VoIP phones with Ethernet connections
A VoIP phone with an Ethernet connection is the easiest type of VoIP telephone to use. Instead of a standard telephone RJ-11 connector to plug into the PSTN, these phones have RJ-45 connectors to plug into Ethernet networks.
The Ethernet connection is used to connect these VoIP phones to the VoIP server or VoIP gateway.

What is VoIP Security?
Any technology that involves transfer of data or information is prone to compromised security. It happens with telephones, cell phones, email and Internet transactions. Because VoIP (Voice Over Internet Protocol) has the internet as its mode of transference it’s possible to have your Internet-based called intercepted. To make matters worse, there are techno-troublemakers who are armed with the hacking skills needed to eavesdrop on virtually any call over the Internet they want to. It is impossible to ensure total security on information flow over the web including Internet based phone calls. As new technologies emerge with more highly developed security protocols, there will be those who consider it a unique challenge to crack these online defenses rendering security advances antiquated. The Internet has been notorious for alternating security breaches and accompanying fixes.

As VoIP becomes more popular, VoIP security continues to be stressed as a key to advancement of this technology, especially since it will thrive in the realm of the World Wide Web. There are, however, advances in VoIP security that have been utilized by VoIP providers in order to ensure protection of customer’s personal information.

VoIP Security is IP Security
VoIP is vulnerable to all security issues that generally affect the traditional IP data networks. This includes viruses, worms and denial of service (DoS), spoofing, port scanning, unauthorized access from a third party. and toll fraud. In short, the same issues you deal with in compromised Internet function can be linked to the use of VoIP technology.
