I-SIP imelela iSto Protocol Initiation Protocol. Ihambisana neVoIP ngoba inikeza imisebenzi yokubonisa kuyo. Ngaphandle kwe-VoIP, isetshenziswe kwezinye ubuchwepheshe be-multimedia, njengamageyimu e-intanethi, ividiyo namanye amasevisi. I-SIP yasungulwa kanye nezinye izinqubo zokubonisa, i-H.323, eyasetshenziswa njenge- protocol yokubonisa ye-VoIP ngaphambi kwe-SIP. Manje, i-SIP isisuse endaweni enkulu.
I-SIP isebenza ngezikhathi zokuxhumana, okuyizinkathi zesikhathi lapho amaqembu axhumana khona. Lokhu kufaka phakathi izingcingo zezingcingo ze-Inthanethi, izingqungquthela ze-multimedia nokusabalalisa njll. SIP inikeza ukubonakaliswa okudingekayo ekudaleni, ekuguquleni nasekuqedeni amaseshini nomunye oyedwa noma oxhumana nabo abaningi.
I-SIP isebenza cishe ngendlela efanayo namanye ama- protocol ajwayelekile afana ne-HTTP noma i- SMTP . It enza ukubonakaliswa ngokuthumela imiyalezo emincane, ehlanganisa inhloko nomzimba.
Imisebenzi ye-SIP
I-SIP iyinsiza-ye-protocol ye-VoIP ne-Telephony ngokujwayelekile, ngenxa yezici ezilandelayo:
Indawo Yokuhumusha Nendawo Yomsebenzisi: I- SIP ihumusha ikheli egameni futhi ngaleyo ndlela ifinyelela ebizwa ngokuthi iqembu kunoma iyiphi indawo. Yenza imephu yencazelo yeseshini endaweni, futhi iqinisekisa ukwesekwa ngemininingwane yendlela yokushaya ucingo.
Ukuxoxisana ngesici: Akuzona zonke izingxenye zokuxhumana (okungenzeka zibe ngaphezu kwezingu-2) ezinezici ezidingekayo. Isibonelo, akuwona wonke umuntu ongase abe nokusekelwa kwevidiyo. I-SIP ivumela iqembu ukuthi lixoxisane ngezici.
Shayela ukuphathwa kwabahlanganyeli: I- SIP ivumela umhlanganyeli ukuthi enze noma akhansele ukuxhumana kwabanye abasebenzisi ngesikhathi socingo. Abasebenzisi bangadluliselwa noma babelwe.
Izinguquko zesici socingo: I- SIP ivumela umsebenzisi ukuthi ashintshe izici zocingo ngesikhathi socingo. Isibonelo, njengomsebenzisi, ungafuna ukunika amandla ukukhubaza ividiyo, ikakhulu lapho umsebenzisi omusha ejoyina iseshini.
Ukuxoxisana kweMediya: Le ndlela yenza ukuxoxisana kwezindaba ezisetshenziselwa ucingo, njengokukhetha i-codec efanelekile yokusungulwa kocingo phakathi kwamadivayisi ahlukahlukene.
Isakhiwo somlayezo we-SIP
I-SIP isebenza ngokusebenzisa amadivaysi okuxhumana athuma futhi athola imiyalezo. Umlayezo we-SIP unolwazi oluthe xaxa olusiza ukukhomba iseshini, ukulawula isikhathi, nokuchaza abezindaba. Ngezansi uhlu lwalomyalezo oqukethe ngokufushane:
- Ulwazi lwe-Protocol (isib. Inguqulo)
- Ulwazi lweseshini (umdali, igama njll)
- Ulwazi lomhlanganyeli (i-imeyili, ifoni njll)
- Ulwazi lomkhawulokudonsa
- Ulwazi lokubethela
- Incazelo yesikhathi (isikhathi esisebenzayo nesikhathi sokuphinda)
- Incazelo yemidiya (igama lezindaba, isihloko, ikheli njll)
- Ulwazi lomkhawulokudonsa kweMediya
- Ikhibhodi yokubhala imidiya
