VoIP
Data flow is orderly and in line.
Telephone Fixed (dedicated) Lines
Pricing Scheme (per call)
VoIP uses packet switching, which breaks the
conversation down into packets of data and mixes
in with other packets of data, such as e-mail
messages and Web pages. Numerous routes from
sender to receiver.
