Nice to meet you, *****!
Could you please tell me when and how did the problem occur?

Customer Replay

Hi. My land line phone using the Uniden Dect 6.0 system has become locked in a "line in use" situation despite no phone being in use


Got it. What troubleshooting have you done so far?

Customer Replay

it occurred a couple of hours ago and seems to be as a result of trying to add an additional cordless phone extension

Thank you for the info.
Did you try to reset your Uniden Dect 6.0?

Customer Replay


*****, "Line in use" is displayed if the line is currently active on a call. Confirm no one else is on the line. If you have multiple handsets, it is possible that one of them is turned on so check the rest of the handset and turn it off.

Customer Replay

No handset is in use. all have been checked.

Good, thank you for the additional information.
Have you tried to restart your Telstra smart modem? It can be the reason also.

Unplug it for 60 seconds and then plug it back in, please.

Customer Replay

OK will do it now but presumably it will als cut out this connection?

If it is the only internet you are using - yes.

The system has come back on of its own accord before I turned off the modem !!!!!!

So it is already working properly?

Customer Replay

It would appear so. Now I have to try and connect in the new extension handpiece

Yes, try it, please.

Customer Replay

It all seems to be working thank you and Iwill try to work out how to connect the extra
extension in due course.
