Method and system for determining authorization levels in a virtual private network (VPN)
First Claim
1. A method comprising:
- determining whether a call originated from an originating station associated with a virtual private network, the call originating via a private branch exchange associated with the virtual private network by a first user of a plurality of users associated with the virtual private network;
querying, with a service switching point, a private-number table based on a switch identifier representing the service switching point, a trunk group identifier representing the private branch exchange, and an originating station identifier representing the originating station to obtain a private number assigned to the first user;
matching a calling party identifier of an incoming transaction capabilities application part message to an originating station identifier entry in the private-number table;
identifying an authorization level associated with the private number;
comparing the authorization level to a threshold to determine whether to prompt the first user to enter an authorization code; and
providing the authorization level associated with the private number to the service switching point, the service switching point to process the call according to the authorization level.
