Abstract
A routing table enables a particular long distance carrier for a particular long distance or international destination at a particular time. Different entries in the routing table correspond to different days and times for different long distance and international destinations. If a subscriber dials a number corresponding to the information in the routing table, the carrier corresponding to that information is used to carry the call, instead of the subscriber's default carrier. If the subscriber dials a number that does not correspond to an entry in the routing table, then the default carrier is used to carry the call.

A system for routing a call from a calling party to a called party using a carrier within a telecommunications network, comprising:
- a central office for receiving an incoming call request comprising a destination prefix from the calling party;
- a storage device for storing a subscriber-generated routing table comprising a set of routing instructions comprising a plurality of carriers and associated destination prefixes;
- and
- a controller for determining the carrier based on the destination prefix and the subscriber-generated routing table, and for routing the call to the called party using the carrier.
