As ever I try and bring you guys (and girls?) something a little different :)
After completing this video here and being in contact directly with PRTG it came to my attention that the version I was using "PRTG Traffic Grapher V6" was EOL and the new version "PRTG Network Monitor" is the successor.
Network Monitor does have alot of cool new features including an iPhone app (cant wait for a droid version) and the best bit...they were kind enough to provide me with a copy of PRTG Network Monitor V7 for this video.
A cool tour of some of the features of PRTG Network Monitor V7 and how we use our virtual machine to monitor our voice network
This video actually shows you how we set the whole thing up!
