I-Telephony ibinzana elithi libonisa iteknoloji evumela abantu ukuba banxibelelwano lwegama elide. Ivela kwigama elithi 'yocingo' elalivela kumagama amabini ngesiGrike esithi "tele," oku kuthetha ukuba kude, kwaye "ifowuni," oku kuthetha ukuthetha, ngoko ke imbono yokuthetha ukusuka kude. Ububanzi bekota sele bwandiswe ngokuza kwezobuchwepheshe ezahlukeneyo zoqhagamshelwano. Ngomlinganiselo walo obanzi, imiqathango ibandakanya ukunxibelelana ngefowuni, ukufowunelwa kwe-Intanethi, ukunxibelelana ngomnxeba, ifeksi, i- voicemail kunye neenkomfa zevidiyo. Ekugqibeleni kunzima ukudweba umgca ocacileyo ukuba yiyiphi i-telephony kunye nento engekho.
Iingcamango zokuqala ukuba i-telephony iya kubuya kwi-POTS (inkonzo yefowuni endala), ebizwa ngokuba yi- PSTN (inethiwekhi yocingo yomnxeba kawonkewonke). Le nkqubo ibuyiselwa ngumngeni omkhulu kwaye ngokukhululeka ekunikezeni iteknoloji ye-IP (VoIP), ebizwa ngokuba yi-IP Telephony kunye ne-Intanethi ye-Intanethi.
Izwi phezu kwe-IP (VoIP) kunye ne-Intanethi ye-Intanethi
La magama mabini asetyenziswa ngokungafaniyo kwiimeko ezininzi, kodwa ngokuthetha ngokwemigaqo, ayenjalo into efanayo. Le mibandela emithathu eyenziwa ngabanye iLizwi phezu kwe-IP, IP Telephony kunye ne-Intanethi ye-Intanethi. Bonke babhekisela ekutshweni kweefowuni zezwi kunye nedatha yezwi ngokusebenzisa ii- IP amanethiwekhi, okuyi- LAN kunye ne-Intanethi. Ngale ndlela, izakhiwo ezikhoyo kunye nezibonelelo ezisele zisetyenziselwa ukuhanjiswa kwedatha zixhunyiwe, ngaloo ndlela ziphelisa iindleko zokuzinikezela kwexabiso elibi njengoko kunjalo ne-PSTN. Inzuzo ephambili yokuba iVoIP izisa kubasebenzisi iinqununu ezinkulu zokusika. Iifowuni zihlala zikhululekile.
Oku kunye neenzuzo ezininzi ezenza iVoIP ibangele ukuba le nto yokugqibela ibe yinto ebonakalayo yitheknoloji eye yafumana ukuthandwa kwehlabathi lonke kwaye yabamba isabelo seengonyama somrhwebo we-telephony. Ixesha le-Computer Telephony liye lavela ngokuza kweefowuni , ezizicelo ezifakwe kwikhomputha, ukufanisa ifowuni, isebenzisa iinkonzo ze-VoIP kwi-Intanethi. I-telephony yekhompyutheni iye yathandwa kakhulu kuba abaninzi abantu bayisebenzisela mahhala.
Ifoni yeTelefoni
Ngubani ongathwali i-telephony epokothini lawo namhlanje? Iifowuni zeefowuni kunye neefowuni ziqhelekileyo zisebenzisa amanethiwekhi omnatha usebenzisa iteknoloji ye-GSM (yeselula) ukuvumela ukuba wenze iifowuni ekuhambeni. Ukubiza kwe-GSM kuninzi kubiza, kodwa iVoIP nayo yahlasela iifowuni zefowuni, ii-smartphones, ii-PC pocket kunye nezinye iifowuni, ezivumela abasebenzisi baselula ukuba benze ixabiso elincinci kwaye ngamanye amaxesha bakhupha ii-call zangaphakathi nakwamanye amazwe. Nge-VoIP yeselula, i- Wi-Fi kunye ne- 3G ubuchwepheshe buvumela abasebenzisi ukuba benze iifowuni ezingenasiphelo, nakwabafowunelwa ngaphandle.
Izixhobo zeTelephony kunye neemfuneko
Yintoni efunekayo kwi-telephony ibonakala phakathi kwezinto ezibonakalayo ezilula ukuya kwizixhobo ezinzima. Masihlale kwicala lomxhasi (kwicala lakho njengomthengi) ukuze ugweme ubunzima bePBX kunye namaseva kunye nokutshintshana.
Kwi-PSTN, ufuna kuphela ifowuni isetyenziswe kunye nodonga lwodonga. Nge-VoIP, imfuno ebalulekileyo uxhumano kwiinkonzo ze-IP (umz. U- Ethernet okanye uxhumano lwe-Wi-Fi ukuya kwi- LAN ), uxhumano lwe-intanethi kwi-intanethi kwaye, xa kuthengiswa nge-telephony yeselula, uxhumano lwe-wireless wire like Wi-Fi, 3G kunye kwezinye iimeko ze-GSM. Izixhobo zingaba zilula njenge-headset (yekhompyutoni ye-computer). Kulabo bafuna ukulungelelaniswa kwefowuni ngaphandle kwekhompyutha, badinga i-ATA (ebizwa ngokuba yi-adapter yefowuni) kunye nefowuni yesintu elula. Ifowuni ye-IP iyona fowuni ekhethekileyo equka ukusebenza kwe-ATA kunye nezinye iimpawu kwaye ngoko ke kunokusebenza ngaphandle kokuxhomekeka kwezinye iirdware.
Akuphela nje ilizwi
Ekubeni amajelo eendaba adibanisa kwijeli enye, i-faxing kunye ne-video conferencing nayo iphantsi kwe-banfony banner. Ifeksi isebenzisa ngokuqhelekileyo umgca wefowuni kunye neenombolo zefowuni ukuhambisa i-facsimile (efutshane ngefeksi) imiyalezo. IP Faxing isebenzisa amanethiwekhi e-IP kunye ne-Intanethi ukuthumela nokufumana imiyalezo yefeksi. Oku kunika inzuzo eninzi, kodwa ijongene nemingeni ethile. I-conferencing yeVidiyo isebenza ngendlela efanayo nezwi le-IP kunye nevidiyo enexesha langempela.
