A method and apparatus for providing real time updates of a database describing the features of individual terminals of a shared plan telecommunications group for communication sessions from and to that individual terminal. The characteristics (numbering plan, incoming and outgoing screening, alternate routing, types of service provided) of each of the individual stations of the shared communication plan are stored in a database accessed through a server. The database can be updated in real time by a designated one of the stations in the shared group. The designated station can also handle appeals for an exception to the restrictions stored in the database. The designated station can receive immediate or periodic information on activity of individual stations, or can receive such information on request. Advantageously, updates of the database can be implemented immediately and economically without requiring assistance of the personnel of the carrier, and the designated station can control communications for the group.
