Voice over IP ( VOIP)

Digitization of voice phone calls has been around for some time and is a mature science

at the Ma Bell level. It is a rather new addition at the residential and small business level.

Satellite systems do not lend themselves well to VOIP due to the terrestrial delay

indicative of the time it takes for a packet to make a round trip from host to satellite to

NOC to internet and back. Some services do not function at all as they falsely assume

that since it took so long for the packet to traverse the network that the link must be

down. Those that do function produce calls and conversations reminiscent of turn of the

century transmissions form Eurpoe with built in 3 second delays between query and

response.

Vonage, Skype, and Packet8 are some service providers.
