You should get an IP address with user name/ password from the provider.

You will get only IP address for authorization.

What are FXO and FXS?
FXS (Foreign exchange Station) is an interface which drives an analog
telephone or FAX machine. FXS interfaces deliver power, provide ringing, and
use FXO signaling. FXS interfaces are what allow you to hook telephones and
other analog devices to your PBX
FXO (Foreign exchange Office) is an interface that connects to a phone line to
supply your PBX with access to a public telephone network. FXO interfaces use
FXS signaling. FXO interfaces allow you to connect your PBX to real analog
phone lines.
