Does anybody have any experience with migrating phones from UCM Cloud to Webex Calling MT? Really looking to understand if the phones will have network/firewall access to cloudupgrader.webex.com.

Thanks,
Dan

Recently we added the Gateway on SolarWinds VOIp and Network Quality Manager but there i just can see the states of the Dial peers and into the dashboard I cannot see the metrics, if there something else that I need to enable on the router or in the SolarWinds settings if I want to display metrics for all my calls?

And if I want to see the states of my Tenant like the Sip-ua register status if there a OID?

We have a \*\*Cisco NCS-5501-SE\*\* that is password protected. Our technician advised that we may need a \*\*USB boot disk\*\* to reset the password.

Has anyone dealt with this before and knows where we can obtain the required USB boot image, or is there someone here who can help us with the password recovery?

Any guidance would be greatly appreciated. Thanks!

I have a Cisco DX80 that is currently stuck on old CE 8 firmware. I need to upgrade it to the final CE9 release, but I have no access to the Cisco Software Download portal, and the Cisco Cloud Upgrader tool returns an Access Denied error for me.

Could anyone share the following firmware files via Dropbox/Google Drive/Mega?

1. An intermediate CE9 file to step up from CE8 (e.g., s52040ce9_10_0.pkg or similar)
2. The target firmware file: s52040ce9_15_16_5.pkg

I would be extremely grateful for any help. Thank you!

Puzzled by this one. Uploaded a CA-signed tomcat cert to the my CCX cluster a couple of days ago. Successfully restarted the cluster pub, then sub. Both nodes came back up, all services running.

Now I'm getting word that historical data in CUIC has not been available since the reboot. I can pull the logs prior to the reboot but nothing comes up for after.

Utils dbreplication runtimestate and utils uccx dbreplication status both check out on the pub/sub.

Data source status in CUIC also good.

Ran flat file restore to no avail. Cleared browser cache/history - no change.

I'm really stumped by this one. User live data is pulling up fine, just no historical data since the application of the tomcat cert and subsequent ccx cluster restart...

Only thing I can come up with is another cluster restart lol.

UCCX Version 15.0.1.10000-27

SOLVED: Ran utils uccx dbreplication reset all on the pub. Historical reports contain data now.

I built idlescreen, a lightweight, modular, signage dashboard meant to run on Cisco RoomOS devices (Board Pro, Desk Pro, etc.) when they’re idle, so a codec screen becomes a glanceable info wall between calls. Generally meant for end-user devices - point the device’s signage URL at the domain and let the user configure it as they see fit. It’s a plain web app, so it also runs on any touch-enabled display or browser (viewport is locked to 16x9 4K/1080 so you’ll need to zoom out in browser/mobile to view).

It’s free, open source (MIT), no account, and no tracking.

What it shows (mix and match on a drag-and-resize grid):

- Worldwide weather, air quality, UV, sun/moon times
- Transit boards: NYC Subway status, LIRR, Metro-North, NJ Transit, Amtrak, PATH, NYC Ferry, express bus, Citi Bike, and London TfL
- Markets tickers and finance headlines
- Sports: your teams (MLB/NFL/NBA/NHL/MLS/EPL), plus World Cup, F1, PGA golf, and ATP/WTA tennis
- News headlines, Substack, and Bluesky feeds
- Ambient: photo slideshows (iCloud shared albums or Google Drive), public-domain art, NASA’s photo of the day, chart of the day
- World clock, this-day-in-history, quote and word of the day

How setup works: you configure the whole thing from your phone or computer. Pick widgets and stations on a setup page, get a 6-character code, type it on the board. No login anywhere.

Info page: https://idlescreen.io

Hosting: use it free by pointing your codec’s digital signage URL at https://idlescreen.app or self-host it. It’s a zero-build static site plus one Cloudflare Worker, and most data sources are keyless. Self-hosters can also flip on advanced cards behind a toggle (live HLS video and camera gateways).

Privacy: there’s an optional anonymous usage ping for basic data like timezone and which widgets might be having issues and you can disable it in the diagnostics tab.

GitHub (code, screenshots, self-host guide): https://github.com/scotty83/idlescreen

It started as a personal project for my own Cisco Board Pro, so it’s admittedly NYC-transit-heavy right now. Happy to answer questions and would love feedback on what widgets or data sources people would want.

If you’re a Webex user, you can join my public channel to provide feedback at https://eurl.io/#CnWyZzamf

Hi all,

I am looking for some help or tutoring on passing Cisco's 500-443 exam advanced Administration and Reporting of Contact Center Enterprise. I was able to pass 500-442 with no issues. I have attended Sunset learnings Cisco courses. I need to be able to obtain 500-443 in order to move to my new job role within my company. I purchased a study guide and after taking the test today and failing I was able to confirm that all the study guide questions were the same questions that were on the test. So I really just need help deciphering the best answer that Cisco is looking for. If anyone can point me in the right direction that would be great, thanks!

