[Asterisk-Users] RE: Howto Setup TFTP server on Linux for Cisco 7960

[Martin Roy]

Get a TFTP for Linux if you use Red Hat or Fedora Core get the server 
there : http://dag.wieers.com/packages/tftp/
it's also available on the install CD...

Then to know what file you need to change your Cisco 7960 phone from 
Skinny to SIP go to this website as it explain how to do it. If it 
doesn't work let me know I did it 2 weeks ago. You have to start with a 
SIP image of version 2.0 or 2.1 if you want it to work. Then you can 
upgrade to 2.2, then 3.x, then 4.x, etc. all the way up to 7.3.

For me I was able to do it that way :

Started with SIP 2.1 then 3.3 then 6.3 and then 7.3. But I had a hard 
time upgrading from 2.1 to 3.3 as the 3.3 image as more then 8 
characters and firmware 2.1 support only 8:3 (8 characters plus 3 
characters for the extension)

If you need any help let me know.
