Phone keep losing service

I am a RingCentral partner and have several clients that are reporting that random phones will report no service and then reconnect. There is no rhyme or reason behind this.

 

We have unassigned the desk phones and reassigned them and that has fixed the issue for some but not all. 

 

As this is happening to several of my clients thar are in different areas and different internet providers and that it is random phones and not all phones we can not find what is causing this issue.

 

All network requirements are met.

    @ANayudu  One thing that was discussed with their Tier3 network/QOS person: I asked if the Yealink is using a different protocol (UDP) vs. the Mitel using TCP and that's where the issue is stemming from? If that's the case it makes me wonder if the Mitel/RingCentral integration has been problematic from the beginning.

    The local school district Network Engineer had told me they’ve had no service issues since they migrated to RingCentral, but it was random and not very often, so they chocked it up to internet or a one-off issue.

    My gut tells me this issue has been there from the beginning and only come to the surface in the recent September firmware update where it got much worse. If I’m Mitel, I’d look at how Yealink or Poly is implementing their protocols and integration with RingCentral, then determine why they are not having these same issues as Mitel Phones.

    Thanks for the update! On my latest ticket I was still informed that it was an issue with our network and that no other customers were having this issue, even though I could recreate this on my home network. Hopefully the previous firmware resolves things until they can implement a fix. I will reference that ticket number in my response.

    @ANayudu ​@ShaunJ.90   An update, I’ve been working with several different people from Tier3 support and their executive response team. We’ve definitively ruled out any network/firewall issues as the new Yealink has  no issues, and we’ve had the “no service” issue when sending a phone home with a staff member that works remote. They are stopping all network troubleshooting and are engaging with Tier 3 product/platform with Mitel to determine if its a possible Firmware/Device bug.

    They are testing rolling us back to a prior firmware (prior to the June 2025 firmware update), we are going to do it on a single phone to test and then if all is well downgrade to the rest of our phones until a fix is implemented.

    I Implored RingCentral to stop gaslighting customers in to thinking the issue lies with their network/firewall, we’ve proven that its 100% NOT a network issue. My advice is don't accept the Tier 1 and 2 responses. I had to pushback on Tier 1, Tier 2, Tier 3 when they went to Mitel and Mitel came back with “it seems like a network/firewall issue” then i pushed back to another Tier3 until i was escalated to their Tier3 Network/QOS analyst.

    For all your tickets, have them reference our Case# 29565861, that should reflect all of time I’ve been going back and forth with RingCentral on this issue, and they’ll be able to skip the B.S.

    Appreciate the update here - and great recommendation to share your case number to associate other cases that are experiencing the same issue. 

    I will say, we aren’t in the practice of gaslighting. If you run into another situation like this, please feel free to reach out to this team and we’ll be glad to assist in escalating.
    The Community team is always glad to help.

    Another Update. We’ve been monitoring for the past few weeks and the “No Service” issue has not surfaced on the phone with the rolled back firmware NOR any other phones. I’ve confirmed with the local school district that they have not had the issue either. Seems to me RingCentral fixed/patched something on their end as the timing was too coincidental that i’m working with their Tier3 and executive response teams and as we begin to test the issue is mysteriously gone.

    Moving forward we will monitor and leave the one phone on the rolled back firmware

    Curious if any others have noticed the issue to go away past couple weeks?

    We have noticed that as well just as the Teir 3 were rolling one phone back on two of my clients as well.

    Thank you for the additional update. We haven’t seen the issue for a few weeks on our side either. We haven’t made any changes to any of our phones or our network. It does seem that something has been resolved on the RingCentral side. I spent countless hours combing through our entire network to try and find the issue as they repeatedly told me that it was an issue on our side. I was also informed multiple times that no other customers were having this issue, which is clearly not the case.

    The lack of transparency from the support I experienced has been extremely frustrating for me and our end users. It feels like no troubleshooting took place and they just immediately blamed my network. I hope that they provide an update on this issue and what steps they took to resolve it. It would be nice to see some accountability. Okay, rant over now. I’m happy that the issue has been resolved for now. 

     

    Thanks again!

    A reasonable rant, ​@ShaunJ.90!
    Please reach out to us if you aren’t getting what you need. ​@Mary-Community_Moderator or myself can help to push things along or escalate as needed. 
    Glad things are sorted for the time being!

    Has RingCentral resolved this issue or not? I now have a customer complaining of intermittent no service issues on their Mitel 6900 series phones. I also saw it happen on my 6930 phone just yesterday. Did this get fixed or not?

    The last we heard about this was 7 months ago, so I’m guessing this was resolved for the above customers, but we’re happy to look into this. 

    Have you opened any cases yet?
