[asterisk-users] Cisco 7940 Problem (Mess)

I know this isn't directly Asterisk related. - But I do appreciate the
responses I get from you folks. - At least I don't get flamed like I've seen
on the Java & Perl-Mod lists (geesh!).
Okay - Here's what I've got.
A Cisco (used) 7940 that's loaded with MGCP and I want to load SIP so it'll
work on my Asterisk box (outside of the FXO & FXS modules on the TDM card in
the Asterisk server, I only run SIP on the hardphones).
I don't know the phone's password (sound familiar?). - Have tried
everything, "cisco", "*##", etc.... Nothing works.
So I figured I would set up a .cnf or .tlv (or whatever file MGCP looks for)
with a one-line entry something like 'phone_password:cisco' then let the
phone TFTP the file and reset it's password. - Then I can get into the
'innards' and set up my local stuff so I can upgrade/reload the phone with
SIP and get it ready for my Asterisk box. - Sound do-able?
This is going to be an exercise in 'Networking' for sure.......
The only catch is that per the phone's network settings:
The phone uses a static IP of something like 192.168.0.220 with a Gateway of
192.168.0.1. - Standard class 'C' netmask (255.255.255.0).
The phone has DHCP DISABLED.
The phone has it's TFTP server set to something like 62.120.xxx.xxx
(something completely outside of the local network).
My home LAN uses 10.0.0.xxx on the local side.
But I can reset my XP-Box to 192.168.0.99 and ping the phone with no probs.
But If I set my XP-Box to a static IP of the Phone's TFTP server, my
'SolarWinds' TFTP server sees nothing. - Figured as much as the phone's IP
and my TFTP server's IP are not in the same 'net.
Bottom line. - I've got to figure out a way to build a 'mini-network' so the
phone'll be happy but also set up a PC & TFTP with the same address that's
set in the phone. - Perhaps I can fake-out the phone into thinking it's
hitting a TFTP box on the Internet (????).
I've got plenty of PC's & even a spare Linksys router.
Any ideas. - Or is there something simpler. - Or have I just bought an
Thanks in advance.
