Some changes that would be handy in my environment.  Please add them?

Observium already supports AXIS Print Servers, Cameras, and Video Servers but doesn't see Video *Encoder*.

sysObjectID=>.1.3.6.1.4.1.368
sysDescr=>; AXIS P7214; Network Video Encoder; 5.50.4; May 23 2014 12:23; 197.2; 1;

fwiw, I don't know if this is useful, but AXIS does publish a Video MIB (which I don't think works with my firmware, ha): http://www.axis.com/techsup/software/video_mib/index.htm

ShoreTel makes some ok VOIP equipment that is SNMP enabled, though it is minimal with info...

sysObjectID=>.1.3.6.1.4.1.5329.1.1.1
sysDescr=>ShoreGear SG-220T1A

sysObjectID=>.1.3.6.1.4.1.5329.1.1.1
sysDescr=>ShoreGear SA-100

Panasonic makes printers (MFDs) too, but the typical jetdirect toner OID reports -3.

sysObjectID=>.1.3.6.1.4.1.258.406.3.1.13
sysDescr=>Panasonic DP-8045

sysObjectID=>.1.3.6.1.4.1.258.406.3.1.13
sysDescr=>Panasonic DP-8060
