Using a VoIP provider gives you more of a measure of security than relying on freeware systems available on the Internet. The primary defence mechanism of any computer is the firewall. Providing a barrier between your computer or network and security threats such as hackers and viruses, a firewall offers a degree of protection that filters data going in and out of your network. As VoIP works by breaking voice messages into digital data, a standard firewall installed in your PC may not be enough to offer you full protection. VoIP providers have much more stringent firewalls installed on their main servers, which protects the entire network and all machines linked into that network. This is one of the primary reasons why, if you’re serious about using VoIP on a regular basis, it’s best to sign up with a bona fide VoIP provider such as Vonage.
