Network architecture for routing of adjunct based services

A method for routing adjunct based calls to adjunct sites in a communications network, wherein said adjunct sites are coupled to terminating switches in said network, said method comprising the steps of:

• receiving an adjunct based call at an originating switch of said communications network, the call originating from a caller who is not a member of a customer group, the caller placing the call to a called party that is a member of the customer group;
• accessing a customer database to determine said customer group for said adjunct based call;
• referencing a routing table to determine routing of said adjunct based call to one of said adjunct sites;
• and
• routing said adjunct based call to an adjunct site based jointly on geographic origin of the originating call and said customer group.

A system for routing adjunct based calls in a communications network to adjunct sites, said adjunct sites being coupled to terminating switches in said network, said system comprising:

• an originating switch for receiving an adjunct based call, the call originating from a caller who is not a member of a customer group, the caller placing the call to a called party that is a member of the customer group, wherein the called party subscribes to services of a communications network provider;
• a database accessible by said originating switch for storing the customer group corresponding to said adjunct based call;
• a routing table for storing identification of an adjunct site for routing of said adjunct based call, said identification of said adjunct site based on both a geographic origin of the originating caller and said customer group of said adjunct based call;
• and
• means for routing said adjunct based call based on said identification at said routing table.
