I'm a little out of my element here I will admit. We have a very old InterTel system i'd say from 2000-2001 and one of the managers has had one of these 770.4500 phones at his home for quite some time, a few years back it stopped working because the IP settings are completely incorrect on the phone for our VPN, etc. No matter what I do i do not seem to be able to change any of the settings.

I've tried.

hitting 7 & 8 while the phone is booting
holding 7 & 8 while the phone is booting
telnetting to 192.168.200.202
-the session connects but then drops
web browsing to 192.168.200.202
-a username/password screen comes up and conviently nobody here knows what the password/username is.

if anyone knows how i can change the IP/subnet/gateway on this thing I would be really appreciative. E-mail or PM me or simply post here if you have any ideas.

thanks.
