One of the ways to secure the phone calls through encryption is through the use of VoIP technology. This technology consists of two or more (for conference calls) IP phones and IP network that can be connected to traditional phone system. The technologies goal is to not allow person or people to intercept (tap) the phone call at its various points.
The Reason for the chosen topic:
In a last couple of years there was rise in interest towards safety of data transmitted through phone calls, especially in respect with latest information regarding NSA collecting data about peoples phone calls. So we chose this topic because we thought it would be interesting to see if phone call encryption technology really works and if it provides significant benefits to the businesses who use it.
