If you are interested in learning a few basics about a VoIP
system, this article should be very helpful in assessing you with the basics.
Most people are familiar w/ NetMeeting and other software that let you talk
to others over the internet. VOIP is similar. However, it also uses your
phone. Instead of connecting your phone to the wall, either you connect
it to a box the VOIP Company provides or you buy on your own. This is the
modem. You need high-speed/broadband internet for this. Your modem plugs
into your cable/DSL modem and now it can 'talk' between your phone
and the internet.
Your phone lines already do pretty much what VOIP does, just w/ different/older
technology. It is easy to set up. Assuming you have the company send
you a modem or you buy a kit at the store, you simply plug the modem between
your current cable/DSL modem and your computer.
It also has a phone jack for your regular phone.
Some wonderful VOIP features include caller id, call waiting, call waiting
caller id, and call forwarding. Voicemail and email alerts for new voicemail
are other features. Web access to voicemail (which means you can play
your messages on your computer is another advantage), as well as auto-forward,
if the phone is ever down or is not answered, it is auto-routed to another
number. Computer dialing allows you to highlight any number on your
computer, hit F6 and it sets up the call from your phone to another.
There are some other helpful features available for extra money,
such as the soft phone, which lets you use your computer as a phone w/o
the modem. This means you can take your laptop with you wherever and
you have your phone with the same phone number everywhere too.
