Mass config change with hosted VOIP provider

[charper]

Hi,

I am deploying several T46G phones onto a hosted PBX called Jive (http://www.jive.com). Jive offers a provisioning server which I think is definitely the best way to get the phones connected into that system.

However, I'd also like to be able to edit the phones' configuration all at once.

For example, I'd like to be able to upload a wallpaper image to all phones at once and perhaps make some tweaks to the soft keys. I know this would be possible if I had my own provisioning server, but is there any other way to make similar edits to multiple phones without individually logging into each one's web interface?

Thanks!
Chris