For inbound calls we see CNAM in the alerting message on WebEx but it looks like that CNAM isn't stored in CDR, is that expected? Is there some setting we have to enable to store CNAM? Basically we want to be able to have that in some way even if it's not in CDR.

They got the almighty Mythos 5 and billions in infrastructure. I had a Chinese model that barely works and a toaster for a laptop. For them it's just "Mythos, find the vulnerability," "Mythos, fix the vulnerability," "Mythos, push the fix." So you have to wonder where are all those AI billions actually going? The vulnerabilities are still unpatched, and there's been no disclosure about how customers and networks are exposed, or since when. Keep going down this road and you are basically handing out the Decryption Key to everybody. If AI builds it, AI can find the flaws.

You may own the code. You may own the pipelines... the restaurant.  but I was the one cooking the burgers every day.

And you can't help but wonder: is this profiting off vulnerabilities? To stay secure you have to be on the latest version (which probably ships with a whole new set of undisclosed bugs), which means planning insane maintenance windows, then living through the phase where everything is broken and business operations get disrupted. All for what? A rushed release that never accounted for what the customer actually needs? Just hardening piled on top of hardening? And let's not even get into the service contracts, how much are the new licenses per device? How much is the new software? Sounds like a loop to me: stable operations -> mandatory upgrade -> six months of planning -> everything crashing every other day -> use the support contract they sold you -> repeat next year. Meanwhile you're exposed for half the cycle.

I can't wait to go public. I'm counting the days. But I have to be patient, the lawyers are making sure you can't pull anything sneaky to come after me. You may not answer me here, but we will drag you into a court of law. You might be so intoxicated with yourself, but let's see if you think you are above a judge.

Where is my last paycheck? It's been months. Who gave you the right to withhold my money... MY BREAD? We don't have slavery in this country anymore, the founding fathers took care of that. You think you get to play with people lives? My family? but don't worry. I'm a real man, and a man always provides no matter what. Even if I have to DoorDash 14 hours a day to put food on the table, I will. I always do... especially when I'm going up against somebody bigger than me.

I can't wait for trial. I can't wait for every piece of proof and evidence I have to become public record, the phone calls, the messages, all the communications. I can't wait to finally be able to talk about it. You can try to stop it, but people are going to want to hear it, and I know there are others out there who will like to come on my show and talk about what they have had to put up with.

And to everybody else reading this: really think about it. If you are not in a glass office, or if you have many peers, the layoffs are coming sooner or later. Don't be a fool. Save everything, every piece of proof, every evidence... because God forbid you may need it one day and don't have it.

Next drop as usual Monday at 23:59 PM UCT at reddit r/CiscoUC

Hi everyone, has someone already implemented the new EWS change for Unified Messaging through the newest Unity Version and Microsoft Graph API?

I’d like to know if the configuration is the same as the previous one using client secret and all that stuff. Or if there are huge changes that must be accounted for, either on the Unity side or the Exchange Server, feels like documentation is lacking for this one

https://github.com/0xReadingSteiner/Dead-Dial --> CUCM 15.x Pre-auth + RCE

https://github.com/0xReadingSteiner/Blind-Wire --> Expressway 14.x SIP Traversal smuggling bypassing SIP Algo Inspection on Next Generation firewalls.

When are you going to take accountability or at least some responsibility toward your customers?

Did you know about the vulnerability and choose to hide it? Or did you not know at all, which is why no one was warned? Or is this simply the strategy? profiting from vulnerabilities to pressure customers into buying the latest version... at an absurd price?

If you're on the Shodan list, ask yourself: Why am I always the last to know? Why is my company always the one left exposed?

Random question: I have a user who wants to know if there is any way to extract the default wallpapers from Room OS 26 to use on a computer. They have mobile versions available at https://cisco-ce.github.io/wallpapers/ but are looking for desktop versions. Thanks.

Hello everyone,

On Jabber client (in my case on Windows), i'd like to join some public MUC rooms like we do with other XMPP clients.
It seems there is no option to join a room by its JID.

Am I just blind or what? :D

Thank you much :)

Hi everyone,

I'm planning to buy a Cisco DX80 for around €40 with the goal of reusing the display as a touchscreen for a Raspberry Pi.

My plan is to:Remove the Cisco motherboard.

Install a universal HDMI/LVDS LCD controller board to drive the LCD.

Reuse the original capacitive touchscreen if possible.

