Voice data is converted to internet protocol data and sent over the
internet the same way that information is sent for the web pages you browse. It may be
converted at your location or it may be converted by the location you call to place your
call. To convert from your location, there are two possible ways. You could use your voice
card and speaker to be your phone. Then the program in your computer would convert the
voice to IP data and it would be sent to the destination you specified. You also could
plug you telephone into a card in your computer or a box attached to your computer. The
electronics would convert the voice to IP data. To convert outside of your location, you
would call into a local number much like using a calling card. If you are calling from a
phone number the system recognizes, you would be given another dial tone. Otherwise you
would be prompted for a login number and password (this enables you to make a call when
you are away from home). You would then dial a long distance number the way you normally
dial. The electronics would convert the voice call to IP and route it to another piece of
electronics local to the number called. That local electronics would generate a local
phone call and convert the IP back to voice. |
