1. A communication system for routing calls based on the cost of the calls, the system comprising:

  • (a) a wireless transmit/receive unit (WTRU) including a wireless service platform and a call cost database;

    (b) a wireless base station;

    (c) a first cordless land-line unit including a cordless service platform; and

    (d) a second cordless land-line unit including a cordless interface that is configured to selectively interact with the cordless service platform of the first cordless land-line unit and the wireless service platform of the WTRU, wherein a call placed by the second cordless land-line unit is routed to a wireless service platform of the WTRU, which in turn forwards the call to the wireless base station without using the first cordless land-line unit, instead of routing the call via the first cordless land-line unit, when the call cost database in the WTRU indicates that it is less costly to route the call via the WTRU and the wireless base station than routing the call via the first cordless land-line unit.
