Editing the OUIFilter.cfg file
Modified on: Mon, 16 Jan, 2017 at 2:45 PM
Delete the last three octets (last six characters) of each phone’s MAC address, and you will end up with a list of the first half of all of the MAC. The first three octets of a MAC address is what is called the “OUI” or Organizationally Unique Identifier. This identifies the hardware manufacturer of the device. If you want, you can look up the manufacturer on the IEEE website (they manage this list globally for all Ethernet adapters in the world):
If you eliminate the duplicates on this list, you will get down to a short list of OUI entries that match “what phone OUIs exist on your network”. This is what PathSolutions will look for to identify a device as a VoIP phone.
If you go into the C:\Program Files (x86)\PathSolutions\TotalView directory, you can open the OUIFilter.cfg file with Notepad. Paste these OUIs into the file and add a character and “thephonemanufacturer” as the description. Save the file and then stop and restart the service. When you go to the Phones tab and click “Update”, these are the OUIs that we will look for on switch ports to say “there’s a VoIP phone here”.
Note: If you know you won’t have any other manufacturer’s phones on your network, you can eliminate the other entries in the OUIFilter.cfg file from the configuration if you want.
