In the case of POTS (plain old telephone service), voice calls are broken down into analog signals and passed from one location to another. So, voice calls in POTS can easily be traced and recorded as the analog signals can be easily caught with radar signal devices. Therefore, it is practically impossible to encrypt the voice calls in POTS. On contrary, VoIP breaks down the voice calls into data packets which are then transferred over the internet from one location to another. As a result, data packets might be exposed to external threats and confidential data might be compromised. In order to mitigate such risks and restore customers’ privacy, VoIP encryption is very much essential for any VoIP business.
VoIP users might be enticed to cheap long distance calling, but they are not ready to compromise their personal data during the process. Very often, hackers use this loophole to retrieve the confidential data from individuals and corporate consumers for illegal monetary gains. Such terrorizing of VoIP users can be efficiently negotiated with the help of VoIP encryption software which uses strong encryption layers to avoid detection by unauthorized users. So, every service provider should consider implementing VoIP encryption in order to offer secure calling experience to users.
How to implement VoIP Encryption?
The following are two famous methods of implementing VoIP Encryption:
1. Using Virtual Private Network – With VPN all the internet traffic can be encrypted via encrypted OpenVPN tunnel which includes the VoIP calls. However, routing VoIP calls through a VPN will slightly increase the bandwidth and produces some CPU overhead. On the brighter side, VoIP calls through VPN can avoid detection by ISP or corporate firewalls to avoid blockage.
2. Using VoIP Encryption Software – Certain established solution vendors offer VoIP encryption software which runs simultaneously with in-house softswitch. Basically, it is used to cipher the VoIP data packets going in and out of the softswitch and add encryption layer to it. Thus, it enables service providers to offer a compelling VoIP calling experience to users.
