ABSTRACT:
A method and system for processing a call in a telecommunications network comprising a signalling system interconnecting a switch, a segmentation directory and at least one service processor for processing a call associated with a particular service or feature provided by the telecommunications network. The switch receives the call and information associated with the call and transmits a first query message to the segmentation directory. The segmentation directory determines whether the call requires processing by a service processor, and if so, identifies a service processor capable of processing the call. The segmentation directory also determines whether a second query message may be transmitted from the segmentation directory to the identified service processor over the signalling system and, if the second query message cannot be transmitted from the segmentation directory to the identified service processor, the segmentation directory transmits a response message to the switch instructing the switch to transmit a third query message over the signalling system to the identified service processor.
