I have a program that searches for MAC address prefixes to locate where devices are connected on the network. It would be valuable to my customers to be able to locate Cisco VoIP phones, but I need to know the MAC address prefix of some Cisco VoIP phones to be able to locate them.
What Is the MAC Address Prefix (OUI) of Cisco VoIP Phones?

I think Cisco uses 0002b9 for their phones but 000e08 and 0016b6 may show up for any Sipura/Linksys devices.
