Please Note: Quadro IP phones firmware control mechanism will not upgrade snom firmware
version from 6.x to 7.x. This should be done manually via snom web site. Once the snom firmware
version is 7.x, the Quadro’s firmware control will automatically upgrade/downgrade the phone to
Epygi’s recommended version but not to 6.x.
Please Note: In the model’s list the Polycom phones with (*) sign are also presented as Polycom-
xx-Pre-3.3.0 due to backward incompatibility of UC Software 3.1.1 configuration. It is
recommended to use Pre-3.3.0 models with Application SIP software 3.2.2.0477.
