VOIP Software

VoIP (Voice over IP) This is the practice of using an Internet connection to pass voice data using IP and VoIP Software instead of using the standard public switched telephone network. This can avoid long distance telephone charges, as the only connection is through the Internet. Voice delivered using the Internet Protocol is a term used in IP telephony for a set of facilities for managing the delivery of voice information using the Internet Protocol (IP). In general, this means sending voice information in digital form in discrete packets rather than in the traditional circuit-committed protocols of the public switched telephone network (PSTN). A major advantage of VOIP and Internet telephony is that it avoids the tolls charged by ordinary telephone service.

The three most common ways to place a call using VoIP are -

ATA - The most common way to place a telephone way using Internet Telephony is ATA. ATA stands for analog telephone adapter; and it takes the analog signals from your phone and converts it to digital data ready for transmission over the Internet. ATA allows you to connect a standard telephone device to your computer for use with Internet Telephony. You need special VoIP software to make it work, but overall is very easy to use.

IP Phones - IP phones look and function just like your ordinary everyday phones but instead of routing your phones through the PSTN lines they route your calls through the Internet Protocol.

Computer to computer - This is by far the simplest way to use Internet Telephony. All you need are VoIP software programs that can route your calls. There are many VoIP programs available that you can use to many calls directly using your Computer. Other than the VoIP software you need a microphone, speakers, sound card and a fast Internet connection.
