What should you do when you want to record a cell phone call?

　Since my seniors gave it to me when I was a student, I bought Pioneer's latest cordless answering machine because the Kenwood answering machine, which had been used for nearly 17-18 years, broke down.

　Probably not leaked, the number of landline calls at home is astonishingly small. However, because a lot of phone numbers have been written in what contracts and member registration occasions, it is true that the relevant procedures can not be abolished up to now. Therefore, 80% of the incoming calls are harassing calls. It cannot be said that the sales of junk calls from communications companies account for 10%. They are considered to be the guidance of credit institutions to confirm that such late-night single-cut calls account for 10%. The setting of the new telephone does not have much tension.

　However, I wonder if it is because the fixed-line phone has not been replaced at the 20-year level, and I am a little surprised that the "recording" button is installed in the place where the latest handset is fairly easy to press. It can also be set to start recording automatically when an incoming call is answered, and it also has the function of starting a call after the meaning of the recording is directed to the other party. Although the model purchased is not the superior model, it also enriches the call rejection functions such as non-notification and rejection of calls from free phones.

　Looking at the recording methods of the manual, we can also feel that the main user layer of fixed telephone is centered on the elderly, and the response to junk phone becomes more important. Even the recording function of the call is expected to give up the bad effect of persuasion.

　On the other hand, what about mobile phones, especially the latest feature block, smartphones? Call recording, etc., seems easy to implement on APP, but the reality is that the advanced operating system that must often deal with hacking and hijacking is the enemy, or the recording of calls on APP is restricted accordingly (call recording is illegal in some countries). For example, in iOS applications, for calls, you cannot record each other's voice or your own voice in an orthodox manner (some recording devices are connected to external terminals).

　On Google Play, although there are corresponding applications that can record each other's voice and their own voice (that is, the content of calls), most of them are matched with the functions of uploading to cloud services such as Dropbox, and many voice calls are unstable, so the author and others feel uneasy about using them. Some of these specifications can only be thought of as spying tools, such as extolling full automation by not displaying application icons. Maybe it's because the call recorder app itself is adjacent to abuse on smartphones, which makes people feel a little suspicious. In a fixed-line telephone, it is also felt to be an irritating part because it is a function that can be used with a button.

　Simple contact, through SNS and email can, as a result, dare to communicate through voice calls, even individuals, its importance will increase a lot of cases. Situations related to some kind of dispute, such as having to talk to the other party directly, often think that "you want to keep it as evidence" before making a phone call. Even if there is no failure, there are cases in which you want to confirm the communication when you call the support center later.
