  What is VoIP (Voice over Internet Protocol)
VoIP is the routing of voice conversations over Internet or through any other IP-based network.  The voice data flows over a general-purpose packet-switched network, instead of dedicated legacy circuit-switched telephony transmission lines.

VoIP can facilitate tasks that are more difficult to achieve using traditional phone networks. For example, incoming phone calls can be automatically routed to your VoIP phone, regardless of where you are connected to the network.  Take your VoIP phone with you on a trip, and anywhere you can connect to the Internet, you can receive incoming calls.

Protocols
There is a lot of debate over the two most popular types of VoIP; SIP and H.323.   Initially H.323 was the most popular protocol, though its popularity has decreased in the "local loop" due to its poor traversal of NAT and firewalls.   For this reason as domestic VoIP services have been developed, SIP has been far more widely adopted.
