I am trying to change the firmware of my 7960 from sccp to sip. I have got a cisco 1760 router which I use as CME4.0 which I use as tftp server as well. This is all for doing some self study for Voice CCNA.

Strange thing I have noticed is that I don’t have SEP-MyPhonesMac.cnf.xml file. But the phone seems to ask for it during registration and strangely enough finds one. On my CME router flash: I don’t see a file with that name. Is it possible for the CME to build that file on the fly and serve it to the phone? I can’t find any documentation either on the web or Cisco books I have to say this is happening. I am more than certain that phone requests and gets this file by capturing packets using VSPAN/wireshark on my 3550 switch which is connecting 3500XL(inline power) where the phone is connected and 1760 CME router.

I would really appreciate if you can comment on this and let me know what is going on.

Many thanks
Salim

It’s really a good idea to own cisco products but of course you’ve got to have a reliable Cisco maintenance contract for security purposes.

Dale,

You can use any TFTP server to do firmware downloads, Windows or Unix based

Do the files on STEP 1 have to be placed on a UNIX server, or can it be installed on a standard Windows computer?
