Abstract:
Internet protocol (IP) based calls from a first terminal in an IP based communications system are routed to a second terminal in another communications system. In response to a call setup request at a common communications core that is common to both the IP based communications system and the other communications system, a query is transmitted to a private telephone number mapping database that contains routing information for terminals in both the IP based communications system and the other communications system requesting routing information for the second terminal. Routing information for the call setup request is received from the private telephone number mapping database for routing the call.
