First, my tftp server is a Linux box and my tftp directory is
/tftpboot (setting can be found in /etc/xinetd.d/tftp if your using
xinetd such as Fedora is).

Next, I get requests from the 7960 (similar phone) running the
SIP image (I've tried v5, v6 and I'm now on 7.4). I get the
following files requested when the phone boots up:

CTLSEP000ABCD01234.tlv
SEP000ABCD01234.cnf.xml
SIP000ABCD01234.cnf
MGC000ABCD01234.cnf
XMLDefault.cnf.xml
SIPDefault.cnf
SIP000ABCD01234.cnf
P0S3-07-4-00.loads
P0S3-07-4-00.sb2
RINGLIST.DAT
dialplan.xml

Note that 000ABCD01234 is a made up MAC address, replace it with your
phone's MAC address. It also requests the files listed in the RINGLIST.DAT.

Take a look at:

They have lots of info (you'll still have to do some work). Sorry I can't
give credit to the person who create all this but I'm sure they're
on this list (that's where I found this info).
