Telephony-0010 and Telephony-0011 Events recently started

  • 1.  Telephony-0010 and Telephony-0011 Events recently started

    Posted 09-29-2025 10:37

    Good morning all,

    Curious if anyone else has ran into this issue.

    We are a FedRAMP customer and starting last week (09/25/25 to be exact) our Edges (vendor managed) were updated to version 1.0.0.26833 after midnight on 09/25. Starting at around 6:20AM EST, we began receiving Telephony-0010 and Telephony-0011 events for the very first time (we've been on the platform for around 18 months and cannot recall receiving these two specific events until 09/25). We also have a trigger setup to email us when operational events occur. We cannot find an email for previous 6 months of these events occurring.

    We can recreate the 0011 event by running webRTC diagnostics and this occurs whether we're on our corporate network or using a personal machine from our home network. Several of our folks have recreated this. We highly suspect the Edge update to 1.0.0.26833 or something w last weeks platform release has changed something which is now leading to us seeing / receiving these two specific events. Has anyone here ran into the same issue or something similar? 

    You can also spot check these from the Operational Console. Seems odd to us that multiple users can recreate off or on network and these first began happening last week. Seems logical to think something changed somewhere.

    We have an open ticket w support, thought we'd check here as well.

    Telephony-0011 is a DTLS Peer Disconnect event 

    Telephony-0010 is a WebRTC ICE Idle Detected

    Thanks as always!

    Hi Shane,

    That's an interesting one.  Hopefully others in the community can comment if they are seeing similar.  If not, please let us know of any resolution provided by Genesys Product Support as it may help others in the future.

    Hi Shane,

    We have an implementation for a customer that was using the trigger ...user.end to check the conversation.details api for the sip response 480 (IceIdle) on the interact session. We would then be able to perform our own logging to datatable in order to potentially respond back to the customer in a post flow, and to check on agent behavior/network stability, as this event was also signaled if an agent performed a browser refresh while on a call (call avoidance).

    This all changed on 26th August for us with the same edge update. (Case #0003863445), and the same  observations as you had above for the operational log. Genesys confirmed these changes.

    Unfortunately the event model also changed to report the 480 sip response. The customer segment now shows the 480 sip response in the interact session, which is now immediately disconnected also (previously the customer was still active). The disconnectType for the trigger changed from 'ENDPOINT' to 'ERROR' on the agent side, with an iceIdle WebRtc error code.

    hope that helps,

    Hi Kevin / all,

    Really appreciate the information and good to know we aren't totally alone in this. We felt pretty strongly that the Edge update led to these new events / errors being reported. We're now getting them hundreds per day and previously we were getting zero of these specific errors. Kind of crazy that we can also recreate at least one of the "errors" on demand by simply running WebRTC phone diagnostics.

    Kevin, did you get any indication that Genesys would address this or correct this issue?

    Seems like that Edge version introduced or significantly changed how the Edge processes these events. To your point, we also have a trigger and thus are getting email notifications each time these events are generated and we also noticed the disconnect type being ERROR now vs. ENDPOINT for some of them. Just curious if you got a sense this is something Genesys can/will address? 

    I'll reach back out to support via our open ticket and ask for additional information and if there are next steps as well. I'll update here if I learn anything more/new.

    Thanks again all!

    Hi Shane,

    Case with Genesys just provided the confirmation that the operational console events and the session model changes were intended. For me it seems that all of the operational console events relate correctly to the agent disconnects that we were seeing before, mainly due to home working issues / network drops etc.. in similar numbers that I previously saw, spread over the 3 console events, 10,11 & 12. 

    personally I see this as a positive change, just would have been nice to know it was coming!

    Shane,

    Do you receive any errors when running WebRTC phone diagnostics, or does it run successfully and you get a TELEPHONY-0011 event?

    Thanks,

    Hi Chad,

    Just tested this on our VPN and off the VPN.

    Both scenarios seemed to behave the same. We do get an error as shown in screenshot below, but if we wait it out for 15-20 seconds, we eventually get Test Results and they are positive. We first thought this was something to do w our VPN (Zscaler), but this behavior also occurs off network from our home network. We've had several individuals test this from their home network w same results. We do have supposedly ALL RTP traffic bypassing Zscaler when on network, but again this seems to occur even when not on the VPN.

    This also generates the Telephony-0011 event when this occurs.

    Are you able to replicate this at all?

    We use ZScaler as well and have RTP traffic bypassing it.

