Which VoIP phone works well?

Abstract: With the development of mobile phone network, many VoIP phones appear in Android and Apple stores at the same time, and some of them also slogan that VoIP phones are always free. Which VoIP phone works well? The following small series selects WeChat phone book, TouchPal phone, 360 toll-free phone, Yixin phone and Xinyou for comparison. Let's take a look. Comparison between VoIP software and VoIP software.

With the comprehensive coverage of domestic 4G networks, more and more previously unimaginable functions have been realized. In the past, we contacted our friends by phone through the 2G network, which is by far the most common communication method, but the voice cost can not be ignored. Nowadays, VoIP has become a new trend, which has gradually replaced the traditional telephone.

Seeing this good development prospect, many domestic application manufacturers began to exert their efforts in this respect, and successively launched free calling software on mobile phone platforms. The application market is full of all kinds of free calling software for a time, so the question is, which of these free network calling software is better to use? Let's take a look!

What are the VoIP software?

In the application market of Android platform, we selected five relatively mainstream free calling software, namely WeChat phone book, TouchPal phone, 360 free phone, Yixin phone and Xinyou. Let me first introduce these five free calling software:

Wechat phone:

WeChat phone book is a communication enhancement software created by Tencent: it supports the import of WeChat avatar; Support automatic filing of notification SMS, spam SMS interception and SMS collection &; Intelligent management such as encryption; There are also call attribution, blacklist, automatic backup of contacts, and identification of strange numbers. At the same time, it supports free calls under network conditions, and turns audio into voice mail when the other party can't connect. Currently supports Android and iOS versions.

Touchpal phone:

TouchPal mobile phone is a multifunctional communication assistant App. On June 20 14, 10, TouchPal added a free phone function, which is also the first "truly free" free phone product in China. Its biggest feature is clear sound quality, no echo and no noise. At the same time, there is no in-house purchase, no advertisement, and it is free forever. You don't need to register. After installation, you can make free calls under WIFI and 3/4G. The other party can talk without installation or networking.

In addition, TouchPal phone supports unfamiliar caller identification, harassing calls, spam message interception, intelligent grouping and intelligent dialing. Of course, users can also send WeChat from the address book, which can completely replace the system dialing, and is called a new communication method instead of typing and chatting.

360 toll-free number:

360 toll-free telephone, mainly permanent toll-free, can also be registered. The software has the function of security and anti-harassment, and can well identify and intercept strange numbers after opening; After installation, you can call any mobile phone or landline for free, even if the other party does not need to install it.

CreditEase Tel:

The software, jointly developed by Netease and Telecom, focuses on high-definition voice chat, and has the functions of free massive expression mapping, free text messages and telephone messages, making communication more interesting. At the same time, it has many bright features such as multi-person telephone and international roaming telephone.

Have a letter:

Free phone with letters is a new generation of free internet phone software, which can make free calls to national mobile phones and landlines when there is a network. Support Apple's ios, Android, Symbian system and Android mobile phone tablet. Support sending messages to display numbers, automatically identify friends when there is a letter, and enjoy HD unlimited free calls and free short messages anytime and anywhere.

Well, we have a preliminary understanding of these five softwares. Now let's do a detailed comparative test to see who is better among them through several major items.

Which VoIP phone works well?

Login Mode/Free Call Duration/Call Practicality

Is a good free calling software easy to use, or should we proceed from its essence, such as whether the login method is cumbersome? They say it's a free phone call, so how can it be free? It's also a free call, which software is used more? In this session, we will focus on the comparison here.

Wechat phone book:

Wechat phone book adopts the login mode of WeChat binding, and you can log in by using WeChat account. From the overall interface, it is still relatively simple, and some are similar to the earlier dialing methods of Apple's iOS6 period. There are four functions below: "Dialing keyboard, call record, contact person and short message". But there is no obvious sign to enter the free dialing option.

When using the free call function, the WeChat phone book needs to remind you to bind the mobile phone number first. Its advantage is that there is no limit to the duration of the call, but its disadvantage is that both parties must install the WeChat phone book client at the same time to realize the free call, otherwise they can only make ordinary calls at normal charge.

Touchpal phone:

TouchPal mobile phone also uses the form of mobile phone number verification and registration, through which it can have the function of calling number display. New users can get more than 600 minutes of free talk time after registering (non-TouchPal mobile phone and landline talk time), and invite friends to register to get more free talk time. The following is also divided into three functions: contact, dialing and life yellow pages.

When dialing, you can directly choose whether to dial by toll-free phone or ordinary phone. There are no restrictions on the form of mobile phones and fixed telephones, and the other party can make calls without installing a TouchPal phone client and connecting to the network, so the use mode is much more flexible.

360 free calls:

360 toll-free phone can also be registered directly with the mobile phone number, but at present, the software is not fully open for registration, so it is necessary to grab the experience qualification or register with the invitation code. It is also composed of four options: dialing, contact, message and personal center.

You can use the toll-free phone function to make direct calls to domestic mobile phones and fixed telephones, and the other party can make calls without installing a 360 toll-free phone and connecting to the Internet. The first batch of 65,438+10,000 users can give 99,999 minutes of free talk time, and ordinary registered users can give 360 minutes of talk time. When calling a friend who has installed 360 free calling software, the clock will not be deducted, and users who have not installed the client will be deducted.

