While many companies are turning to Voice over Internet Protocol phone systems for their ability to add features coupled with their cost savings, the fact is: Internet telephony is vulnerable.
These types of phones aren’t part of a public phone network, meaning there’s no safety net for tapping or listening in on phone calls.
Instead, phone calls made over the Internet or via a LAN or WAN can be intercepted by just about anyone. What does this mean? Virtually anyone with the right know-how to listen in on your business and personal phone calls.
To protect against snooping, you’ll want to encrypt your phone system. VoIP voice traffic is transmitted over various networks and therefore can be protected by encryption. VoIP encryption tools are readily available and can make it nearly impossible for others to listen in on your calls.
Here’s a look at a few VoIP encryption tools:
Some Systems Come Encrypted
Companies have heard your complaints when it comes to keeping VoIP phone systems secure. Now, many companies that sell or make VoIP systems have started incorporating encryption into their software.
An example comes from Skype, which has encryption support already installed into its software. Before you buy a VoIP system, check to see if encryption services are available or already installed in the software.
SRTP Protects Highly Confidential Conversations
Secure Real-Time Transfer Protocol (SRTP) has almost no effect on call quality, and a unique encryption key is created for each call you make, thereby making eavesdropping extremely difficult. This is particularly effective for businesses that have highly confidential conversations over the phone.
TLS, IPsec a Popular Choice
Transport Layer Security (TLS) and IP Security (IPsec) are both gaining traction. TLS will encrypt VoIP data between two applications. IPsec will encrypt information for two devices as well as the applications running on them. The goal is to keep unauthorized people from listening or interfering with your phone calls.
VPN Works But Needs More Protection
You can use a Virtual Private Network’s (VPN) built-in encryption feature to protect your VoIP calls. The feature can be used for all calls, whether it’s an employee in a remote location or someone logging in to the VPN from a laptop. However, you’ll need more protection once calls are on your LAN.
Zfone Easy to Install But Comes With Challenges
The chief designer of Zfone also created the world’s most-used email encryption software. Installation is relatively easy and can be used by anyone. The latest beta version can be downloaded for free.
However, Zfone is a two-way street. In order for it to work, it has to be installed on both ends (your business and the people/business that’s calling you). Therefore, your calls to a particular client will be protected, but your call to the bank might not be protected.
VoIP technology has brought companies many benefits. However, with as many features and advantages as VoIP has, there are vulnerabilities. Make sure your business isn’t at risk with these encryption tips.
