Trio 8800 SIP endpoint for zoom

We are testing a Trio 8800 to be used as a basic sip endpoint for calling into zoom.  We have the Visual+ for content to the display.   UC Software version 


We are able to SIP call zoom and display the content share on the display.  Unfortunately we also have the content freeze after a period of time which requires the 8800 to hangup and reconnect to the zoom meeting.  The 8800 and Visual+ are on the same vlan and same switch so connectivity should be good.  Looking a the lgs on the visual+ I see the below.   Has anyone else seen this problem? 


We don't need this room to be a true zoom room, we just need quick content sharing and with no channel from the tv to the table for cables, having the visual+ as a remote enabler would seem like a good solution but if we can't solve the freezing will have to look elsewhere

Re: Trio 8800 SIP endpoint for zoom

Hello @ms700,


welcome to the Polycom Community.

Both the community's Must Read First and the community's FAQ reference the basic minimum information a new or follow up post should contain.

This ensures the questions having to be asked are limited and any new or follow up post contains the right amount of details to ensure any voluntary participant within the community does not spend additional time chasing basic information.

As a reminder the basic information asked for:


  • Provide the exact Software Version of your Phone
  • Provide the Phone Model
  • Provide the Call Platform (aka openSIP,Skype for Business Online, Skype for Business on Premise, Lync)
  • Additional Polycom Infrastructure (RPRM,PDMS or BToE)
  • If applicable provide a backup of the phone in question

UC Software 4.0.0 or later via the Web Interface Utilities > Phone Backup & Restore > Phone Backup > Phone Backup

  • If possible provide a Log and either attach them or use the Code Tag.Consult the Troubleshooting Section found within the FAQ if applicable
  • If possible provide the MAC Address or Serial of the device
  • Provide details if the issue is a day 1 issue or only happened after an upgrade or any other relevant details

Whilst providing some of these details may not directly impact any possible answer the community can provide, it does enable Polycom to have an overview of the current software used. In addition other details allow us to check logs or look up a potential support partners if an issue needs to come into support. It also enables us to verify the entitlement for using features.


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


Is this a Trio running the Zoom Room UI aka the Trio does not show the "usual" UI but the Zoom UI instead or some kind of imported configuration?


  • If Zoom UI please open a ticket with Zoom support
  • If standard Polycom please open a support ticket with your reseller as we would need some traces and logs


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 providing your MAC address or your Polycom devices serial will enable us to 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

Steffen Baier