    I've tried running Diagnostics several times on and off VPN, but I could only get that error message you are getting immediately after disconnecting from the VPN.  If you run the Standalone WebRTC Diagnostics app, do you get that error as well?

    Just tested using the Troubleshooter URL and received same behavior (both off and on VPN, from different machines as well)

    Call Quality attempts to check, then goes to "Checking -> Never Ran", but I can see it dialing *86 in background. Then after waiting 10-15 seconds, it then shows "Excellent" for Call Quality. I tried this multiple times in a row and each time had same behavior.

    You can see the 'Never Ran' below, but if we wait 10-20 seconds, that changes to Excellent as shown in screenshot 2.

    Now Call Quality is "Excellent" after waiting 10-20 seconds while *86 and diagnostics completes

    Hello, 


    Same here, we've been experiencing these errors throughout the day for several weeks now.
    In our case, we are not a FedRAMP customer, but this issue is also bothering us quite a bit.

    Hello,

    we have an org on Tokyo with the same edge software version of 1.0.0.26833 and we notice an increase of reported issue as well where agent experiencing Call error: WebRTC endpoint disconnect, reason-iceIdleDetection, there are also reported error which is: Failed to rejoin call leg.

    We are a FedRAMP org and have also seen telephony 0010, 0011, and 0012 errors for the first time starting on 9/25/25.

    Has anyone received any more information about this? 

    I'd like to know before we have to open a support case to find out if this is simply a matter of something that has always been occurring but wasn't reported in the ops console versus something new that is happening.

    We also seem to have increased reports of WebRTC endpoint disconnect, reason-iceIdleDetection and Failed to rejoin call leg.

    Similar to @Judy Kerbel, unsure whether this behaviour always occurred but now is displayed slightly differently in Genesys, therefor have not raised a case with Genesys (yet).

    High proportion of our staff work from home.

    Our Org is in EU2 running on Edge version 1.0.0.26833.

    We've also gotten report on this issue happening lately while agents have the call on hold.

    Haven't gotten anywhere with support who basically just says it's a customer network issue, but seems there's a new Edge firmware release that should be deployed this week. Hoping that will solve the issue.

    Looking at some client traces it seems that the STUN request gets "Destination unreachable" after a while from the Media server but need to find out if it is the same at the customer firewall.

    Yes, I reported an increase in these 2 events on 10th September. Genesys investigated and have currently determined the issue is on our side, so the incident is with our network team for investigation.

    Hi Ernest,

    A brief anonymized summary of what was observed..

    On receiving an inbound call, media negotiation was set up between:
     
    Remote endpoint (our agent): Public IP A
    Media server: IP B
     
    However, instead of receiving media from the expected remote IP (IP A), they observed:
     
    Connectivity checks (STUN packets) and RTP packets from an IP address (IP C), which was not part of the ICE negotiation.
     
    This kept happening for approximately 10 seconds, during which:
     
    No RTP packets or connectivity check responses were received from the expected remote IP (IP A).
    RTP packets were received from the unexpected IP (IP C) and discarded.

    Thanks for sharing!

    Did you find this on all interactions or did it only occur on a certain proportion? 

    Was there any particular duration these interaction would eventually "Error" and disconnect?

    "This kept happening for approximately 10 seconds..."

    Would i be right in staying you saw this in the PCAPs, with multiple Requests / Status every 10 seconds?

    Posted 10-03-2025 10:37

    10 seconds matches a recently-discovered issue when Group Policy gets applied to a Windows machine (I think mainly Windows 11) that results in sending sending an LLDP Shutdown message:

    "...an LLDP packet which states 'Shutdown LLDP'. This packet causes the NIC on the machine to essentially be reset, and since Genesys Cloud does not currently have any ability to reestablish ICE connectivity after it has been lost the call will simply disconnect."

    There is a fix currently in Limited Availability status which will allow for "...graceful media stream recovery for WebRTC calls"

    So, when you communicate with Support you might ask about the steps you can take in Group Policy to avoid that particular issue.

    To test the effect,

    1. On an affected user/machine, perform an outbound WebRTC call from Genesys Cloud.

    2. Open cmd.exe as administrator on the machine

    3. Run the command 'gpupdate /force'

    If the client is affected by this issue, you will see the call disconnect about ten seconds later. If you do not see the call disconnect after running the command above, you likely have another bit of software which is triggering the LLDP shutdown.

