Many businesses are switching from a traditional phone system to a Voice over Internet Protocol (VoIP) system to save money. However, while a VoIP system costs less to install and maintain than a landline system, it isn't as secure. So, if you plan to use a VoIP phone system for your business, you need to learn how to keep hackers from obtaining confidential information, sending viruses into your system, and racking up costly phone bills.

Beef Up Your Password

In order for hackers to gain access to your VoIP system, they need to get past your password. So basically, your password is your first line of defense and it needs to be elaborate. Don't choose a password that's simple. Instead, choose a password composed of uppercase and lowercase letters, numbers, and symbols. Also, don't use a password generator to create your password. Many password generators recycle different passwords instead of creating a new password each time they're used. So, if a hacker has made note of the passwords the program generates, it won't be hard for him or her to hack into your VoIP system.

Control Access by Whitelisting IP Addresses

When you set up your VoIP phone system, set it so that you have to whitelist each individual IP address before the system can be used. Once the system is set so that only approved IP addresses have system access, it automatically blocks IP addresses that aren't approved. In order to give someone access to your VoIP system, you simply type their IP address into the system.

Block International Calls

In order to keep hackers from running up your phone bill, block all international calls, with the exception of any countries that you need to call on a regular basis. The process is reversible. So, if you need to unblock specific countries at any time, all you have to do is call your service provider.

Update and Test Your Software

You should always keep your VoIP software up to date so that you can enable the latest security features. Also, occasionally have a professional security tester test your VoIP system's security features to help you identify any security weaknesses.

Don't let the threat of someone hacking into your phone system keep you from switching to a VoIP system. Instead, take some time to make sure you have a strong security system in place. By creating a good security system and having a professional test your system's security features, you shouldn't have to worry about security problems.
