I have about 1000 9971's deployed running firmware 9-3-4-24 on CUCM 8.6
I have intermittant issues with individual phone(s) going unregistered, display on the phone says "registereing", phone can still be ping'd and I can still access phone URL / web page. Only fix is a hard re-boot. Anyone else experiancing this issue.
Have some phones where DTMF tones are NOT passed when on speaker phone, bur DTMF tones can be passed if user swithces to handset whle on the call.
I think these are firmware issue(s) but TAC has not been able to help and i just want to know if anyone else has had similar issues. I have had alot of buggy type issues w/the SIP 99xx phones, very frustrating.
Considering the different kinds of issues you are experiencing with 9971's it would be a good idea to upgrade a few of the affected 9971's to the latest firmware 9.4(1) and monitor them for a couple of days
