TraderZones has given you a good answer.
I have a dry copper pair (no dial tone or phone) from AT&T on which runs my DSL . I use a good hardwired switch/firewall that routes to all the PCs. Buy a Majic Jack @ Wal Mart (I have 3 which are routed into a PBX for the house), connect it to a USB on your laptop, download the software. Connect any old hardwired or wireless phone to it and make all the calls you want. I can even Fax thru my setup.
OR
Wireless NIC and surf your neighbors connection with his permission and use Your Magic Jack setup.
