The availability of the internet in all corners of our nation has made it possible for whole offices to unshackle themselves from heavy telephone sets as well as unsightly wires and unnecessary call centers in favor of a more portable, convenient, reliable an affordable service which uses the internet to transport voice and data in small-size data packets. That being said, there are a lot of security vulnerabilities that one may face if they haven’t done their research before settling on a trusted VoIP provider.

VoIP is not immune to these events, and it’s not impossible for hackers or business rivals to try to bring your VoIP network down in order to acquire valuable data or slow down your success.
