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 also be
used under SIP, but they are implemented differently in SIP than in
H.323. Even though the H.450 standard refers only to H.323,
Supplementary Services are still applicable to the SIP and SPP voip
protocols, in which cases these features are implemented differently.
