VoIP and IP telephony. What's the difference?
One of my readers sent me an e-mail today asking to know what is the difference between VoIP and IP telephony. After replying his e-mail i decided to make a post here about this topic. These two terms are use frequently interchangeably but they are in fact different. VoIP describes the actual method of transmitting voice over an IP network while IP telephony describes telephony devices that use IP as the native transport for voice and call signalling. IP telephony needs VoIP to send calls over the network but VoIP does not nee IP telephony. This blog is about these two amazing technologies that is changing the way we communicate

Solomon - It should also be noted that most of today's TDM traffic is transported over IP. Although the carriers will tell you that VoIP is not capable of doing all of the things that the legacy networks do ALL major carriers use VoIP for primary transport (long distance and international).
There are a few obstacles to overcome before full transparency can be achieved. The primary one is how is government able to tax your phone calls. For 50 years this has been easy money and VoIP makes the entire question much more difficult from a taxation and accounting point of view.
I would suggest that all fight any legislation that may come up no matter how insignificant it may appear to be!
