Abstract
A method and system for providing intelligent network control services in IP telephony, wherein the system includes a location manager and an IP telephony proxy server. The location manager includes an interface to a legacy telephony service control entity and the IP telephony proxy server includes an IP interface to the location manager. If the IP telephony proxy server requires intelligent network services, then the IP telephony proxy server sends an IP telephony session initiation request to the called party at the location manager. The location manager uses the information to query the legacy telephony service control entity for routing information. When the location manager receives a routing response from the service control entity, the location manager maps the response to an IP telephony session control message back to the IP telephony proxy server.

2. A system comprising:
-
a call control entity comprising;
a first device to;
receive a first Session Initiation Protocol (SIP) invite request for a first called party, determine whether the first SIP invite request is associated with an intelligent network service, and send a second SIP invite request when the first SIP invite request is associated with an intelligent network service, and a second device to;
receive an H.323 call establishment request for a second called party, determine whether the H.323 call establishment request is associated with an intelligent network service, and send a third SIP invite request when the H.323 call establishment request is associated with an intelligent network service; and
a location manager to;
receive the second SIP invite request, acquire a first address for the first called party, send the first address to the first device, receive the third SIP invite request, acquire a second address for the second called party, and send the second address to the second device. - View Dependent Claims (3, 4, 5, 6, 7, 8)

9. A system comprising:
-
an H.323 device to;
receive an H.323 call establishment request, the H.323 call establishment request being associated with an intelligent network service, send a first Session Initiation Protocol (SIP) invite request in response to receiving the H.323 call establishment request that is associated with an intelligent network service; and
a location manager to;
receive the first SIP invite request from the H.323 device, obtain, in response to receiving the first SIP invite request, an address for a called party at an egress Internet Protocol (IP) telephony device, and send the obtained address to the H.323 device, the H.323 device establishing a telephone call using the obtained address. - View Dependent Claims (10, 11, 12, 13, 14)
