i have read through this post and would like to confirm if the latest progression on this release is that a factory reset is required after firmware is successfully loaded?
I noticed the issue resolved itself on the 8831<>8831 phones, but then found the issue reappeared again on calls between 8831<>and other model types(protocol independent). Has anyone else found this same issue?
Not sure if you have you contacted the TAC yet but I would suggest opening a ticket.
We downgraded to sip8831.10-3-1SR3-5-NA as the issue appeared to reoccur with the ES load mentioned and are rebooting the devices regularly (hard reset) as this seems to keep the issue at bay. Otherwise it appears to happen again a week or so after a reboot.
Unfortunately we don't have any spare phones to complete testing and obtain the failed logs for Cisco.
