Top 5 VoIP security tips for businesses

VoIP security is something every business should be on top of. Here’s 5 tips to get you started.


VoIP, short for Voice over Internet Protocol, allows businesses to make free, or very low-cost, telephone calls over the Internet. This works anywhere in the world, regardless of the equipment that the other person is using.

While VoIP is a valuable tool for businesses, it is not without its problems. If the right security measures are not put in place, you could be subject to identity fraud and several other cybersecurity threats. Here’s what you need to know about securing your business.

Enabling Data Encryption

Data encryption refers to the act of changing electronic information into an unreadable state via the use of complicated algorithms and ciphers. Encryption should be an essential part of your overall cyber security strategy. Since VoIP data can travel over numerous networks, making it more susceptible to the possibility of being intercepted, it is particularly important here. The most popular tool for encrypting VoIP calls is Zfone, a free program that works on Windows, Mac, and Linux machines.

Implementing Authentication Techniques

Service abuse and toll fraud are among the most common cases of VoIP attacks. This allows individuals to make premium rate service calls to their own services, often located outside the country, and then charge the cost back on to your business. Implementing mutual authentication protocols between parties is one of the best ways to prevent this. This could be done through a password, pin, or other classified information.
