Received incoming call from my son this morning.
Land line rings. CID shows my son's name and number. Answer phone.
Say Hello. Very slight pause. Then hear the recording "call from xxxx to take the call press 1." Press 1 on the handset and the call is connected to my son.
When the call was finished I went to my GV settings. It is still set to Call Screening Off. So, what happened?
