I have 7942 ipphone, which keep shows upgrading after factory reset, but unable to download the firmware load from cucm tftp. could any body knows how to fix it. My cucm is 7.0.2.below is my load info for 7942
Any clues for the fix??????????? tftp is reachable, otherwise many phones will behave the same way!!!!
I have 149 nos. of 7942 ipphones. One of them was registered earlier & taken off. When I plugged it again it went to endless "term42.default" load upgrade.
then i resetted it to factory default but same outcome popped-up.
I am unable to reach beyond that upgrade, rest of the phones are working fine with factory reset (like 7940,7941,7961,7960,7945,7985).
the load i have for 7942 is "SCCP42.8-5-2SR1S.loads". I cant tell you app/boot load id as phones doesn go beyond upgrade. keeps showing "dot inside a circle" on bottom left corner of screen. So as sniffer & snapshot is not possible.
Can you please tell me the steps where to start from. which load iamge should i download.
One more thing i havent checked resetting another 7942 to factory defaults in order to check the behavior.
I dint understand why a sniffer is not possible! coz, all you need to do is put a laptop or PC on the PC port while its trying to upgrade, and run wire shark on it, so what i would suggest is to put a laptop on the PC port of the phone, run wireshark, plug out the phone, and plug it back in, this way the phone would go through its boot up sequence, and we would be able to see in the sniffers, wats goin on with the phone.
To go for an step upgrade please put cmterm-7942_7962-sccp.8-5-2.cop.sgn file on the call manager (all servers), heres the link to download the firmware:
ones the firmware is on the call manager, and you can see it in the device defaults for the phone, restart the tftp services, and then try registering it agian.
Regarding the application load, i did not understand, if the phone gets an IP or not? is there no way to check, may be on the switch?
If you get the IP, please put the IP in a browser as https:// and you should be able to see the load.
the step upgrade to 8-5-2 should help, If upgrading to the 8-5-2 load does not help, n we are unable to get a sniffer, i would suggest you to open a TAC case, it will be much easier to troubleshoot if we have access to the system.
