Yealink MP56 Microsoft Teams Certified handsets do not sync Outlook contacts

We've deployed a number of Yealink MP56 headsets and cannot get Outlook contacts to sync.  We've attempted just about everything to force a sync, but it appears as though the handsets only display co...

ChapmanBryan  It's November, we're still seeing latency issues. Just deployed 122.15.0.60 yesterday and praying it improves our situation across 60 users. We've contacted Yealink and they blame MSFT, but other manufacturers don't seem to have the same issues. We're working on automation to reboot nightly to help mitigate the slowness and instability that seem to increase as runtimes increase.

 

The change management for users going to new phones/Teams is tough enough when everything is working perfectly. It's much worse and harder when the phones don't do the basics well: pickup when users lift the handset fails sporadically, audio is delayed on calls, sidecars go blank, just to name a few of the pain points with the MP56 device.

 

We're evaluating the warrantee of these devices which aren't performing as expected and may have to return them all and re-deploy another device, which will impact us as an IT team as well as every one of our users.

    Hi Roger Navarro If you find that 122.15.0.60 doesnt improve it at all, we've recently started running 122.15.1.27 which is supposedly the most up to date firmware. Whilst we still have the same occasional issues with pickup on handset lift/no dial-tone on handset lift, it does seem to be slightly better overall. 

     

    If you need the ROM file (we were only given it after our separate support company chased Yealink for ages) i've uploaded it to "WeTransfer"  since the file size is too large to attach here or send via email (even zipped the file is 700mb, what do they put in there!?)

      Hi Mickkey, we worked with Yealink to get the firmware 122.15.1.27 and had it running only on few phones since it a BETA release. We were assuming that the November 3rd release of 122.15.0.60 from 122.15.0.44 would fix the issues as stated in the release notes:
      1. Optimized audio latency.
      2. Optimized UI reflection latency.
      3. Optimized screen saver timeout
      4. Fixed an issue that device is offline from TAC.

      Now we have 11 phones offline in TAC showing as software update failed, rebooting, signing in/out does not fix. The phones do show online in the Yealink Management Cloud Service with the new firmware (122.15.0.60) and you can redeploy it as it fails because it's the same version. I suppose I will update offline phones with the firmware to 122.15.1.27 and see what happens.

      Thanks all for posting!

        Hi scottphayre , you're right, in my TAC it's showing a whole host of "non-urgent health status'" due to the firmware wanting to update, despite being as up to date as it can be, which I hadn't thought to include in my above post. As it doesnt effect the users (and I log onto the IP UI of each phone individually if I need to (small team)) i'm happy to have the TAC look awful whilst the users benefit from slightly better performance.

        If you remember to, come back here and update us with how it goes!

        Cheers,

        Mike
