I have got a Cisco 7940. I want to use it with SIP account. Can you help me to insert the SIP firmware?

You can delete it in CUCM (since it's currently a skinny phone) and readd it as a sip phone. After that, you will likely have to do a factory reset on the phone. You do that by power cycling it and holding down the # key. Wait for the lights to cycle on the Headset, Mute and Speaker buttons. Once the lights are cycling, press buttons 1, 2, 3, 4, 5, 6, 7, 8, 9, *, 0, # in that order. The phone will reset it's config, contact the DHCP server and start to download the firmware image from CUCM.

Hi
I recently bought a brand new 7940G phone off ebay from a registered Cisco person who also supplied me the SIP firmware files so I can convert the phone to SIP because I am donating it to a charity and setting up a new network for them and running 3CX phone. From all the things I read it should be possible. This should help you Stefano but I still have not completed it to a working state so hope someone else can help too.
OS79XX.TXT and
SEPMacaddress.cnf.xml

The phone said "Loading software" (from memory)
On the phone I got an error that said something along the lines of "TFTP Size error P003-07-5-00" (from memory)
Then it just continued looping as shown above.
Can anyone please help me by suggesting what I can try next. I have burnt the midnight oil on this for the last week or so and really do not want to give up and buy dearer phones. Interestingly I bought a Yealink SIP phone and it worked within one minute on the 3CXPhone IP PBX which is running on the Small Business Server.
Maybe I should have bought the 7940 already changed to SIP!
