My parents have had the same BT phone (model 8600) for a few years, which has the True Call 100% nuisance blocker functionality, where callers need to announce who they are before they call is transferred.
Recently the phone stopped allowing them to accept incoming announced calls. Usually, after the caller is put through, my parents would use '1' button to speak to them. However the 1 button seemed to have stopped working, and the call would just ring out.
We assumed this may be down to a faulty handset, so we replaced it with a new one which is an updated model as the one they had previously (090632). However the issue is still present! They can accept calls from known callers in their directory, can ring out with no issue, however they cannot accept an announced call using '1'.
The fact they have had the same issues with 2 handsets suggests they are not the problem. The fact that they can ring out / accept known numbers suggests that its not a line issue. However I am not sure how the True Call functionality works / how the announced calls are controlled and connected.
Their landline is managed by Now TV - so I am having an issue between them and BT on who can advise / check this, and as True Call just provide the software to BT (I assume) I cannot speak to them to query this.
I also tested their old handset on my landline and although I have reset it and set it to 'announce', withheld calls are coming through without any challenge as shown as 'Unknown', so I really am at a loss!! Please help!!
