Trio 8800 Firmware AA AB AC AD AE AG

Hi All

I am a little confused about firmware updates of the Polycom Trio's

Polycom list the same software levels with different suffix's, AA AB AC AD AE AG

AA appears to be for Phone Only, AB for units with Visual+


We purchased Trio 8800 with Visual+ but due to network config issues we are at present only using them as an Audio Phone only

The latest update 5.5.4 is AA only, I was on 5.5.3 AB (not sure if that is correct)


Can anyone explain the difference

Thanks in Advance
