The problem on those ATAs is that there are no users but emergency
analog devices attached on them :-(.<br>
I have tested in my lab with a 7941.<br>
Even with an infinite lease, when i reseted it remotely, it got a
new ip from another dhcp server.<br>
But ATAs is another case.<br>
I will try to find one for a test.<br>

</div>
<div>You can always ask your users to do it, or local IT focal
points if you have them, assuming you are changing away from a
infinite DHCP setting, you would only have to do this once I'd
expect.</div>
<div><br>
</div>
<div>I'm afraid I haven't used the ATA's in quite a while, so I'm
a bit rusty, but I believe you could change the ATA from DHCP to
static (keeping the same address?), apply and then swap back to
DHCP again. The details on the ATA web interface are here:</div>
<div><br>
</div>
<div><a moz-do-not-send="true"

<div><br>
</div>
<div>Obviously you need to test this as you don't want to make the
situation worse by having ATA's you need to manually factory
reset :(</div>
<div><br>
</div>
<div>Also,</div>
<div>It is possible to remotely control multiple phones at once
for this type of problem, we released an application called
PhoneView at the beginning of the year that's 100% focused on
managing phone endpoints, on the basis you never need to
physically touch a phone again (as long as it's registered with
UCM, SRST or CME).</div>
<div><br>
</div>
<div>I suggest you have a look at the video(s) on the website to
see how it works (<a moz-do-not-send="true"
href="http://www.unifiedfx.com">http://www.unifiedfx.com</a>),
in addition for key press macros there is a video with a good
example on this, in this case for the bulk delete of ITL file
from multiple phones here: <a moz-do-not-send="true"
href="http://www.youtube.com/watch?v=f7oPuj1szNg">http://www.youtube.com/watch?v=f7oPuj1szNg</a></div>
<div><br>
</div>
<div>Note: There are some really ground breaking enhancements in
PhoneView Version 2 that will be released on in a few weeks that
no other remote control based product can do, it might be worth
your while registering for the Webinar: (<a
moz-do-not-send="true" href="http://events.unifiedfx.com">http://events.unifiedfx.com</a>)</div>

suppose a ip phones (79XX, ATA186,
