Using VOIP for business communication has become more popular recently due to the benefits and features that it offers. Not only that, but the price is very attractive. Unfortunately, there have been more security concerns recently since VoIP goes over the Internet. This means that things like viruses and hacking can happen to it, just like anything else that’s online.
For instance, the majority of VoIP goes over the internet without being encrypted. This means that anyone who has the right software and network access might eavesdrop on the calls. This can give them access to personal, company or proprietary confidential information.
So, how do you make it more secure? Well, we have included some tips below to help keep your VoIP secure.

With remote employees using your VoIP system it’s extra important to make things secure. Using a VPN to secure the calls is a great way to ensure everything stays secure.
