Hello @MarcosF ,


Welcome to the Poly Community.


I can see the following internally:


64167F1502D4 28/03/2017 Veracomp SA
64167F150271 28/03/2017 Veracomp SA
64167F28a542 11/01/2018 WESTCON-CANADA


As these are all from different years I would assume these are different hardware revisions.


Are they used in a very specific way aka a call centre or are these cleaned using cleaning products?

Good morning,


Thanks for replying! In regards of your questions:

1. We don't have a call centre

2. The polycom are not cleaned at all. Whenever is dirty, I just clean it myself using a dry papertowel or cloth.


Thanks again!
