[cisco-voip] Cisco IP phone and infinite DHCP lease

[Anthony Kouloglou]

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

Regards
Anthony
