Connected IP Phones

[#1]

Does anyone know where NetMRI gets its data for connected IP phones?  I see fields for phone model, extension, version, etc, but the fields are not populated for my Cisco IP phones.

It probably gets it from SNMP poll. If the SNMP credential matches the one on the phone, it should populate the model O/S, Vendor etc.

Thanks, but Cisco phones don't support SNMP.
