Trio 8800 doesn't log anymore in Skype for Business O365

Hi all,

one of our Polycom Trio 8800 has stopped to log in Skype for Business. It has been working fine till some days ago. As first thing i tried to login with the same Skype for Business online credentials of TRIO on and by this way account works fine (so I am sure that no one has resetted password and on Tenant account is still working fine).

As second step i have upgraded TRIO firmware to the last version available (5.9.0) on polycom server, then i restarted system and tried to type again login credentials but still system doesn't log in. I attach the diagnostic log for help!


Thank you

Hello @FabioBip ,

welcome back to the Poly community.

Some or a couple of your old post(s) or reply(s) to them => here <= are still open/pending as you have not marked these as "Accept as a solution" or at least provide some form of feedback or answer.

If they are in this state nobody finding them via a community search will know if an answer or advice provided was useful and has maybe helped you.

Could you therefore kindly go over them and mark or answer as appropriate?

If they are marked as "Accept as a solution" other users can find these easier and it helps them to utilize the community more efficiently. Please do not simply mark them without any type of feedback.


For your new Issue please have a look here:


Oct 7, 2011 Question: How can I setup my Phone / Provisioning / Download / Upgrade / Update / Downgrade Software?
Resolution: Please check => here <=


I can see no time is set on your Trio and loads of DNS issues


If you still have issues I can see AMSI sold this unit back in 30/12/2017 so they would be your Tier 1 support in case you need to open a ticket.

Please ensure to provide some feedback if this reply has helped you so other users can profit from your experience.

Best Regards