    Hello George,

    Thank you for the information. I believe the following points remain unclear:

    • Was there an Edge update that introduced a change in how the IceIdle error is reported?

    • Prior to this change, did the IceIdle error result in call disconnects/dropped calls, or was it only visible in the logs?

    Thank you for clarifying.

    Hi, All

    We reported this kind of issues, and this is the response of Genesys Support.

    Since Edge release: 1.0.0.26833, Organizations will now be able to see the WebRTC disconnect errors logged in the Console. Events such as the Telephony-0010 and 0011.

    • This logging was previously not being included or displayed in the Console due to the manner in which Genesys handled WebRTC station sessions during interactions. Since the session handling has been updated with the modern WebRTC feature, this now allows the details for the WebRTC disconnect's Analytics data to be logged and available to you.
    • Please keep in mind that the presenting of the errors now do not mean that you are now experiencing "new" issues/errors, but this is more to provide more details regarding what occurred and identifying the disconnect reason.
    • Previously you would need to raise these disconnect issue with Support in order for us to identify what caused the disconnect. Now as an Admin in the Organization, you will have more details with those Telephony Events.

    I hope this will be useful :)

    BR

    Hello Adrian,

    Thank you for the update. From your message, Support confirmed that the recent change was only related to logging and reporting in the latest Edge release, and that this update - and the visibility of this error - does not indicate new issues for agents.

    However, I'm wondering why we've seen an increase in client reports of dropped calls since that update. While the error may not have been visible to agents previously, any dropped calls that occurred have always been reported by the client."

    Hi all,

    we've done an analysis of these messages and we could see an increase in those messages. So an increased number of reports is also based on an increased number of this happening. It might be related to some new Win11 policies, because there is also some patching of Win11 running, but it's hard to get to the root cause.

    @Shane Jenkins, @Ninette Elashry, or anyone else, are your employees using the Genesys Desktop Application?  We recently found a bug in the newer releases of the Desktop App that periodically prevent screen recording, so we had to roll back to ver.2.43.829 while the issue is being resolved.  I don't think the Desktop app would have an impact on this particular issue of dropped calls, but we aren't ruling it out.

    Hi Chad,

    Appreciate the info on the Desktop Application.

    I did some testing yesterday / today from both the Desktop App and Chrome browser. Both seemed to exhibit the same issue/error when running Diagnotics. We do understand that in some (maybe even most cases) the Telephony Events 0011 at least are benign, but we cannot determine which are 0011 events are benign vs which are real issues.  As mentioned before I've tested both off/on our VPN and from a company provided laptop as well as a personal laptop on my home network. I can get Diagnostics to run without error maybe 1 out of 5 times. The other 4 times, I get an error in Diagnostics as well as a Telephony 0011 event thrown. This behavior for our Org appears to have started around mid September and has continued. I've asked support if they can help determine why Diagnostics is throwing an error and 0011 event (even when Diagnostics is successful). Really need the behavior corrected so that we can focus on any 0011 events that are truly an issue.

    Thanks,

    Shane

    Thank you.  When I dug into the TELEPHONY-0011 errors, they seem benign for us too.  The TELEPHONY-0010 errors on the other hand are dropping calls.  We have engaged our Network, Desktop Engineering, and InfoSec teams to see what, if anything, could be occurring in our environment.  Since you, Ninette, and others have also reported an increase in dropped calls, it makes me think this isn't necessarily tied to our environment, unless it's tied to a common underlying OS or hardware driver issue.

     

    I was only able to recreate the error you are receiving with the Diagnostics tool once.  I assume you've confirmed with your firewall/Zscaler teams that all required CIDR block and port ranges are open?

    Yep, the RTP and audio ports should all be allowed and actually totally bypassing Zscaler for our FedRAMP CIDR range. 

    Strangely enough these same errors occur for us even off our network (no Zscaler/VPN involved at all). I can replicate the same 0011 errors from home using a personal Windows or Mac device that isn't on or managed by our corp network. Several of my colleagues have replicated this from home as well, so it doesn't appear to be isolated to Zscaler/VPN.

    Hi,

    Our company (org) also suffers from begin september this 0011/0010 ICE-IDLE errors and yes, we know these errors weren't visible before in diagnostics, but we do have hundreds of agents and logging and we can tell by them and the logging that there is a significant increase of suddenly disconnected calls in our org too. We also have engaged Network team and ZScaler is bypassed and cidr and portranges are checked.
    So don't feel alone! We would love to have this issue solved since it is so hard to find a root cause.   It happens in every type of conversation, no matter if your working from home, office, wifi, wired, Azure virtual desktop, thick client app, Chrome, Edge.

