lgia that is reserved for looking at candlestick phones today. SPs see a great benefit in their capability to see across all their assets with IPv6 networks. Today, as networks have evolved from multiple protocols and transports to a more homogenous set of protocols, SPs can better diagnose and monitor their network. The end result is increased efficiency as fewer resources are needed to monitor large net- works; for instance, it is easier to troubleshoot one routing protocol than multiple ones. Unfortunately, due to the inherent limitations in IPv4 networks, there is little or no capa- bility to see the routing and underlying infrastructure and health between networks. Each private 10.x.x.x address space must be examined and monitored independently. IPv6 can resolve this for SPs by creating a routable address space across a large network. This large address space can be monitored in a holistic way enabling SPs to see what is going on throughout their network with a single set of extensive monitoring tools. This increase in efficiency will enable them to lower their costs and pass the decrease on to the consumer in the form of lower prices. This, in turn, will enable for the expansion of bandwidth and enhancement of the UC experience. 308 SIP Trunking The Power of Revolution: The Greening of Unified Communications An important revolution that will have a major impact on UC is the Green revolution. There are many definitions of what the Green revolution means and where it will go; how- ever, one thing is clear: UC solutions in the next 40 years will have to consume less power for the same experience as UC solutions today. The primary component of voice communications, the phone, has a reasonable power consumption profile. The sheer volume of production led companies to innovate in the area of battery life. However, the primary components of UC include video, and it has not yet had the same focus for power optimization as voice has undergone. Improved screen technology that will consume less power and be more perva
