CCMPhonesCiscoData Table question

Trying to understand some data out of a SWQL query better.  Specifically in the orion.ipsla.ccmphonesciscodata table.  What do the values in the ProductType field represent?  Is that to be an indication of the phone model?

Query I'm using is:
SELECT TOP 1000 ID, CCMPhonesID, Index, LastRegisteredUTC, Extension, IpAddressV4, ProductType
FROM Orion.IpSla.CCMPhonesCiscoData
order by lastregisteredutc desc
