Obtaining brand-new equipment/components is nice—but the design in how these technologies are deployed is just as critical. Putting a new router in place does nothing if that router doesn't have the capability to handle thousands of voice calls, if that is your current volume of PBX traffic.
New technology in the network is great if that technology has been designed and selected with convergence in mind. Also, replacing the infrastructure, even if it is a nice idea, lengthens the ROI timeframe. These factors should be considered when looking at new technology. A VRA, for example, might expose that a couple of edge routers need replacing—but not the entire infrastructure. The following section reviews some ofthe common misconceptions about IPT deployment.
