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
Cisco 8861 FW Version - sip88xx.11-5-1SR1-1 seems to have resolved the issue. Thanks for the response Rob; This FW was released as of November 2016. For any others looking, the cisco repository I downloaded the current version from is in the link below.
I am using sip88xx.11-5-1SR1-1 on an 8841 and have had a few freezes when switching lines or coming in and out of voicemail. It isn't consistently happening, and has only occurred a few times. Never had any problems with the previous 11-5 firmware.
What I am experiencing is a screen freeze, then an off-hook dial tone that will be heard whether the phone is on or off hook. Pressing buttons has no effect. After about 30 seconds it seems to correct itself and go back to normal.
Sadly 11.7(1) hasn't fixed the problem, it does indeed appear to be a memory leak, the phones have to be in use for 2 or more weeks (without reboot) before the freezing starts intermittently manifesting itself.
It would appear that despite being out for over 2 years, the 8800 series phones still aren't stable enough to replace the 7900 series.
Facing same issue with a customer. 8851's with Expansion modules and without expansion modules occassionally are stuck on screen/ keys unresponsive. Have opened TAC case and will try collecting packets from the phone and switch.
CUCM version # 10.5.2.12901-1
Sample Phone Model # 8851
Phone Active Load : sip88xx.11-5-1SR1-1
Will update if we find any solution.
