Building a strong case for SIP implementation
The benefits of SIP are well-known to many engineers and administrators. However, providing a true ROI for such implementation might prove to be a challenge without the proper tools for calculating SIP bandwidth requirements. In the past, well worn methods of traffic engineering were used to plan voice networks. For a properly set SIP environment, you need to engineer the network at each phase of the deployment by calculating the number of concurrent voice channels needed.
In "Building a strong case for SIP Implementation," learn the necessary steps you should take in order to not make the appropriate calculations, but also how to create the ROI model for SIP trunking.
