How to make anonymous calls to anyone?

Isn’t it insanely amazing how technology has advanced, how time has revolutionised and how at single click thousands of miles of distance succumb to exist! Voice timing and face timing have really made this world a small place. But whilst the National Security Agency (NSA), a national-level intelligence agency of the United States Department of Defence, constantly tapping our phones it seems really a herculean task to get anonymity on the internet. Everything we do is recorded and stored in the huge ocean of internet data. Here I will let you know few legal ways to clear the phone call footprint!
‘A man has no face’, here I quote one of the quirkiest line of the most sought-after TV series of our times, Game of Thrones. To achieve this anonymity these are the few things you can do-

1. Buy a prepaid phone.
The easiest way to do this would be a buying a prepaid phone, which can be easily fetched from any nearby store. Make sure you buy it with cash. Do not store any contacts on it and do not call anyone via it because that might leave a trace. Keep the phone in a switched off state with the battery out until you need to make the call. There you have it!
2. Disguise your Caller ID with SpoofCard.
One of the most popular techniques is using spoof call to disguise your caller identification code. You can get the free trial of this website which is also available in application format. You will then have to connect with them. Once you get connected with SpoofCard, you can choose which number must be displayed on the person’s screen, whom you want to call anonymously. SpoofCard also provides a voice changer where in you get to spoof your voice to an opposite gender. SpoofCard is legal with a lot of government agencies using it.
3. Use Google voice as a proxy number.
Google voice allows to have a free and legal phone number without you having to compromise your identity. This number can be connected to your phone, email or can be used on the desktop as well. In this way, this number acts as your proxy number. Well suing Google voice you can receive calls and messages for free, but for calling using this proxy number you need to buy some talk minutes. This can be used where you don’t want to compromise your identity but at the same time need to contact with the person. Though the person you are calling will not know your real identity, all the texts, calls and numbers will be logged in Google since it owns this service.
4. Use *67 before dialling a number.
This feature allows to block the caller identification. If you dial the *67 before the phone number of the person you want to call anonymously, it will appear as ‘unknown caller’ or ‘blocked caller id’. This ensures that the person cannot call you back or get your name. This can be also used in land lines. This is a cool technique but the issue is that the phone company can easily access your hidden identification. NSA can also tap into such calls.
5. Using payphones.
Payphones are one of the easiest and ancient way to make anonymous phone calls. They can be found without much hassle, around street corner. They accept coins and give a cent percent guaranteed anonymous calls, anyway you will have to be careful about security cameras for the sake of being safe from being recorded. Try paying the payphone using coins or cash. Do not use cards or any sort of digital payment technique because that might leave trace which can bring your anonymity to stake.
7. Outbound caller id blocking.
