The base station is what asks for a provisioning file; the handsets that pair to it never touch the network directly.
Factory reset
Returning this phone to defaults
Steps
- Not verified for this specific base station in the sources this help centre draws from. The GRP-series LCD path (MENU, System, Operations, Factory Reset) is a reasonable starting point, but DP-series DECT bases have a different menu tree. Confirm against the DP755 administration guide, or Grandstream support, before relying on a specific key sequence.
If it does not come up
- Confirm the base station, not a handset, has the network cable.
- Confirm the handsets are paired to the base before expecting a line to ring on one of them.
- Confirm a line is assigned to the device in the portal.
- If the base 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.
