Hi Stephen,<br>
the problem is that i don't want to go to every phone and press that
sequence.<br>
How is it possible to do it remotely? (with that for example? <a href="http://www.voipintegration.com/Software-Phone-Remote.aspx">http://www.voipintegration.com/Software-Phone-Remote.aspx</a>)<br>
As far as the ATAs, what you thing would be enough to do via the
webgui?<br>
<br>

<div>I suspect if you go to the phone settings and erase the

<div>If that worked it would give you the option of using a key

<div>This would only apply to the normal IP Phones, the ATA's

suppose a ip phones (79XX, ATA186, ATA187, 69XX)

If i disable this dhcp and set up a new one with
