In VoIP, a signaling Protocol handle call setup, conversion of phone number to IP address mapping and proper call terminating . It usually involves the user location phone number , finding route between a caller and a called party . It also handle things like all forwarding and other call features.
IP telephony signaling can either use a distributed or a centralized signaling scheme.
In distributed signaling scheme, it enable two IP Phone to communicated using a client/server model. It works well with VoIP network within a single company. In a centralized approach, it uses the conventional model and provides some level of guarantee. Signaling is usually done between two IP phones and each phones will exchange those packets to ensure there is a communication link.
In the next section, we are going to look at different types of signaling protocols used in IP telephony.
