we need urgent assistance for and issue regardinfg 6495 ip phones.
After and upgrade from 8.0(3) to 9.1(2) CUCM, all devices registered in new version, but 6495's. They seem to register but after a short time (no more than 10 seconds) they spontaneously resert and re-start registration, to reboot again at the end, and so on.
6495 are configured as SCCP devices and firmware is 126.96.36.199 SR1.
Shall we upgrade firmware as well? Which version? Any suggestion?
Thanks a lot for helping.
were 6945 phones working with CUCM 8.0(3) or you are trying to register new phones with CUCM 9.x?
if they are new phones which need to be registered with CUCM 9.1, then, u try upload device pack.
you can download the same
readme of 9.3-3SR1
this bug could be the cause.
I suggest uploading Device pack in CUCM 9 and check.
Thanks Aman this what i did yesterday, after a few test, finally I upload to firmware 188.8.131.52 and now all 6945 phones are working. The only problem was that for a proper firmware download to the phone from server, we were forced to shutdown and power up server.
Now I have another issue with 2 7925 phones.
I was told that they loose network connection or AP association (it did not happened with CUCM 8.0(3)), and they are not working. There are as well 2 7921 working with no problems. All 792x have the same firmware 184.108.40.206
