Cisco 7940

Hello everyone,

I must to upgrade firmware and to convert my phone to SIP The version I have now is:
App Load ID: P00303020214
Boot Load ID: PC0303010100

I’m confused about what files do I need for both upgrade software and convert to SIP.
I found zip file with these files:
POS3-8-12-00.sb3
POS3-8-12-00.loads
POS3-8-12-00.sbn
POS3-8-12-00.bin
OS79XX.TXT

Is this enough for what I need?

Thanks,
Anya

Anyone?
Please if you know just what files do I need? On every forum is different, somewhere I need also SIPDefault.cnf and SIP.cnf …
