   SS7 - Signaling System 7

SS7 supports the exchange of special-purpose messages on public
telephone networks. For example, using SS7, telephone companies can
implement modern consumer telephone services such as call forwarding. 

SS7 messages pass over a separate channel than that used for voice
communication. This technique is commonly referred to as "out of band"
signaling. 

Out-of-band communication techniques like those in SS7 are commonly
utilized in computer networking. The File Transfer Protocol (FTP), for
example, communicates out-of-band by utilizing two different channels
and TCP port numbers, one for data traffic and one for "control"
information.

What is VoIP?

VoIP is a technology that allows telephone calls to be made over computer networks like the Internet.
VoIP converts analog voice signals into digital data packets and
supports real-time, two-way transmission of conversations using Internet Protocol (IP). 

VoIP calls can be made on the Internet using a VoIP service provider
and standard computer audio systems. Alternatively, some service
providers support VoIP through ordinary telephones that use special
adapters to connect to a home computer network. Many VoIP
implementations are based on the H.323 technology standard. 

VoIP offers a substantial cost savings over traditional long distance
telephone calls. The main disadvantage of VoIP is, like cell phones, a
greater potential for dropped calls and generally lesser voice quality.
