VoIP is the abbreviation for Voice over Internet Protocol, also called IP Telephony, Internet telephony, Broadband telephony, Broadband Phone and Voice over Broadband. It is the routing of voice conversations over the Internet or through any other IP-based network.
Cost
In general, phone service via VoIP is free or costs less than the equivalent service from traditional sources. VoIP to VoIP phone calls on any provider are typically free, whilst VoIP to traditional phones generally costs the VoIP user.
Functionality
VoIP can facilitate tasks that may be more difficult to
achieve using traditional phone networks:
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
wherever you connect to the Internet, you can receive
incoming calls.
VoIP systems include features that many
telcos charge extra for, or may be unavailable
from your local telco, such as 3-way calling, call
forwarding, automatic redial, and caller ID.
Mobility
VoIP allows users to travel anywhere in the world and still make and receive phone calls.
