We use Snom 360's and the latest approved Snom firmware is 7.3.27 for Epygi firmware 5.2.9.

Snom only offer 7.3.26 and 7.3.30 for download.

The Epygi tries to push a cromulent version of the firmware according to a setting on the hidden /***.cgi page (as I understand it) but this page is inaccessible - how do I get to be able to see it?

How do I set the Snom phones up (using the snom user interface) to accept the firmware upgrade/downgrade? - the default setting for the URL is http://snom.provu.uk/snom and cannot be changed when setting update automatically.
