Supplementary Services features derive from the H.450 standard,
which brings to voip telephony functionality once only available with
PSTN or PBX telephony. Supplementary Services features can be used
under H.323 only and not under SIP. Even though the H.450 standard
refers only to H.323, Supplementary Services are still applicable to the
SIP and SPP voip protocols.
