we have some problems with the configuration of background image, because in our scenario, we have a Voice Vlan and a Data Vlan.
I used a Web server into the Data Vlan, but it's not alway avaiable for the phones, so it losts the picture.
Also, I tried to put the image on a website, but our Voice Vlan has restrictions and again I can't get the file.
You should add an Upload Form to change the background (like in web management of phone I already Used, es Yealink T46S), just like the file upload also avaiable in the account, or in the phonebook page.
Also a good features I found in Yealink T46S, is the Screen Saver, where I can upload several images (again, via upload form).
Thank you for the feedback.
It is also possible to upload a background image via Branding, see more information here: http://wiki.snom.com/Category:HowTo:Branding . This would allow you to upload the image only once and then it would be saved on the phone.
I've just read the guide on Wiki, but in the example, there's no link to the D785 archive.
I've tried to dowload a different TAR, but I see a lot of reference to the specific phone (820).
Can I use this archive on D785 ?
By the way, this procedure is not easy and fast as on the Yealink for the scenarios in which we install the phones.
Also a features like a screen saver would be tempting for customers who have spaces open to the public.
I am attaching an example tar archive for D785. You will need to replace the picture in the archive with your own and re-create the archive. Once you have uploaded the archive, don't forget to adjust the transparency for the background under Preferences -> Appearance -> Background color (decrease the fourth value for example to 40, or 0)
We don't have a screen saver but maybe the demo mode could be something interesting for you: http://wiki.snom.com/Version10_Initial/Features/Demo_Mode
