Change config settings on all IP phones across different network segments - how?

[phadobas]

I have some 800 IP phones (DT700 series), across probably 15 different network segments at my campus. I need to make an audio setting change on all of them (to turn on noise suppression). I could browse to all of them individually, and change the setting, but I have better things to do for the next 3-4 days.
IP Phone manager only works on phones that are on the same network as it's running on.

Is there some way of mass changing these configs?

You could try running IP phone manager at/on each network. However, you may be resigned to doing it individually.

Well, I got a helper to do this for me. She is sitting by a computer, logging on to the phones and changes the settings, one-by-one.

Helper is possibly the operative word here as it jogged my memory but I may be totally off track. You can get information between networks by using a helper IP address, See here.....

I would be interested to know if it helps!
