You probably do not need firmware. I have tried several versions on
70s, 60s, 12s, 05s and 20s (not 02s) with success.
If they are not even looking for TFTP, then from the phone, hit
Settings-2**#, and erase. Make sure your DHCP server is kicking out
option 150 right (the correct TFTP server) - if it is Linux, you will
need to create several symbolic links due to the differing upper/lower
case requests from differing phones and firmware versions, but the
XmlDefault.cnf.xml should get them going fine.
Do a tcpdump from the server to make sure they are actually requesting
the files.
Setting-2 should list the correct DHCP / TFTP servers.

I understand that I must pay for a support license to download Cisco
firmware, so I’m not trying to pirate it. I simply want to know what I
need to buy in order to get firmware files for my phones. Does anyone
have any helpful links they can give? What does this license cost?
Specifially, I need SCCP images for the 7902 and 7940… Does anyone
have any experience with setting this up and can either give me a hand
or point me in the appropriate direction? Most of the entries on
voip-info.org were pretty light on details, just postings of different
config files. Also, if I’m just doing skinny (no need for SIP, and the
7902s don’t support it anyway) do I even need firmware files? It seems
like I do, but I can’t even seem to get my phones to try to tftp in
and download anything.
Also, for anyone who has used either of these phones, how well do they
work with asterisk? The chan_sccp2 drivers say they “mostly work” but
I want to know what doesn’t work to see if I care. Any help would be
appreciated, thanks.
