protocol which is used to send sound and data signals over
the internet at very higher transfer rate, making the
overall online communication faster and easier.
Some broadband connections may have less than desirable
quality. Where IP packets are lost or delayed at any point
in the network between VoIP users, there will be a momentary
drop-out of voice. This is more noticeable in highly
congested networks and/or where there is long distances
and/or inter working between end points. Technology has
improved the reliability and voice quality over time and

While the traditional Plain Old Telephone System (POTS) and
mobile phone networks share a common global standard which
allocates and identifies any specific telephone line, there
is no widely adopted similar standard for VoIP networks.
Some allocate an E.164 number which can be used for VoIP as
well as incoming/external calls. However, there are often
