SIP inomirira Session Initiation Protocol. Inowirirana neVoIP sezvo inopa zviratidzo zvekuita nayo. Kunze kweVoIP, inoshandiswa kune dzimwe mhando dzemitambo yemagetsi pamwe chete, semitambo yepaIndaneti, mavhidhiyo nemamwe mabasa. SIP yakagadzirwa pamwe chete nemamwe mararamiro emitoti, H.323, iyo yakashandiswa sechiratidzo chekufananidzira kweVoIP pamberi peSIP. Iye zvino, SIP yakashandura iyo yakawanda.
SIP inobata nguva yekukurukurirana, iyo ndiyo nguva yenguva iyo mapato anotaurirana. Izvi zvinosanganisira inhare yefoni yeInternet, hurukuro ye multimedia uye kuparadzirwa, pamwe chete. SIP inopa chiratidzo chakakosha pakusika, kugadzirisa uye kupedza zvidzidzo nemumwe kana vatauriri vakawanda vanotaurirana.
SIP inoshanda nenzira yakafanana nenzira yakafanana nedzimwe nhepfenyuro dzakafanana seHTTP kana SMTP . Inotakura chiratidzo kuburikidza nokutumira zvinyorwa zvishoma, zvinosanganisira musoro uye muviri.
SIP Mabasa
SIP inobatsira-protocol yeVoIP neTerephony zvachose, nekuda kwezvinhu zvinotevera zvine:
Zita Shanduro uye Mushandisi Nzvimbo: SIP inoshandura kero kune zita uye nokudaro inosvika kune iyo inonzi bato pane chero nzvimbo. Iyo inoita mapepa ekutsanangurwa kwemugovera kune nzvimbo, uye inovimbisa kutsigirwa kwemashoko ehutano hwekudanwa.
Taura nhauriro: Haasi mapoka ose ekukurukurirana (angave ari anopfuura maviri) ane zvinhu zvinodiwa. Somuenzaniso, havasi vose vanogona kunge vane mavhidhiyo. SIP inobvumira boka racho kutaurirana kwezvinhu.
Danaidza vatungamiri vekutora : SIP inobvumira munhu anenge apinda chikamu kuti aite kana kubvisa kushamwaridzana kune vamwe vashandisi panguva yefonero. Vashandi vanogonawo kuendeswa kana kuiswa panzvimbo.
Dhidzai maitiro anochinja: SIP inobvumira mushandisi kuchinja unhu hwemafoni panguva yekufonera. Semuenzaniso, sevashandisi, iwe unogona kuve wakwanisa kubvisa vhidhiyo, kunyanya apo mushandisi mutsva anosangana nechitsauko.
Media negotiation: Iyi nzira inobvumira kukurukurirana kwemasvikiro anoshandiswa mukufonera, sekusarudza codec yakakodzera yekufambiswa kwefonyo pakati pezvigadzirwa zvakasiyana-siyana.
Chimiro cheSIP mharidzo
SIP inoshanda kuburikidza nekutaura zviyero zvekutaurirana kutumira uye kugamuchira zvinyorwa. Mharidzo yeSIP inotakura mashoko akawanda anobatsira kuziva nguva, kuronga nguva, uye kutsanangura mhizha. Pasi pane urongwa hwemashoko anonyatsoratidza:
- Zvinyorwa zvinyorwa (eg version)
- Session information (muumbi, zita nezita)
- Nhaurirano yevadzidzi (email, foni nezvimwewo)
- Bandwidth information
- Encryption information
- Nguva inotsanangurwa (nguva inoshanda uye kudzokorora nguva)
- Mharidzo tsanangudzo (zita remashoko, musoro, kero, etc.)
- Media bandwidth information
- Media encryption key
