It depends on the technology and the carrier.

A simple POTS line and you're out of luck.

If you have a T1 (i.e. ISDN-PRI) and a co-operative carrier, it may just 
work or they may enable it if requested.

You could always use a co-operative SIP carrier (like Vitelity). A penny 
or 2 per minute will keep your someone happy.
