• SIP enables the implementation of intelligent endpoints to support scalable advanced

services.

In a nutshell, SIP is a distributed signaling protocol (as opposed to a centralized protocol such as

SS7, MGCP or MEGACO/H.248). With a distributive protocol, the intelligence does not necessarily

reside on a central server, but can be built into the individual endpoints. By moving the intelligence to

reside within the endpoints at the edge of the network, the processing load of the network application

and associated call servers are significantly reduced, thus making the network a very scalable

solution.
