  • relayReferIfNoMatchForCallId: SBC tries to match the received call-Id. If  a match is found, SBC translates the replaces header and relays the REFER. If there is no match found for call-id, SBC relays the replaces without any changes.
  • relayReferWithoutMatching: SBC always relays the replaces in refer-to without searching for match of call-id.
