For me, if it is a line and it goes through the land (i.e. by wire/fiber), then it is a landline. As opposed to signals going through the air, i.e. by radio. Except in very special cases, like emergency phones in ships, it is never a direct connection, there are at least amplifiers in the middle. So between a direct connection from the microphone to the speaker at the other end and VoIP, where do you draw the line? (pun not intended)
