Is there any way to force company wide one background image?

I am using CM 7.1.3 and 7945/65 phones

I can get the image into the List.xml. The only way I see it is to edit the phone firmware default file, but don't know How? or any other suggestions??

I have seen this come up a few times and I have seen folks recommend Cisco Phone Designer.  This is an application Cisco offers for free download.  It allows you to customize ring tones and screen background from an easy to use interface.  Unfortunately, it is a user tool not an admin tool.  Meaning, it only allows you to push to one phone and not to all phones, which I think is what you are looking for.

That being said, the Cisco Phone Designer tool uses an API method on the Cisco IP phones that you could try to tap into.  The method is called "setBackground" and I believe it is an undocumented method.  I stumbled across it by perusing the Cisco developer forums:

Basically, you do a HTTP POST to the following URL:  http:///CGI/Execute.  The XML you would use in your POST transaction is:



I have tried this out and it works as advertised.  You have to make sure that "Phone Personalization" is enabled for the device(s) you wish to modify.  Of course, you will also need to develop a script/tool to push the changes to the phones.  If you are comfortable with scripting then this isn't too difficult.  If you aren't comfortable with scripting then you may need to pull in a resource who is.

Right now, I am not sure of an alternate method to force a phone to pull a specific background.  I have looked and I had to resort to writing my own method using info from the link I provided above (and some trial and error).

Thanks for your answer Bill, but I am looking to change force the image company wide (15K phones).

If you asked if there's a magic button to do this, the answer is no.

However, I think Bill already explained it clear - this can be done if you write a script to do the same thing for 15k phones.  Or you can pay somebody to write the script for you.

Check out the 'Background Deployment Tool' from Voip Integration.

It's fairly basic, but does what it promises. The main downside for me is it only works on the large screen phones, and not the 7906/11 handsets.

Good value for <£100 though. We bought it, for use with our (currently!) 400 7941/42/61/62/45/65/70 handsets.

Yes. And you can force out cluster wide, to a single device pool, or to individual phones.
