I would like to know if anyone have been experiencing some freezing issues with 88XX phones?
We first received the phones with the firwamre sip88xx.10-2-1-16 but since the phone was looping through reboots when connected to 2x or 3x 8800 modules, we upgraded to sip88xx.10-2-2-16. Since then, the phones freezes completely from time to time and needs to be disconnected.
When frozen (which often happens when the calls are transferred to another extensions), there is nothing we can do at all on the phones.
There is no newer firmware so I'm pretty much stuck here.
I'll have to try our other BNIB 8851 but at least one 8861 and one 8851 have the exact same behavior.
For those of you keeping score at home -
Active Load ID sip88xx.11-5-1SR1-1 (Current FW)
Inactive Load ID sip88xx.11-5-1-18 (previous FW) Cisco 8861/Freezing issue
Inactive Load ID sip88xx.10-2-2-16 (previous FW) Cisco 8861/Freezing issue
Inactive Load ID sip88xx.10-3-1-20 (previous FW) Cisco 8861/Freezing issue
User reboots the phone and will temporarily resolve the issue; I am on a CUCM 8.6 cluster
We got firmware version 11-5-1ES-13 from Cisco Support about a month ago to resolve our freezing/reboot issues on the phones. It appears to have resolved the issue for us. Hope this helps.
