ABSTRACT:
A telecommunication network includes a first local exchange carrier (LEC) switch that provides service to first subscribers. A first signal from the first switch is received at a second telecommunication switch disposed at a hierarchical level above the first switch. The first signal indicates to the second switch that call origination services are to be provided directly by the second switch for one of the first subscribers. A second signal is received at the second switch via the first switch indicative of the identification of the one first subscriber. A record in a database coupled to the second switch is located in response to receiving the second signal. A group affiliation parameter stored in said record is identified; the group affiliation parameter defines one organization of which the one first subscriber is a member. The second switch transmits a call setup message to a third switch associated with the second subscriber. The call setup message includes the group affiliation parameter so that the first subscriber's membership in the one organization can be used in further call processing.
