To upgrading software of Roomkit+ device, I had found the software on cisco homepage.
But I Couldn't find the *.pkg file that can upgrading on device administrator page.
There are only *.sgn files available.
As far as i know, *.sgn file can only apply through CUCM Infra environment. But I don't have that.
So I'd like to upgrade software on web administrator page instead of CUCM.
How can I do that?
