Shared Initial Filter Criteria (SiFC)
If both the HSS and the S-CSCF support this feature, subsets of iFC may be shared by several service profiles. The HSS
downloads the unique identifiers of the shared iFC sets to the S-CSCF. The S-CSCF uses a locally administered
database to map the downloaded identifiers onto the shared iFC sets.
If the S-CSCF does not support this feature, the HSS will not download identifiers of shared iFC sets.
