A week ago all worked perfect with my house phone and answering machine.
Suddenly it has been infected by an external system which blocks my answering machine with a "call divert".

Making a call with my mobile, a message now comes up saying "Note - incoming call diverts.
If I pick up the phone while it is ringing, I can talk normally to the caller. But once the ringing tone has stopped the caller is told they cannot leave a message and to ring off.

I can make calls still with no problem.

Has anybody got an explanation why this problem has suddenly occurred and knows how to fix it ?
