I have been searching cisco.com and some other forums in regards to this but can't find an answer.. Hopefully someone can help me out here.
I got a Cisco 7940 with SIP firmware, SIP V. 8 and I would like to convert it to SCCP.
I have downloaded the latest SCCP version 8.11 from Cisco.com and then copied the files to TFTP server.
Please note that I'm not using any Call Manager application. Based on Cisco documents, I used this one:
If I upload the firmware files, OS79XX.TXT and SIPDefault.cnf to TFTP, the phone should convert automatically to SCCP. But it won’t.
I have uploaded the following files:
In SIPDefault.cnf I have changed image_version: to image_version: "P00308010200"
OS79XX.TXT: One line and that's: P00308010200
The TFTP logs show that the phone is requesting SIPDefault.cnf and downloads it but the phone still won’t convert to SCCP firmware. I dont see it requesting OS79XX.TXT though.
I have also telnet to the phone and use the erase command to re-do the setting... but no luck
Thanks for your help
Solved! Go to Solution.
I don't think you can go straight to 8.1.2
Your best approach would be try 7.x or 8.0.10 first, make sure you do a factory reset anyway.
Thanks..I downloaded the SCCP V 7.. P00307020400.bin upload all files to the TFTP... changeed OS79XX.TXT and DefaultSIP.cfg (image_version: "P00307020400")
reset the phone to factory default.. Still SIP protocol/settings
the SIP version is actually P0S3-08-8-00
I see in the TFTP log that the phone is trying to download SEP
Do I need to specify the firmware there?
I also tried with P00308000100.bin still it just wont do it...
if you have CME, configure and ephone with that mac-address, configure load under telephony-service.
I was using SIP and works great but then I purchased 7914 Expansion Module not knowing that it won’t work with SIP. That’s why I want to change it to SCCP
What do you mean by reset sequence?
I did that.. I first tried 7.4.. now I treid 7.0 but it's the same thing.. won't upgrade it...
I just used another TFTP server.. thought it might have something to do with TFTP server...still the same...
I was actually watching the screen on the phone now, and at the part that says "requesting configuration" right after that I saw "No Load Specified"
I'm gooling now to see what that means but let me know if you ever came across that...
In os79xx.txt, try Pxxxx.bin or .loads instead of no extension.
You should not see SIPxxx fetched after a factory reset.
It may be kept in SIP mode despite the reset sequence. So the only way is to give it what he wants.
Finally... I had to add
Thanks for all the help.
