CUCM 6.1(2) - 7961G and 7970 phones crash after user logs out
We are planning to roll out CUCM 6.1(2) in a few weeks. Im sorting out some final testing, and have noticed that our 7961G and 7970G IP phones crash every 4th-5th time i log a user out (using Extension Mobility).
I have tried to crash a 7960 in the same manner but i cannot.
The 7961G and 7970G just freeze with the Ext Mob details (ie phone number) of the user i have just logged out on them. I have to power the phone off to get it to be useable again :o(
Model number: CP-7961G
Load file: SCCP41.8-3-5S
Boot Load ID: 7961G_64-02070631Amd64megRel.bin
Load file: SCCP70.8-3-5S
Boot Load ID: 7970_6406118.bin
7960: (I cant get these to crash - they seem fine)
Model : CP-7960G
App Load ID: P00308000800
Bott Load: PC0303010200
We are using the Device Loads that came with CUCM 6.1(2) so i assume they are ok ?
Anyone got any ideas...? Im on the verge of raising a TAC case thru Cisco because this is most odd.
Could there be a dodgy Ext Mobility setting somewhere that i need to check? Ext Mob and TFTP are running ONLY on the Publisher at the moment.
Are you getting this error “Installer User Interface Mode Not Supported. The installer cannot run in this UI mode. To specify the interface mode, use the -i command-line option, followed by the UI mode identifier. The value UI mode identifiers...
The below trick might come handy when you have to add a new node to a cluster but you don't have or is unsure of the security password for the publisher. This procedure has been around for ages.
1) Login into the CLI of the Publisher.
