Hey Jason, a lot of the Cisco phones (all maybe) support LLDP. I was reading
a juniper article the other day about their switches supporting/configuring
LLDP and a long list of C-Phones that would work with that configuration. As
for other phones support for LLDP I wouldn't now where to begin. This is a
good article in general but please not that it is J-Centric.
