Polycom Trio 8500 Bluetooth issue - Call starts automatically

Hi Guys,


I have an issue with our Trio 8500 (

The issue is that  connecting over bluetooth "starts a call" automatically.


i tried downgrading the firmware to the previous version, and playing with bluettoths settings.

didn't work.


The connection creates two audio devices, "stereo" and "handsfree".

when unselecting "handsfree" in Bluetooth setting, 

  • Stereo doesn't allow me to send voice, which is understandable.

selecting both, Stereo and handsfree, "starts a call" automatically.


This issue prevents me to use the phone for anything else. not even another call.

The call starts automatically even after "hanging up"


The message on screen says "Bluetooth-Audio" and when pressing the home button, the message on top of the screen says "return to call"

Hello @Ericg ,


Welcome to the Poly Community.

  • Is this a Day 1 issue?
  • Why was the mobile phone paired with the Trio aka what is the use case?
  • What is the mobile phone and what OS?
  • Has the Mobile phone been restarted already as an App running on it may trigger this?


The next step would be to open a ticket.

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.

If this is some sort of an Internet discounter providing your MAC address or your Poly devices serial will enable us to look up who would be able to support you. This may not be who you purchased the Poly device from.

If the unit is no longer within the warranty please be prepared to Pay Per Incident / PPI. This is all outlined in detail here

Hi Steffen,


It is not a day 1 issue, I believe it may be related to a software upgrade.

I will contact our reseller for help.
