I am enquiring about something that happened recently to a friend.
She had been called by someone, a friend, and once the call was finished she hung up, as usual.
She then went to make a call, got dialling tone and phoned someone else.
Later she met the first caller down the street who told her that she had heard her phone call conversation with the second caller.
Is this possible?
Has her phone been hacked or tapped?
Is it illegal to listen in on others calls?
Thank you for any advice.
