its a business like any other....you have so many companies out there, all just trying to get you to sign up and collect your money...then you have all those jerks here on yahoo answer selling there dumb calling cards, which is spam and against the yahoo rules.
Reply:The process is IP-telephony. It is possible to exchange digital information with the Internet. The most known example is an e-mail. However, it is technically possible to digitize and send a sound as well. And in this sense IP-telephony systems use the Internet for sending fax or voice between two users of computer in real time.
