How VoIP Service
Works
Voice over Ip (VoIP is a service that takes the voice
call traditional used with circuit switching and converts
it into packets that can then be sent over the internet.
Circuit switching requires a dedicated line or frequency
for a call to be setup, conducted and the session
terminated.
This causes two types of problems. It is resource
intensive because it ties up the entire physical path
or frequency all the time whether it is in use of
not because it is dedicated to a single phone number.
Second it ties us to our service provider because
they own the lines or the frequencies. Until fairly
recently you could not take your number with you when
you changed locations for a land line or carriers
for a cell phone.
VoIP solves both of these problems. It is not necessary
to tie up the network or anything except your computer
or WAP (Wireless Access Protocol) phone. You call
is broken down into discrete pieces called packets.
The packets are then streamed over the internet. They
don’t all have to take the same physical route.
Each packet has a sequence number so that the receiving
machine can put them into the correct order. All of
this is transparent to the user.
What it means is this. If you aren’t talking,
there will be no packets sent and if I am talking
at the same time they can send my packets interspersed
with yours so the network is never idle since we don’t
have to have a path held open from me to the person
with whom I am talking.
