We have been troubleshooting the exact same issue for almost two weeks. The audio quality and roaming where fine, however the 8821 phones randomly de-registered with CUCM (reason code 12 and 14) and also opening the global address book was sometimes troublesome.
The packet captures shown that sometimes TCP packets from CUCM towards the client where not being forwarded by the wireless network. Due to that the CUCM send a TCP reset or FIN explaining the reason codes. At this moment it is unsure if the root cause is on the controller or access-point side because we have also seen this issue with local switching. I'm also wondering if it only effects CUCM packets and if so why (size, payload, QoS marking?).
We have tested with AireOS 8.3.121.0 and 8.3.121.5 and both are having these problems. Due to that we are now run 8.3.112.0 with the "5 sec audio gap workaround" implemented and the situation seems stable.

We have tested with AireOS 8.3.121.0 and 8.3.121.5 and both are having these problems. Due to that we are now run 8.3.112.0 with the "5 sec audio gap workaround" implemented and the situation seems stable.
Do you have Fastlane enabled?
We're (now) seriously thinking of rolling back to 8.3.112.0 or 8.3.112.7 Escalation Image.

Current plan is to back-out CSCvc78546 via CSCvf31894 which will be provided in 8.3 MR2 Escalation Image.

Thanks for your detailed response! :)
07-25-2017 04:01 AM
Thanks for the update, what about CSCvf29221 which we have ran into?
07-25-2017 04:59 AM
What's the timeline for the next escalation image of 8.3.121.X?

We are also testing 8.5.103.0.

How is your testing going?
We just received the release notes for escalation image 8.3.121.8 which are printed below.
8.3.121.8 is a build from the 8.3.121.0 CCO image and it is an engineering special that resolves the following additional caveat(s). This release can be used with 8821/7925/Spectra link with TCLAS/CAC enabled. In addition AVC/Fastlane can be
enabled.
CSCvf28445 WLC2500 been able to enable multicast to unicast
CSCvf09458 Cisco 2800/3800 series XOR radios are not moving to 5GHz or Monitor mode
CSCvd27398 WLC management access stops working while WLAN services are still up
CSCve06890 Randomly, Wave 1 APs can't send NDP Tx on all channels and can't be found as neighbors on nearby APs
CSCve20123 Corrupt voice packets are observed when a client with an active call does an inter-AP roam
CSCve49741 Cisco WLC fails to send SFTP and FTP when using untagged interfaces on different ports
CSCvf31894 Backout changes - CSCvc78546 that leads to CSCve20123
CSCve76202 WLC IPv4 CPU acl is applied as IPv6 CPU acl during backup recovery or SSO failover
I'm a little surprised to see support for multicast to unicast on the 2504 WLC being introduced in this release (if it is what I believe it is), but why not :-). We embrace the current "stable" situation with our end-customer and will not test this software ourselves.

Testing good, Freerk. The two bugs for the WiFi phones, CSCve20123 & CSCvf29221, seemed to be fine or not present with 8.5.103.0.
I will be upgrading a pair of 8540 in 11 hours from now. We'll see what happens.
08-03-2017 11:57 PM
Still running with the new version? :-)
08-04-2017 05:11 AM
Yes, a pair of 8540 on 8.5.103.0. No wireless voice issues observed.
08-06-2017 07:59 PM
I have had -lots- of serious issues with 8.5.103.0 and that was in just a lab environment with no voice. The worst were serious problems with my SGS8 phone and other Android devices disconnecting, and other issues relating to AP side disconnects with client side staying up (but with no connectivity).
8.4.100.0 has been my goto fallback release though which has been very good so far, but unfortunately it appears that 8.4 is probably only going to have a short lifespan. The focus seems to be on 8.3 and 8.5 stability instead.

Release 8.3.122.0 is a repost of Release 8.3.121.0 with the inclusion of three caveats in the Resolved caveats list.
There are no other updates in this release, all resolved and open caveats in addition to three resolved bugs apply to this release.

I installed latest 8.3/beta (coming from 8.2) in my prod environment and found an error displaying AP capabilities with 1262 (we still have a lot of them):