CreditEase Tel:

At present, Yixin telephone is in the form of open registration, which can be verified by SMS. After registration, you can get 260 minutes of free talk time, send 10 free text messages every day, and leave 15 phone messages every day, which mainly consists of five options: "message, phone, discovery, address book and me".

Dialing design directly adopts the form of free telephone, and ordinary telephone dialing cannot be used directly. When dialing, you can choose a more stable and clear dedicated telephone mode and adopt the callback mode to ensure clearer voice quality. We can make direct calls to domestic mobile phones and fixed phones within a limited number of free phone minutes per month, and we can call the same party without installing Easy Mail and connecting to the Internet.

Have a letter:

Youxin is currently in the form of open registration, and you can register and log in through SMS verification of your mobile phone number. However, you can get 50 minutes of free talk time after the first registration, and you can also get free talk time after logging in every day. It has four functions: dialing, address book, discovery and me.

When making a phone call, it will automatically match the number entered and determine whether there is a free phone call. Use the toll-free phone function to make direct calls to domestic mobile phones and fixed telephones. Similarly, you can call the other party without installing a toll-free phone client and connecting to the network.

The difference between these five softwares

TouchPal phone gives the longest free call time, which is 650 minutes, and only needs the calling party to support the installation of the client. Although Yixin Telephone and Xinyou also support the caller to install the client, the called party does not need to install the client, but the free talk time is discounted. Although the WeChat phone book is not limited in traffic, it requires both the calling party and the called party to install the client, and it also relies on the support of the network and does not support callback, so it does not have many advantages.

Note: Call-back mode, that is, the current call-back mode of VoIP is two-way outgoing mode. After the caller dials the other party's number, the system will dial back in reverse, and the call between the two parties can only be established after the caller answers. Therefore, callback is indeed twice as expensive as direct dialing, but it is still much more favorable than traditional calling. But the callback is a three-way call, and the waiting time for dialing is long. Both the calling party and the called party display "No number or unknown number".

At present, telephone marketing and telephone fraud are repeatedly prohibited, especially in the middle of the night, which may affect life. For business people or users who usually have more telephones, it is very necessary to identify strange numbers. Many free calling softwares do not have the number display function, which will make people mistakenly think that they are harassing calls and bring unnecessary trouble. For all kinds of harassing calls, how about the phone marking function and caller ID function of the five softwares?

Including WeChat phone book and TouchPal phone, are all services that support caller ID numbers, but some letters are recognized as other information at this point. If you need to display numbers accurately, you need to pay, which is not a good way for software that uses free VoIP.

Auxiliary functions:

Both TouchPal Telephone and 360 Toll Free Branch support blacklist management, whitelist management and harassment interception. It is worth mentioning here that TouchPal mobile phone also supports the auxiliary functions and features of Life Yellow Pages, including life convenience options such as charging phone bills, checking violations, checking express delivery, etc., all of which can be queried with one click, and the trouble of installing other auxiliary tools is also eliminated.

Call quality comparison:

In addition to the comparison of several commonly used projects, we should focus on their call quality. After all, in the past, due to the limitation of network speed, the experience of free network calling software was not good, and sometimes the call was delayed, echoed and unclear. And each family has different optimization in this respect. Now let's compare them and see how they perform.

Evaluation criteria: after many telephone calls, the average value is finally taken.

A: Close to the quality of mobile phone calls.

B: It's a little worse than the 2G network call of the mobile phone.

C: the call quality is average

D: The call quality is poor, and there are noises, jams or delays.

According to the comparative test results of several softwares for many times (the network environment is different, here is for reference only), the call quality of E-mail and TouchPal is the best, and the call quality of E-mail is almost the same as that of ordinary 2G network calls, but it takes a little more time, which is the characteristic of callback method; TouchPal originally communicated through the network link, but by adopting advanced coding and decoding technology, TouchPal also has a unique technical algorithm in echo, noise and delay processing. In the random noise matrix, filtering through the filter with complex algorithm, optimizing the handheld device at the same time, taking into account the performance of hardware devices, and eliminating the echo to the maximum extent, and finally restoring the clearest voice, which is also a very necessary factor for its good call quality.

Comparison of system RAM occupancy:

A good free call software should not only ensure the call quality, improve the auxiliary functions and have more free call time, but also optimize the Android system mobile phone, otherwise it will occupy too much system available space and slow down the overall running speed of the mobile phone.

According to the actual test results, the minimum occupied space of TouchPal's RAM is 16.3MB, while the maximum occupied space of the letter is 23MB, which is similar to the other three calling software.

Bian Xiao abstract

As can be seen from the above data, the most prominent and stable features of EasyTrust and TouchPal are that the former uses callback mode in terms of call quality and traffic consumption, TouchPal takes advantage of long free call time, and TouchPal adopts crowdsourcing compensation technology strategy. If a conversation consists of 20 voice packets, TouchPal uses a unique algorithm when the voice packets numbered 17 and 18 are lost. WeChat phone book mainly relies on WeChat, occupying the advantage of the number of users. In fact, its free call experience is not dominant in these five softwares, and even the caller and the called party need to install the client, which seriously affects the user experience.

Nowadays, more and more software application vendors are participating in the battle for free software calling. How to choose a suitable free calling software is a problem that we have to think about. I hope this article can be your reference.
