Mitch, EoL doesn't matter. End of software maintenance is October this year. Also, if the bug is on the WLC side Cisco would still need to fix it. The 8821 has had some buggy software up until now. (and still does compared to the 7925g)
05-22-2017 06:22 AM
I'm going to upgrade tonight. I'll have more information tomorrow as to if our 7925g phones work or not.
05-23-2017 07:03 AM
Genesis IT-
So far so good on our 7925g phones with 8.3.114.74. We're running phone firmware 1.4.8.4.LOADS to an 11.5 CM environment. I do know that earlier code like 1.4.4.xx on the phones doesn't work for us. We're also using PEAP to RADIUS with CCKM enabled FWIW.

Just wondering if you still experienced 7925 one-way audio and registration issues on 8.3.121.0 or 8.3.121.4? We upgraded our 8540/8510 to 8.3.121.0 and 8.3.121.4 (esc image) a couple weeks ago and we still have random one-way audio on 7925s and phones appear as "rejected" in CUCM and say "Configuring CM List" on the phone screen. Debating on moving back to 8.3.112.2 (esc image). Unfortunately, we have to support AeroScout RFID and 2802 APs together in our environment, so anything older than 8.3.112.2 is not an option.

I'm running 8.3.121.4 on a pair of 8540 and the 7925G phones are not able to join CUCM, however, an 8821 is able to. Weird.

Cisco TAC was able to reproduce the problem that we are having with 8.3.121.x. From their testing and packet captures, they were able to see that TCP packets from CUCM were being dropped by the controller and the phone just kept re transmitting TCP. This was causing our phones one-way audio and deregistering from CUCM. TAC is going to file a new bug with their development unit, but in the meantime, they have suggested we roll back to 8.3.112.7 (esc image). If you have 7925/8821 and 2800/3800 APs and need version 8.3.x, I would NOT recommend ANY of the 8.3.121.x train due to the VoWLAN problems we've experienced. I hope this may help out others that might be having the same issues.

Right-o. Thanks for the update. Rated the post so others can take notice.
Kindly update us with the Bug ID when it's available.

Downgraded our controllers back to 8.3.112.7 last night and so far this morning, 7925s/8821s are operating as intended again.
The BugID they created for our VoWLAN issues on 8.3.121.x is CSCvf29221 but it's not yet publicly available.

Does anyone know if the 8.3.112.7 image contains the fix for the 3800s randomly dropping location information to the Aeroscout location engine? I'm currently running 8.3MR2 because of this but finding that we are running into the one-way audio with the 7925s in the areas with APs attached to that controller.
On a side note, I'm glad TAC was finally able to identify the issue, the case I had opened on this issue unfortunately didn't go anywhere.

Genesis IT. Describe your RTLS issue some more. Do you just see that doing a 'show rfid detail < mac address > the 3800s don't report a value randomly? I haven't noticed 8.3.112.0 having RTLS issues, but I just have a few at my desk. Our entire hospital is now on 8.3.112.0 as of yesterday, but our new hospital clinics with 3800s won't over for a few more weeks.
Also, thanks for pointing out that one-way audio issue early. I didn't see it when you did, but when we jumped to 8.3.121 it was horrid. We lasted a day and had to roll back like you did. My tac engineer took all of my captures up to the BU and they could duplicate the problem.
I can't believe that an MR2 release we can't run because a Cisco phone won't work with a Cisco network. *sigh*.

KDavison, the issue we were experiencing was tied to the Aeroscout exciters and the tags not beaconing correctly. I don't have the exact details as our Aeroscout environment is managed by someone else, but essentially when they were testing the new deployment, at times the location engine wouldn't register that they had entered a patient room like it should (we use Stanley Critical Alert that ties into Aeroscout). Apparently this is fixed in the MR2 code but breaks voip - I ended up configuring a spare 5508 with the MR2 code and moved only those floors that need this feature over to it while leaving the rest of the hospital on my 5520 running 8.3.112.0.
I'm somewhat glad to hear I'm not the only one that had the issues. I will say that the 8.3.114.74 code doesn't have the one-way audio problem as "bad" as .57, but it's still there.
BMHanson - thank you for the info, I may need to investigate and see if I can get my hands on 8.3.112.7 as the info for CSCvd69992 definitely sounds like what I was experiencing on the 3802s.
Thank you everyone for the input, it's greatly appreciated!

From the sounds of it, you might referring to bug CSCvd69992 which is actually fixed in 8.3.121.0, but then you still have the same problem I have (CSCvf29221) with VoWLAN with 8.3.121.x code. The release notes that TAC provided me yesterday on 8.3.112.7 indicates that CSCvd69992 is fixed on 8.3.112.1 Special Build so therefore it's also included in 8.3.112.7 Special Build. We haven't even been 24 hours yet on 8.3.112.7, but we no longer are having 7925/8821 one-way audio and de-registering issues that we had on 8.3.121.x. We also have around 146 2800 series APs and haven't experienced RFID/AeroScout issues either on the special build. Just from my experience the last few weeks, if you have 7925/8821 + 2800/3800 AP + AeroScout RFID in your environment, 8.3.112.7 is what seems to work for us so far.

My SR is 682572370 with associated bug CSCvf29221. I'm not sure why TAC wouldn't provide you with a 8.3.112.x train...it says right in the CSCve20123 bug details that "This bug does not affect 8.2, 8.3.112.0 or 8.4 - only 8.3.121.0."
From my experiences with our VoWLAN problems, I would not recommend any 8.3.121.x release for anyone with 7925s/8821s. The bug we discovered in 8.3.121.x CSCvf29221 is a new bug in which TAC can easily replicate in their lab (the WLC is not forwarding TCP ACK from CUCM). The bug you mentioned CSCve20123 is actually fixed in 8.3.121.4. That bug never affected us anyways as we do not use CAC/AVC, but TAC had us upgrade to it only to find out we still had VoWLAN problems w/ one-way audio and phones not registering, hence the new bug was logged.
Like kdavison007 said, I can't believe this is a MR2 release. I'm thinking Cisco might have to make 8.3.121.x a deferred release and hope they fix all of these VoWLAN problems with 8.3MR3. In the meantime, I strongly recommend going back to 8.3.112.7 until a new 8.3 MR is out.

Thanks for the SR number.
I've asked TAC to provide me with the latest escalation release for 8.3.112.X and he's looking for it.
Going to see what he will provide on Monday.
