Voice over Internet Protocol (VoIP) networks has unchained users from the autocracy of telecom giants, allowing people to make telephone calls over the Internet at affordable prices. However VoIP may be simple and economical, it’s notoriously deficient in security. With nominal effort, hackers can snoop on conversations, interrupt phone calls, modify caller IDs, introduce unnecessary audio into existing phone calls and gain access to secured information.

The data vulnerability gets affected because IP phones don’t comprise the public phone network, where hacking requires a precise, physical link in terms of a wire.

Using of multi-level protection embedded with security for instance WPA, IEEE offer built in encryption and authentication technology. Using a VoIP firewall that would prevent unwanted traffic trying to gain access to VoIP through wireless devices is also recommended. Lastly, making people aware of the importance of VoIP encryption is very important and every organization should conduct training for their employees to educate them.
