard that Skype's success in overseas markets has led many people to see the business, and a similar business is emerging domestically. But most internet phones, despite their free banner, but in fact more profitable way is to rely on the user recharge, such as the famous Skype, users through Skype dial a network phone, connected to receive the connection fee, and call every minute to charge a certain fee, although the cost relative to the traditional telephone is much lower, But actually the user still has to pay for it. and the contact treasure in the call of the treasure in the promotion of permanent free look like a grab some of the colleagues, but actually this bowl of free lunch delicious? You can only pass the test to find out. At present, the contact phone is still in the sealing period, I got two activation code through a friend, activated two mobile phones, the current touch of the phone has only the Android end of the application, the iOS end involves calling the underlying permissions of the phone is still in development. The layout of the software has not changed, after installation, the dial will still replace the system's native dialing function, while the main push of the free phone function is not marked, only in the dial or the upper right corner of the more options to find, hidden position of deep how to look like a main function. Of course, you can understand that the touch of the treasure is not willing to break the user's habits before, but the new features do let me a good find. The option to dial the toll-free number is integrated into the dialing keys, and since the toll-free calls need to be based on the network, the free phone button will only light up if there is a network. So here's the problem! In the absence of a network, the button will still exist, but it is gray, it is very awkward, because it will affect my normal use, can the siege lions to touch the treasure of this function in the absence of network environment to remove it? At present, the free phone number provided by the contact can be reached between the mobile phone of twoOK, the caller needs to call in WiFi or 3G/4G network environment, and the callee can answer the phone if there is no network environment. This undoubtedly greatly increases the use of the free phone scene, basically as long as there is a network of places can use this function. According to the test, the current network phone is no time billing mechanism, it will not be like a lot of software to limit the length of the call, in other words, if you have a small partner in the United States, then you through this feature to call the foreign phone is also free. The only thing that can interfere with you is the network environment. In the test I found that the contact network of the network is a very high degree of reliance on the Internet environment, I tested several environments, the following to carry out the disk: 1. Two mobile phones in the same WiFi environment, the network quality is good. The main call and called call the quality of the call is quite good, no voice delay, can hardly hear echoes, call quality comparable to the traditional telephone. 2. Two mobile phones in different WiFi environment, the network quality is good. The call and call calls are of a very good quality, with almost no voice delay and echoes, and the quality of the calls can be comparable to traditional telephones. 3. The main call mobile phone in the WiFi environment, called Mobile phone in China Mobile 4G network environment, the latter signal full lattice. Call the call the quality of the call is good, the call will appear in less than 1 seconds delay, almost no echo, belong to the normal acceptable situation. 4. The main call mobile phone in China Unicom 3G network environment, network signal full lattice, called mobile phone in the WiFi mode, the network signal is good. The main call calls the quality general, appeared the slight echo condition, is called the square call Normal, the delay is not obvious. 5. The main is called in the mobile network environment, the signal full lattice. The main call cell phone quality is good, relatively clear, delay is not obvious, slight echo, belong to acceptable range. 6. The main call in the WiFi environment, the signal is good, called Telephone no network. The main call cell phone call quality is clear, is called the phone voice compared to a little before, there is a slight delay, there is no echo. 7. The main call in China Unicom 3G network environment, signal full grid, called Telephone no network. The main call calls the quality of general, there has been a slight echo, called the phone appears about 1 seconds of delay. Basically, these 7 tests cover everyday use not black not to blow the talk, the telephone network call no official blowing so perfect, will also be in part of the environment of delay and echo of the situation, which in the current network phone is a common problem, Skype can not do to perfect the elimination of echoes and delay. However, in the entire test, the good point is that there is no even one disconnection problem, while the delay and echo are within the acceptable range, and does not affect the quality of the call.
