Currently, I have two products available. MAC Address Search and VOIP Bandwidth Calculator.
The MAC Address search helps you quickly identify the manufacture of a particular interface on the network. Perhaps you are looking at a DHCP client list and want to know what a particular device is. This feature is often built into most sniffers automatically but there are time when you don't have that tool available. This can also give you a list of the MAC Address Prefixes a company has.
VOIP Bandwidth Calculator is a just that, a bandwidth calculator. It currently only calculates the bandwidth for 2 codec sets (G.711 and G.729). There are time periods when telecom professions need to now how many calls they can fit on a WAN Link or they need to allocate/request enough bandwidth to handle so many calls. This tool will help with either situation.
