VOLTE: IFC (Initial Filter Criteria)

0 votes

On which stage the S-CSCF obtain the IFCs from the HSS?
Is it on UE SIP registration or per each call attempt?

In case the IFCs indicates that the S-CSSF should orchestrate the SIP session to two (or more) application server, is there an option to indicate (into the IFCs) that a specific AS should be involved only on specific situation such as: "only in roaming", "only if the dialed number length limited to X digits"
