I wanted to know has anyone out there ever seen where the call history stops working for an entire office. I have an office where the call history stopped on the 18th of Dec and I've even swapped out phones and the call history still doesn't work. I've opened a case with TAC and they've did packet captures and phone log files but he told me he's never seen this before. Any help would be greatly appreciate and thanks in advance and have a great day.
On the latest CUCM releases missed calls is a CUCM service, do you have it listed in your CUCM services with enterprise subscription, which is the default?
The office that you mentioned, does it have phone models of all types or a specific type only? Are these phones registered to a specific server, pointed to specific TFTP or in a specific device pool compared to the other offices where call history works fine? If the exact cucm version and phone firmware versions can be shared then we can check for any known issues.
Were the 7961's upgraded to 9-4-2x using just the firmware files or by installing a new device pack? The release notes for this firmware version do include this note;
Before you install the firmware release, you must ensure that your Cisco Unified Communications Manager is running the latest device pack.
Important:
If your Cisco Unified Communications Manager does not have the required device pack to support this firmware release, the firmware may not work correctly.
I don't see any bugs related to this type of issue in either the CUCM version or firmware version. Hopefully TAC may be able to help here, but I'm guessing because you are on the initial 10.5.1 release they may ask you to upgrade to 10.5.(1)su1a or better yet 10.5.(2)su3.
Sorry man!
Cheers!