    We are using Desktop and still experiencing the issue no matter what version of the desktop we apply.  We just pushed out 2.46.855 to test user group and had dropped calls this morning. I was hearing that this was an Edge update from August, that was the last time our performance was stable, and calls were not dropping so frequently.  Does anyone have a workaround yet? I continue to send captures to our support ticket but no recommendations yet.

    Hello Wendy,

    I have done some digging internally and have found some info from a dev ticket. From what I have gathered, we did not make any changes to how Genesys Cloud functionally works. There was a change to the criteria of what would trigger a Telephony-XXXX alert that would now more accurately report calls that experienced those issues. The agents that are showing up in the reports having Telephony-XXXX errors were having issues before the change was implemented.

    I have only been able to find 2-3 cases that were opened with Product Support so if you have a case opened with our Support team, please share the case number so that I can monitor the issue internally as well.

    Hi Jason, 

    Thank you for the information. We understand that this is the expected behavior and aligns with what Support mentioned previously. What we are trying to determine, however, is why we are seeing an increase in reported dropped calls, not just why the error itself appears.

    When we speak with agents and review the call history, the volume of dropped calls used to be significantly lower. Support is indicating that the issue is related to network instability, but all clients have confirmed that no network changes were made.

    Hi Jason,

    I feel compelled to respond to your response to Wendy.  We have been advised of the more accurate code, but are having difficulty getting anyone to recognize that we actually are seeing an increase in calls dropping.  It's inconvenient that the increase in disconnects appeared simultaneously.  There were other changes made to the edges that week.  It would be great if someone could look further into this as we are not seeing, as suggested, any issues or changes in our network or PCs that would cause a 10 second loss of communication and all versions of the desktop app are impacted.

    There's also this forum discussion Desktop App v2.44.848.0 Crashing During Calls – Anyone Else Seeing This? | Genesys Cloud - Main - this also results in dropped calls and is reported as a telephony event. The timing of this matches up with the timing of the increase in telephony events across the board. We are still experiencing ongoing telephony events even on the current desktop app version.

    Hello,

    Just wanted to add seeing the same thing on our end. We are US-EAST. Almost completely work at home, VPN with split tunneling, WebRTC, Web app (Chrome) and Desktop app. Haven't been able to find a pattern yet and I have seen call examples of agents both using the web and desktop app. I do see in the operational console it happening and not being reported to us, but the first ever report of this was at the beginning of October. Console shows it's happened over 150 times so far this month. Still into things, but just wanted to report.

    We have also experienced ongoing issues with Telephony-0010 over the last month or so. These occur for agents both in office and working from home. A case was logged with Genesys who advised:

    This indicates a network-level issue. Specifically, the Edge component stopped receiving RTP packets from the client. As a result, it initiated an outgoing ICE Connection Management check but did not receive a response. Consequently, the Edge terminated the WebRTC connection.

    The idle detection mechanism is designed to prevent users from remaining connected to non-functional WebRTC sessions. In this case, RTP traffic from the agent's PC failed to reach Genesys infrastructure. Potential causes include network latency, firewall restrictions, or other connectivity disruptions.

    The ICE connectivity check has a 2-second timeout. If no response is received within that window, the connection is considered idle and is disconnected. We recommend conducting an internal investigation involving your network, firewall, and - if applicable - security or VPN teams to identify what may be blocking or delaying RTP traffic. The disconnection occurs because the expected traffic does not arrive in time, triggering the timeout

    We've seen no sign of improvement; today we've had 18 telephony errors in 8 hours alone. To assert that it's occurring due to network issues across such a broad range of customers seems disingenuous ...

    Matthew,

    Thank you for your input.  We received a similar response from support on our case regarding this issue.  One thing seems different.  We were told the timeout is 10 seconds, not 2 seconds.  We can see the 10-seconds of silence in our call recording waveforms.  There is approximately 10 seconds of silence on the agent side of the conversation before the call disconnects.  We are also getting reports of the Desktop app crashing.  We aren't sure if this is related, or not, but the crash drops the call and seems to trigger a TELEPHONY-0010 error.

     

     

    We've been getting over 90 of these TELEPHONY-0010 errors a day since Media Tier version 1.0.0.26833 was released.

