let's look up those items as they are unfamiliar to me.
Wow a carved wood phone! I like that.
The answering machine and the phone do not need to be physically connected together, they can live in different rooms, as long as there is a phone point in each, or you can use an adaptor as stated.
If the answering machine uses the same tape for incoming and the outgoing message, you rely on your callers to wait while the tape does some gymnastics before they start speaking, in my experience they don't.
