I am remodeling an old house and in some of the rooms on the baseboard are
very old phone jacks. However in the living room and family rooms, they
installed two jacks, like below:

I am trying to figure out why. I do not have the phone line turned on yet,
since the house will be worked on for the next six months and not inhabited,
I don't see the need to pay for a land line for six months. But I would
like to move the jacks into the wall which is not a big deal just need to
get a small box and some drywall patching is all that is necessary.

However, I wonder if these two jacks mean there are two separate lines. Is
there a way to tell?

Thanks,

MC
