Voice over Internet Protocol is a medium of communication for most businesses and large companies. They usually partner with their clients and other organization sharing sensitive data and information over VoIP as their internal communication and other processes. One of the most significant risks that these businesses watch out for is the interception of data hackers and other parties that are also on the job of causing damage. This is mostly encountered on a daily basis when a company’s VoIP system is not well taken care of and when their system would face problems.
However, there are many ways to solve such problems in the market by encrypting VoIP calls. In that way, these calls will be better regulated and monitored, minimizing these risks for both businesses and clients. Encryption of Voice over Internet Protocol calls is essential and vital to their users. This feature is to better secure data and information and is seldom considered by people.
There are two ways of industry protocols that are designed for securing VoIP calls and choosing these standards is the best way to improve calls including data and privacy information.
The first cryptographic protocol is the TLS Protocol. It encrypts and secures SIP messages that are sent by a PBX or a software. The advantages of having TLS Protocol in your VoIP system is that when it is enabled, SIP messages cannot be read, altered, or intercepted by hackers and intruding parties. TLS is also recognized as a security standard as it allows unlocking of VoIP around the world in many mobile networks that are being blocked.
Moreover, another capability that TLS has is the power to bypass Network Address Translation issues on 3G/LTE networks.
The other cryptographic protocol for VoIP systems is the SRTP Protocol. Cisco and Ericsson develop it in the year 2004 which can encrypt RTP media or audio streams. It can protect and secure ongoing calls, making sure that no other party can do an alteration, interception or reading to the request. The SRTP Protocol is also a recognized standard and is already being utilized and supported by most VoIP devices.
These protocols are significant and helpful in preventing existing problems in companies and businesses that use Voice over Internet Protocol systems. Each organization that is VoIP equipped should typically have the freedom to choose their company’s level of security for communication and should also have the right to know that these protocols do exist.
