Telecommunications & Voice over IP (1 Day)


Introduction:

Voice over IP (VoIP) has finally come of age. With improvements in broadband services Quality of Service, Digital Signal Processors, compression and other related technologies the road is finally clear for this exciting and new telephony technology.

Telecommunications costs have always been an issue for both provider and subscriber. The volume of both voice and data services has been steadily increasing. The POTS (Plain Old Telephone System) with its' circuit switch technology' is being stretched to it's limit. POTs will give way to a new convergent technology where both voice and data share the same path, and at the same time. Much like the Internet, voice will be broken down into packets and transmitted to its' destination.

This one day seminar, focus' on the understanding of traditional and IP telephony transports including signaling protocols and voice and data convergence. Finally this new technology (VoIP) is able to approximate the traditional telephony in terms of voice quality and reliability.
