Upgrading a Trio8800 from version 5.5.3.3517 to 5.7.1.4133 prevents the Trio from authenticating to Skype For Business. Downgrading the Trio back to 5.53.3517 allows the Trio to authenticate again. I Have attempted staged upgrades to the versions in between, but does not fix the problem.
Hello @dpegler,
welcome back to the Polycom community.
Some or a couple of your old post(s) => here <= are still open / pending as you have not marked these as "Accept as a solution" or at least provided 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 utilise the community more efficiently. Please do not simply mark them and provide some usable feedback.
For your new question both the Read Me First and the FAQ explain what kind of minimum basic Information we do need to reply with anything useful.
In addition there are troubleshooting sections within the FAQ.
If you are unable to follow these please open a support ticket.
In order to raise a support ticket you need to work with your Polycom reseller as they need to do this for you.
End Customers are unable to open a ticket directly with Polycom support.
If this is some sort of an Internet discounter please post either your phone's MAC address or your Polycom devices serial so we can look up who would be able to support you. This may not be who you purchased the Polycom device from.
If the unit is no longer within warranty please be prepared to Pay Per Incident / PPI. This is all outlined in detail here
Please ensure to provide some feedback if this reply has helped you so other users can profit from your experience.
Best Regards
