This also leads to the importance both of the network infrastructure, including local and wide-area networks, and of providing end-to-end quality of service to support voice as a real-time service. Suppliers are striving to develop the systems that will exploit the new converged world while at the same time deliver the reliability and functionality that customers demand. It is currently very much an early adopter market for these IP telephony solutions and experience drawn from delivering trials to external customers as well as the internal pilot work is used to provide. a practical snapshot of today's solutions.
