25. A computer program product comprising computer-executable instructions embodied in a computer-readable medium for performing steps comprising: (a) receiving a signaling message that contains a global title address (GTA); (b) selecting a GTT mode from a plurality of different GTT modes based on an attribute of the received signaling message, wherein at least some of the different GTT modes use different combinations of address parameters associated with received signaling messages to search a GTT database, wherein each of the different GTT modes translates at least a signaling connection control part (SCCP) parameter into at least a message transfer part (MTP) destination point code; and (c) searching the GTT database using a combination of address parameters of the received signaling message specific to the selected GTT mode.

The computer program product of claim 25 wherein searching the GTT database using a combination of address parameters of the received signaling message specific to the selected GTT mode includes searching the GTT database using at least one of: an incoming linkset of the received signaling message, an origination point code (OPC) of the received signaling message, a destination point code (DPC) of the received signaling message, a calling party address of the received signaling message, and a called party address of the received signaling message.
