Landline caller display and spoofed calls?
A few months back our landline stopped working. I suspect we had been switched to the fibre side without notification and they were "fixing" the issue based on calls. The "fix" was a simple matter of swapping phone base-stations around, plugging into the Hub and configuring it.
However since then we seem to have had more calls from people pretending to be Microsoft Support, some of which have turned offensive. The mildest was when I was called handsome, or so she said. The word she used initially translates to "idiot".
The phone displays a caller ID. I believe it has been possible to spoof this ID. Is that still possible on the fibre landline? If the caller IDs are valid I will start reporting them.
