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!

5¢ please  :-)
