iPhone holders face the problem of spying sometimes even more often than the users of gadgets running on other software. It’s vital to install a worthy VPN on iPhone if you want to be secure while talking to your better half or discussing the plans of the company you work on with your boss.

What technologies are used by iPhone holders?

The first prototype of a currently known portable gadget called a mobile phone appeared in the year of 1973. Motorola DynaTAC created a satellite phone that could function without a wire. It was the beginning of a new era when the companies around the world started thinking about the phones, which would function everywhere.

The first iPhone appeared only in 2007 but became extremely popular among users. People were ready to spend thousands of dollars on this new-fangled gadget.

iPhones were the first portable devices that could function with the help of the Internet. Thus, it became possible to exchange messages by means of VoIP.

What is VoIP?

Voice over IP or VoIP in short is a phone service that provides double-sided communication. Many people are confused by the notions of Voice over IP and IP telephony.

Voice over Internet Protocol is a common name for protocols, technologies and methods, which provide the delivery of verbal signals via the Internet or any other IP networks. The signal is transferred in a digital format.

Voice and video communication became wide-spread in the world by means of computer networks at the beginning of the XXI century. Today it is used both by individuals and corporate sector. The use of such systems allows decrease the prices of calls and integrate telephony with the Internet services.

IP telephony and Voice over IP are identical

These two notions are used while describing the telephone communication by means of IP protocol. This technology provides us with traditional dialing, two-sided voice-message report.

Nevertheless, VoIP is a wider term, while IP telephony is its application. VoIP technology presupposes all variants of voice transferring over IP including those which are not related to human communication. For example, Voice over IP technology is used to transfer sound in video surveillance systems, warning systems, webinar transmissions, online movies broadcasting and what not.

VoIP functions

Voice over IP handles tasks, which will be more difficult to fulfill using the public switched telephone networks. Thus, VoIP’s facilities are the following:

  •  The possibility to make more than one call at a time. Any extra telephone lines are not required.
  •  Conferences, call forwarding, recalls, calling-line identification facility are free if one uses VoIP technology.
  •  Safe calls by means of a standard protocol – SRTP.
  •  Independence from user’s location. Only the Internet is required to get access to VoIP.
  •  The integration with other internet services is allowed.
  •  Additional telephonic properties are easier and cheaper to introduce. Among them one may find call routing, pop-up windows, alternative GSM-roaming and IVR.
  •  Capacity to use one phone number in every corner of the world.

Speech encoding

When a person uses VoIP technology for communication, his/her voice is digitalized by means of pulse-code modulation, encoded and divided into small packages. Analogous process is accomplished in the opposite direction of a receiving party.

Some non-technical users are erroneous to assume that this encoding makes their communication secure. But it is not true.

Is it safe to use VoIP technology?

Until the person is online, his/her activity is not secure. In other words, if a hacker knows about the weak points of VoIP system, it can be hacked. And all user’s data may undergo leak.

Troubles with communication are possible

Similar to any network application, VoIP service may be subjected to any ‘classic’ attacks. But there is some specificity. For instance, a Call tempering attack is possible. It happens when someone ‘interferes’ the conversation sending empty packages of data. The system processes these data and as a result, the conversation will be slowed down or even impossible.

Besides, VoIP hacking is the most convenient way for monetization.

How does it work?

A fraudster finds a mistake in the service. After it he may call chargeable services, ‘sell the line’ and distribute audio-spam.

Another specific problem is the possibility of voice phishing and SPIT. Thus, a user is proposed to call a ‘service’ (like PayPal) to specify some issues. As a result, he/she pays more for the call or exposes the personal data.

Phishing and SPIT become more and more frequent as such attacks require only a special file, an automatic calling program and the users whose access to the Internet is not protected.

These threats made VoIP technology less popular among iPhone users.

New ways to exchange information

The world develops with rapid strides. And in this regard, more and more ways to exchange data appear. It’s more convenient to use Telegram or WhatsApp application than to send a wire, for example.

What is WhatsApp?

“What’s up?” – asks an American meeting his friend. This phrase became an idea to create a program for users to exchange messages via the net and inquire about family and friends.

What’s application or WhatsApp is a popular free system of instant messaging for mobile and other platforms. This application supports voice and video messages apart from ordinary text ones.

Just imagine, that user A sends 70% of his messages to user B. Then, user B disappears for some time and someone using unknown phone number sends an empty message. Who is this mister X? There is no doubt that it is user B.

  • In the second place, the authorities and special services like FBI or NSA are authorized to access any data. There are the cases when such services made the organization provide them with all necessary information. These organizations couldn’t refuse.
