SIP & Cellular Providers Send Your Calls Unencrypted
Think your Skype calls are encrypted and unmonitored? Think again. Only a tiny fraction of VoIP providers offer SIP encryption (e.g. Skype) and this is rarely enabled on the SIP provider’s side, which means your voice conversation is sent as an RTP stream of data that is not encrypted or protected in any way. Even if your VoIP network provider claims that the calls are encrypted they still go through the provider’s servers, meaning that all your voice conversations can be easily intercepted and decrypted on the fly using a well-known attack called Man-in-The-Middle (MiTM). A MiTM attacker intercepts the communication and relays messages between the two end-points, making each believe they have a secure channel to the other.
Furthermore, keep in mind that your cell phone calls are also logged & recorded by default by your network operator as well no matter what the cellular network standard is (GSM, 3G, LTE, etc.).
Since call interception is done in what is known as 100% passive mode, there is really no way that you can know whether your calls are being recorded. There is simply no way that you can detect passive interception. It is also a well-known fact that governments of many countries obligate cellular network operators to store calls data for at least 6-12 months for security and analysis purposes. Moreover, many cellular standards are already cracked by hackers, allowing interception of live phone calls with a fraction of money invested into hardware.

Protect Your Voice Calls with Military Grade End-to-End VoIP Encryption
We strongly believe in verifiability and openness when it comes to providing the best privacy for voice communication. In any real-time voice encryption product, security can only be strong when the following procedures are met:
- Unbreakable encryption algorithms (Advanced Encryption Standard AES256 or Blowfish256).
- Strong end-to-end encryption. Mobile devices must be connected directly using unbreakable, open-source ZRTP protocol. Voice traffic must not go through a SIP provider’s servers to avoid a Man-in-The-Middle attack.
- The secret keys used to unlock the encryption must be destroyed by the client’s software immediately after finishing a call session.
- The client’s software must be open-source to ensure there are no backdoors built-in by a software developer which can be used to intercept voice traffic or bypass encryption.
- Man-in-The-Middle attack protection. To provide reassurance to end-users that they have a truly secure connection. MitM is a classic method of eavesdropping on encrypted communications.
- Simplicity and compatibility. No special knowledge should be required to use voice encryption. The client’s software must be compatible with popular smartphones such as Android, BlackBerry, iPhone and Nokia.
- No logging or recording of calls by the VoIP network provider.
Our Secure VoIP Solution meets all of the above requirements. It uses encryption algorithms that are recommended for military and government secure communications and its secret keys never leave the mobile device. Furthermore, all of our secure VoIP servers are used for call negotiation procedures only (in other words to allow you to locate & establish a secure connection with the recipient’s phone). Therefore, we are the only company who can offer you truly a secure peer to peer VoIP solution since all your voice traffic is always encrypted and does not go through our servers. The encrypted connection is established between the two clients only, making impossible to exploit a MiTM attack. With the computer technology presently available to humankind, it is currently impossible for someone to decrypt VoIP ZRTP voice traffic in real-time and listen in on your conversations.
