Can receive calls but unable to make calls due to engaged tone

[hkymre]

My elderly parents have recently been upgraded to DV

They have the converter & have been using their old phones with no issues for the last weeks.

Now though they can't make calls due to an engaged tone.
Tried dialling 1571 as suggested elsewhere, but it doesn't dial

Rebooted the hub, the converter, the phone but no joy.

In the end, I've taken them my Advanced Digital Home Phone & set that up.
That works fine & can make and receive calls
The old phone still has an engaged tone.

Any ideas on how to fix it?
