[asterisk-users] MAC Address prefixes of Voip equipment

[Peder]

The first 6 digits of a mac address are the vendor ID and the 2nd 6 are the
unique device ID.  Some vendors use more than 6 digits of device IDs, so
they have multiple vendor IDs.  So 00:0E isn't Linksys, it is 00:0E:xx that
is Linksys.  Some devices use CDP or LLDP to request voice vlan information
from a switch, and some use DHCP to grab various info like vlan, config
files, etc.

Subject: [asterisk-users] MAC Address prefixes of Voip equipment

Is there a database of MAC address prefixes used the common VoIP
devices. I see the Linksys Sipura devices state with 00:0E.

Does the same apply to other Linksys VoIP equipment?

Is there some way VoIP equipment allow themselves to be identified by
requesting data from some ports?
