I got five of these doctor's phones as well.
You need your server set-up with dhcp and tftp. In the tftp directory,
you'll need files SIP<mac>.cnf and SIPDefault.cnf available. You'll
also need the current SIP firmware load.
Then, you have to let the phone power up, then enter the password
'cisco', the go to settings->3->28 (remove config) and also ->25 to
enable DHCP. Then hit 'yes'.
If your files are ok then the phone will reboot, upgrade its firmware,
and read the new configuration.
I performed this procedure five times this morning and it worked every time!
5ยข please :-)

I just had to do one the other day; the phone shipped with mgcp installed
with some Doctors name appearing on the screen. It had been locked down
pretty tight.
The only way that I could do it is to use a sniffer (eg, ethereal) to
see the IP addresses it was trying to reach.
I then put the phone on a network that had a linux server with that
exact addressd on it. The phone happily read the tftp files that I
had prestaged on the linux server, and upgraded itself to the sip image.
The upgrade process wiped out all passwords, etc, and reset the phone
to factory defaults for sip (except for the password, which I specified
in a tftp config file).
Once that was done, I could access the phone menues just fine and reset
everything to the way that I wanted it.
If you're not comfortable reading packet traces, then you'll probably
have to send the phone to someone that is.
