Can you try the following.
Resetting your Digital voice adapter
If your Digital Voice adapter or router has stopped working, we may ask you to reset it to check everything's working as intended. To do this:
- Insert a pin or straightened paper clip into the hole labelled “Reset” on your Digital Voice adapter.
- Slightly push and hold it in for up to 20 seconds; or until all the lights, apart from the power light, switch off. Once this happens release the reset button.
Factory reset of the device will take a full 15 minutes and you need to wait until the allotted time has passed for the full factory reset to be completed. After 15 minutes, check your Digital Voice adapter device and try to re-test to check if the issue resolved.