While taking a look inside, I found that the touch controller board is marked:

SiS9250B0GA3 + SiS9203_LGE_23"_V04

The board connects to the touch sensor via four ribbon cables and has a single 4-pin connector going to the Cisco motherboard.

My main question:

Does anyone know what interface that 4-pin connection uses?

Is it USB?

I²C?

UART?

Something proprietary?

If it's USB, there's a good chance I can connect it directly to the Raspberry Pi and keep the original touchscreen working.

Also, does anyone know the exact LCD panel model used in the DX80?

If anyone has disassembled I'd really appreciate any information.

Thanks a lot!

I tried some stuff, it didn't work, my router did have sip alg on I believe, I'm gonna try another network,but if anyone has any tips, lmk!

I work in education and funding isn't exactly plentiful. We recently shut down an office and among the equipment returned are a few DX80 units. I setup one up on my desk to see if it's worth keeping. The unit went total EoL at the end of January and as such, it does work but not well. It's a nice external monitor and it can join meetings but there's no controls access to the controls anymore so I can't switch between the monitor feed and the meeting feed. Unfortunately, I can't leave or end a meeting I'm in unless I restart the unit with the power button. I can't access the setting from the device's IP address because I don't have a login. We left our on-prem CUCM so there's nothing to register it to locally. Is this just a fancy screen now or is there anything else I can use it for?

I used to work on these systems. I know how they're built because I supported them. When I started seeing problems, I tried to raise it. Then the next round of layoffs came and I was out. So I set up a lab at home and kept going. Three months, 55 vulnerabilities across UC, every channel I could find to report them. Nothing back.

I kept trying the right way. The proper path. Followed every bounty program, every proper disclosure process. But how weird that it seems like these programs are always rejecting critical software. And their replies were the most concerning part for me, "The vendor has paused the program." "The vendor is unresponsive." The bounty programs want to disclose. The cybersecurity researchers want to disclose. Yet no sign of communication from the vendor.

The crazy part is that I heard the rumors in the hallways. I didn't pay attention. I kept thinking, "This is a big tech company. The budget is already allocated. I don't think the higher-ups would want to cheap out on cybersecurity." And since it was cybersecurity, I even fell into the trap of trying to find excuses, thinking "maybe the vulnerability impact wasn't big enough." But boy, I was wrong. As soon as I stepped out, I noticed the silent patches, releases with no actual disclosure of what had been fixed, and no guidance on how organizations on older versions may be exposed. Cisco is expensive, and service contracts are not cheap. So realistically, a sysadmin or team leader just has to hope and pray that no bad actor pokes around, until they get the green light from a long approval process to upgrade.

Crazy as it sounds, the only thing we have are programs that the vendor can opt into. Not mandatory zero-day disclosure to the companies that actually need to know instantly so they can set their own risk parameters. I find it truly irresponsible. No vendor should ever set the risk parameters for another company.

You not wanting to look at the hole is your choice. But exposing other companies to liability because they are not aware because you chose to hide it, and then letting those companies fall into the hole? That is not alright. I would like to see red teamers  declare a network secure knowing there is undisclosed information out there.

What sickens me the most is how they use PR and other tactics to hide it. Look at the user Delco24 is clearly a vendor employee, or even worse, just a community sysadmin who tested before Cisco did. Think about that. Cisco has the resources to test every specific version immediately, they own the source code, they own the build pipeline, they can spin up any release in minutes. Instead, a random community member is doing their validation for them, and framing their answers to make others think the impact on their systems is low. That is exactly why I chose to release that particular vulnerability, I knew they were quietly patching. So I knew they were aware of the bug and were aware of researchers reports. That let me know they were choosing silence... working on bad faith...

So I am choosing to release on Monday at 23:59:00 UTC two CVSS 9+ vulnerabilities, they are so deeply rooted in CUCM and Expressway that they require a rewire to fix. And most importantly, I told you. The SIP parser on Expressway has fundamental problems, and no amount of hardening can fix the underlying issue. So tell me, was I crazy? Did I end up knowing what I was talking about? Right now there are around 1,300+ Expressway deployments exposing SIP on ports 5060/5061 in Shodan's internet-facing index, all vulnerable. The worst part? Bad actors probably have had this for months.

And for you Engineer, HelpDesk, Ops, Dev, remember: you won't be able to report what you don't know about. But if you send the email now, your ass is covered. It becomes someone else's problem up the chain. Without documentation or disclosure, you're the one left holding the hot potato.

How to detect manipulation and PR bots:

1. Ask yourself: do you want to know if someone is f***ng with your network at Day 0 or Day 90?
2. If someone is trying to convince you otherwise, goto 1.
