The Trio runs Poly UC Software rather than PVOS, but reads the same boot-server DHCP options as the Edge E series: option 160 first (161 on a Teams/Skype SKU), falling back to option 66.
Factory reset
Returning this phone to defaults
Steps
- Not verified specifically for the Trio 8300 in the sources this help centre draws from. The Edge E menu path (Home, Settings, Advanced, Administration Settings, Restore to Defaults) is built on the same software family, but the Trio's own conference-room interface is not confirmed to match it exactly. Confirm against Poly's Trio 8300 administration guide before relying on a specific menu path.
If it does not come up
- Confirm the phone has a network cable connected.
- Confirm the model recorded for this device matches the label on the console exactly.
- Confirm a line is assigned to the device in the portal.
- If the phone previously worked elsewhere, factory reset it before enrolling.
Not independently verified for this model
The factory reset procedure above is our best documented starting point, not a confirmed keystroke sequence for this exact model. Where it says to confirm something, do that before relying on it on a customer's desk.

Set the matching DHCP option once on your own network, and every Poly phone you plug in after this one finds the platform on its own.
