Signal	A signal is the representation of information through the value or value pattern of a physical factor. A signal whose parameter represents a message consisting exclusively of continuous functions is called an analog signal. If the signal only consists of characters, on the other hand, it is called a digital signal.
SIP	The main purpose of SIP (Session Initiation Protocol) is to initiate and terminate interactive multimedia sessions, such as voice, video and chat. One of the most attractive features of SIP is the redirect, which makes it possible it for users to initiate and receive communication and services from any location, and for networks to identify the users where ever they are.
