As VoIP becomes more mainstream in homes, businesses and school campuses, the subject of VoIP firewalls has never been more important. Firewalls are internal devices or software that monitors communication between trusted and untrusted sources. VoIP users are now seeking the security of firewalls that are specifically designed for IP voice communications.

How it Works

Essentially, a firewall is a security barrier between you and a source that may wish to do you harm. A regular firewall on your computer may not cover all security issues that stem from VoIP use, however. In fact, it could even disrupt your audio signals.

Standard firewalls can not distinguish voice packets from data packets and, while both packets try to make it through, voice quality could diminish or be stopped altogether. This is an issue that the VoIP industry is trying to address and now there are firewalls specifically configured for voice communications.

What to Look For

There are two ways to avoid issues with VoIP communication and firewalls. One is to update your existing firewall with the help of an IT professional. Some newer firewalls can be easily configured to protect VoIP users from both hackers and audio disruption.

Businesses that have implemented a large VoIP system may need to install a VoIP-specific firewall rather than updating an existing, possibly outdated firewall. There are several VoIP companies now offering firewalls for easy installation, to which you should direct your IT department.
