This weekend at about 12:30, I arrived home to find two messages
on my answer phone from the boss asking for help with his
laptop. So, incoming calls OK.

Is this coincidence? Is there a reason for lost dial tone? All I
could think of was an off-the-hook phone, but we had received
incoming calls while absent.

Could it be that the second incoming call didn't release
the line properly?
