Recently we found that the call history would disapper on the 6941, and it could be resume by reset the phone. When I look into the status message of the phone, it gave me the full page of "MGB_DM_ERROR_INDICATION (Channel-Independent): Error: 209, Module:1, triggered_by_msg_id=2085".
I don't know if this is related to the issue or not, but when I search from the web and found that the error message might come from the bug CSCtf81666 which fixed in firmware 9.1(1). The problem is the phone is using the load 18.104.22.168, and it should be fixed on this load...
CUCM version: 8.03-20000
69XX phone load: 9-2-2-6
There are a couple of issues of this nature
Please upgrade the firmware to 9.3.1 to resolve this issue.
Hope this helps!
Thanks for your information.
We just upgraded the phone load from 9-2-1 to 9-2-2-6 due to another bug issue not very long time ago, and we got another bug issue before that... If I told them this is another bug issue again... they might kill me...
But anyway, Thanks !
You may be nice in willing to spare your customer another update, but the about 20 bugs still present in the firmware you are running might play not so nice and hit them anytime
