A METHOD AND APPARATUS FOR LINKING IDENTIFICATION DATA TO A CALL BETWEEN NETWORKS

摘要

A method and apparatus for linking caller identification data to a call that originates from a virtual private network is disclosed. Steps relating to the method receiving a call, including an identifier at a mobile switching center. The identifier would identify a termination point that initiated the call. Often times a call going through a VPN such as a private branch exchange (PBX) would only display call identification data of the PBX. For example, an outgoing call from Company A' s enterprise phone system may state the company' s main phone number instead of the actual phone number of the person calling. Furthermore, in the name information block, Company A would be displayed instead of Employee A. The system and method disclosed allows for this data to be filled with more precise information.
