Tsanangudzo: H.323 inowanzoenderana nehuwandu hwemashoko ehurumende. H.323 yakagadzirirwa kutsigira nguva chaiyo-kutumirwa kweyodhidhiyo nemavhidhiyo data pane packet network se IP. Mutemo unosanganisira mitemo yakasiyana-siyana inobatanidza zvimwe zvinhu zveInternet telephony . I International Telecommunication Union (ITU-T) inotarisira H.323 uye izvi zvinowirirana.
Mazwi akawanda pamusoro pePI (VoIP) anoshandisa H.323. H.323 inotsigira foni yekugadzira, teardown uye kutumira / kutumira. Architectural elements yeH.323 based system ndiyo Terminals, Multipoint Control Units (MCUs), Gateways, uyo anogadzirirawo Gedhi reMagedhi uye Border Elements. Mabasa akasiyana eH.323 anotarisana pamusoro peTCP kana UDP . Pasi pose, H.323 inokwikwidzana neIndaneti Session Initialization Protocol (SIP), imwe nheyo inopupurirwa inowanikwa muVoIP systems .
Chimwe chinhu chinokosha cheH.323 Chirongwa Chebasa (QoS) . QoS teknolojia inobvumira kunyatsogadziriswa kwemazuva uye kumira kwekutarisana kwemigwagwa kuiswa pa "zvakanaka-effort" pakutevedza maitiro seTCP / IP pamusoro peEthernet. QoS inovandudza kunaka kwezwi kana mavhidhiyo anodyisa.
