Ifoni ye-Joiwo IP enezici eziningi

Ifoni ye-Joiwo IP ihlanganisa ifoni ye-IP engangeni manzi / Ifoni ye-IP efakazelwa ukuqhuma / Ucingo Lwe-IP Olungazweli.

Iphrothokholi yokuxhumana phakathi kwamanethiwekhi e-IP (Internet Protocol), okungukuthi, iphrothokholi eyenzelwe ukuxhumana kwamanethiwekhi ekhompyutha komunye nomunye, kanye nocingo lwe-IP luyiphrothokholi yokuxhumana eyinhloko nephrothokholi yenethiwekhi ye-IP, kanye nechweba lenethiwekhi (noma i-WiFi) iyi-interface eyinhloko, idivayisi yocingo ezimele enemisebenzi yokudayela nokushaya ucingo, ngokuvamile idinga ukusetshenziswa neswishi yocingo ye-IPPBX noma ne-IMS. Ukukhuluma nje, iyisevisi yokudlulisa izwi ngesikhathi sangempela nge-inthanethi. Kuwubuchwepheshe obusha bezokuxhumana obusebenzisa i-inthanethi ukudlulisa izwi njengendlela yokuxhumana ngezwi.

     Esikhathini esedlule, i-IP telephony yayisetshenziswa kakhulu ku-intranethi yezinkampani ezinkulu. Ochwepheshe bangaphinda basebenzise inethiwekhi efanayo ukuze banikeze idatha namasevisi ezwi. Ngaphezu kokwenza lula ukuphatha, zingandisa ukukhiqiza. Ngenxa yezindleko zayo eziphansi zokuxhumana (imali yokuxhumana nge-inthanethi engamaphesenti angu-6 ngomzuzu, kanye nemali yokuxhumana yamazwe ngamazwe ngezingcingo ezivamile, ezibiza ngaphezu kwamayuan ayishumi ngomzuzu), ibizwa nangokuthi ucingo olushibhile.

Namuhla, imakethe isivele yenze imikhiqizo yefoni ye-IP. Lolu hlobo lomkhiqizo ngokuyisisekelo luhlanganisa ucingo olujwayelekile kanye nesango lezwi. Inombolo ye-akhawunti nephasiwedi kugunyazwe ikheli le-mac leseva ye-softswitch ngocingo, futhi zonke izingcingo zingenziwa ngentambo yenethiwekhi. Ngesikhathi esifanayo, ucingo lwangaphakathi lukhululekile, futhi ucingo olujwayelekile lwe-IP lunemisebenzi elandelayo:

1. I-Call Control Protocol: Iphrothokholi yokusekela i-SIP noma i-H323 protocol,

2. Usekelo lwekhodi yezwi: G.711, G723.1, G.729A,

3, izwi elicacile, isiqinisekiso sezwi se-QoS

4, ukuzivumelanisa nezimo ezihlukahlukene zenethiwekhi, ngena ngempela umsebenzi we-NAT

I-5, isekela iphrothokholi ye-PPP / PPPoE, isekela ukudayela okuzenzakalelayo, umsebenzi wokudayela kabusha wokunqamula

6, ukusekelwa kwe-DNS, iphrothokholi ye-DHCP

I-7, isekela i-static, ikheli le-IP eliguqukayo, isekela ikheli le-IP lomsebenzi wokufunda ohlakaniphile

8, ukwesekwa Web ukuphathwa, Telnet, TFTP ukulayisha

9, isekela inombolo ye-transceiver ye-DTMF

10, isekela inombolo yocingo yokuhlonza i-CID
