The
Difference Between Traditional Phone Systems and Voice over IP (VoIP)
Traditional Phone Calls
Traditional phone calls send analog voice signals over public telephone
networks. These voice-oriented public telephone networks are interconnected all
over the world. Collectively, these networks are known as the public switched
telephone network (PSTN). When calls are sent from one phone to another, they
follow a physical path that is dedicated to the connection of that particular
phone call (for the entire duration of that phone call). This traditional method
of sending phone calls is called circuit-switching.
Phone Calls Sent Over the
Internet Using VoIP
VoIP is the process of converting voice from analog to digital and sending the
digital signals in packets over the Internet using the Internet Protocol (IP).
Breaking communication down into packets allows the same data path to be shared
among many users in the network. This type of communication between sender and
receiver is known as connectionless (rather than dedicated like
the traditional phone calls described above).
Most traffic over the Internet uses packet switching and the Internet is
basically a connectionless network.
Key Differentiator in Delivery
Methods of Traditional Calls vs. VoIP Calls
A key differentiator to understand is that in traditional circuit-switched
calls, all resources on the dedicated circuit that is used to transmit the call
are unavailable for other users. Whereas with VoIP calls sent over the Internet
in digital packets, the same data path is shared among many users in the network
and is therefore more efficient than using dedicated paths.
Selecting the Right Phone for
VoIP
Not all phones will work, or are created for use with VoIP. Before
purchasing, check to ensure compatibility
