Encrypted Calls from Your Smartphone

What is encryption in communications about?

You may have seen on more than one occasion that some applications use end-to-end encryption to provide greater protection and confidentiality in calls and chats.

Everything you need to know about encrypted calls

As we mentioned, what these types of applications do is hide the information that is transmitted and this is achieved thanks to codes that protect the data.

Secure Call for more telephone privacy settings

This native service has a triple security level made up of: TLS (Transport Layer Security), ZRTP (Zimmermann real-time transport protocol) and ICE technology for P2P. Calm down! We are going to explain each one to you.

What are your three levels of security?

Why is this service so complete? As we mentioned, it includes three levels of security, we are going to explain each one to clarify all the doubts that may arise:


Transport Layer Security, which translates security into the transport layer, is the first level offered in this encrypted call service. It is a cryptographic protocol that provides a privacy setting in communications that travel over the Internet.

  • Handshake or by mutual agreement: encrypts and packages the information assigning an authentication code that can only be deciphered by the parties involved.


Zimmermann real-time transport protocol, the man-in-the-middle protocol, provides greater security to communication points, how? Since there are multiple ways in which criminals can access your information, the function of this tool is to prevent it to the max.

ICE technology for P2P

The ICE, which translates to Establishment of Internet Connectivity, is a fundamental technology in P2P systems for them to function properly. Let’s go in parts:

Secure Call, the best option in encrypted calls

Now that you fully know their security levels, we know that you are going to want to join this communications revolution. Do you wonder how the app works on the phone?

Bitwings aims to offer smartphones with futuristic technology to all its customers at competitive telephone rates and transmission of encrypted data.
