Advantages
Security is not the only reason to pass Voice over IP through a virtual private network, however. Session Initiation Protocol, a commonly used VoIP protocol is notoriously difficult to pass through a firewall because it uses random port numbers to establish connections. A VPN is also a workaround to avoid a firewall issue when configuring remote VoIP clients. However latest VoIP standard STUN, ICE and TURN eliminate natively some NAT problems of VoIP.

Famous quotes containing the word advantages:
“A woman might claim to retain some of the child’s faculties, although very limited and defused, simply because she has not been encouraged to learn methods of thought and develop a disciplined mind. As long as education remains largely induction ignorance will retain these advantages over learning and it is time that women impudently put them to work.”
—Germaine Greer (b. 1939)
“If we help an educated man’s daughter to go to Cambridge are we not forcing her to think not about education but about war?—not how she can learn, but how she can fight in order that she might win the same advantages as her brothers?”
—Virginia Woolf (1882–1941)
“Men hear gladly of the power of blood or race. Every body likes to know that his advantages cannot be attributed to air, soil, sea, or to local wealth, as mines and quarries, nor to laws and traditions, nor to fortune, but to superior brain, as it makes the praise more personal to him.”
—Ralph Waldo Emerson (1803–1882)
