| VoIP (Voice over
Internet Protocol) is simply the transmission of voice
traffic over IP-based networks.The Internet Protocol
(IP) was originally designed for data networking. The
success of IP in becoming a world standard for data
networking has led to its adaption to voice networking.
The Economics of
VoIP
VoIP has become popular
largely because of the cost advantages to consumers over
traditional telepone networks. VoIP calls can be placed
across the Internet. Most Internet connections are
charged using a flat monthly fee structure. Using the
Internet connection for both data traffic and voice
calls can allow consumers to get rid of one monthly
payment. In addition, VoIP plans do not charge a
per-minute fee for long distance.
VoIP Telephones
There are three methods
of connecting to a VoIP network:
- Using a VoIP
telephone
- Using a "normal"
telephone with a VoIP adapter
- Using a computer
with speakers and a microphone
Types of VoIP Calls
VoIP telephone calls
can be placed either to other VoIP devices, or to normal
telephones on the PSTN (Public Switched Telephone
Network). Calls from a VoIP device to a PSTN device are
commonly called "PC-to-Phone" calls, even though the
VoIP device may not be a PC. Calls from a VoIP device to
another VoIP device are commonly called "PC-to-PC"
calls, even though neither device may be a PC. (Source:www.tech-faq.com) |