    We are getting hammered today, nearly 60 calls in the last 4 hours dropped.  On most days we would see 4-10 calls and accept that as possibly carrier/customer related.  We started seeing this at the end of August and for 3 Friday's in a row, we were getting hammered with tens of dropped calls and Webrtc errors.  We did notice we had a Time Drift from our clients due to an NTP change and we have rectified that, since then, we had a relatively quiet and acceptable level of disconnects since the 2nd of October.  Thought that we had fixed it but it has come back with a vengeance today.

    Is anyone else seeing elevated rates today or have they noticed certain days are worse than others?

    We are on Edge version 1.0.0.29200 and using Microsoft Edge as our browser.

    We're seeing the same issue in our org. In the past, it was linked to hardware limitations - mainly low disk space - and once we addressed that, the ICEIdle detection problem went away for a while. Then we rolled out newer machines with way more disk space, but lately the issue has started popping up again.
    Support thinks it might be something in our environment, possibly network-related. But we haven't made any changes, and if it really is a network issue, wouldn't it be affecting all our agents? They're all on the same subnet and follow the same firewall rules, so it's odd that only some are impacted.

    We thought this had more or less gone away as we were seeing a very low number of errors each day for the past 3 weeks.  Then in the last couple of hours we have had 30+ disconnected calls with the WebRTC error.  Is anyone else still getting large numbers of these errors or has it calmed down?

    Hello everyone, 

    I just came across this topic after experiencing the same issue for a couple of days on Edge version 1.0.0.29671.

    We are seeing the same error message when our agents test their WebRTC: "WebRTC session never connected. Please try again." and the same iceIdleDetection error when calls drop.

    Has anyone found a workaround for this issue? And has Genesys provided any clear response or guidance so far?

    No, like you, we are using the app and all versions of the app are experiencing the issue.  Genesys keeps pointing back to our environment, but we are not finding anything blocking the communication.

    So we have been on calls with our supplier and a Genesys engineer and here is what we have found over the past couple of weeks.

    It looks like our Client PC's are dropping UDP traffic and causing the disconnect.  In pcaps that we have sent they were able to see an LLDPDU shutdown from the PC044.

    We then see the UDP traffic is dropped, this causes the 10 second delay before the call is dropped as there is no audio from our Agents being sent.  We can still hear the customer talking.


    What we have done, after discussing with our supplier, for some users is disabled LLDP on the network card of the PC and this seems to have alleviated the disconnects for all the users we made the change for, in the last 10 days only 1 user out of 9 has had a WebRTC disconnect.  They would usually get a small number of drops each day/week.  We are discussing with our Network and security team what issues we may have if we disable LLDP on all PC's.

    Something must have changed in the August update as we definitely didn't have this volume of calls dropping before then, and yes, Genesys have been saying it is something on our network and denying that any changes were made for this to be an issue.  We did upgrade to Win11 around the end of August so still not sure what is the root cause here.  I'll update when we disable LLDP for all users and monitor for a while.

    This is helpful!  I can tell you that we had moved to Win 11 earlier this year and we did not experience this until the media tier update with all the changes to the edges.  I think you can rule out Win 11 as a cause.

    We have noticed the same with our custoemrs to, an increase in WebRTC disconnects TELEPHONY 10,11,12's.

    Aware there is a media update this week which has notes about WebRTC updates.

    Can you confirm the details and if this to help fix the increase?

    We are experiencing the same issues.

    At the end of September, we still had several devices running Windows 10, and those users reported the same WebRTC ICE idle detection problems. So this behavior is not exclusive to Windows 11.

    One thing we still don't understand is why the NIC would send an LLDP shutdown (LLDPDU shutdown) at all. What would trigger a laptop to do that?

    During an ETL trace on one of our machines, we also observed the following error for msedge.exe:

    0xC000009A – STATUS_INSUFFICIENT_RESOURCES

    To us, this suggests that Microsoft Edge (and the Genesys Cloud Desktop app as well) may not be handling the amount or type of WebRTC traffic correctly, eventually getting stuck or unable to allocate the necessary resources.

    And honestly, isn't it strange that suddenly multiple companies across the world are experiencing the same issue around the same time? That strongly suggests this might not be a local network or endpoint configuration problem.

    I couldn't agree more.  Frankly, I feel the Genesys "support" on this issue has been severely lacking.  I believe they are asking us to resolve the symptom instead of investigating the changes they made that introduced the problem.  Everyone who supports an application knows the best way to insure you get egg on your face is to say, "it's not me."
