Re: Polycom Trio 8800 with Skype for business not working

Hello @sivaramakrishna ,


Welcome to the Poly Community.

Please ensure you always check the FAQ's and/or utilize the community search before posting any new topics or follow up posts.


Jan 17, 2017 Question: How can I troubleshoot simple Skype for Business, Office365 or Teams issues?

Resolution: Have a look => here <=


As this stops you from using the Trio and if the above FAQ does not help you to troubleshoot I suggest you get this into support. Other community volunteers may be able to advise you further.


In order to raise a support ticket, you need to work with your Poly reseller as they may need to do this for you.

End Customers are usually unable to open a ticket directly with Poly support. Available End User Poly services offerings are detailed here

Our records show INGRAM MICRO sold this unit back in 11/05/2017 so I assume this is not a day 1 issue.

As the unit is no longer within the 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

Steffen Baier

When you say "tried to log in through web", do you mean you're trying to use the Web Sign In option from the touchscreen of the device? Or are you logging in to the web interface of the device and trying to sign in from there?


Also, are you signing in to Skype for Business Online, or on premises?

Are you using interal PKI (certificates) on SkypeForBusiness? (assuming you're running onprem)

If so, make sure the root certs of your PKI are known on the TRIO. You can upload them from the web-console, or import them in a configuration file.
