Ubumfihlo kumakholi wefoni buba nokukhathazeka okuningi nanamuhla. Esinye isizathu yiyona namba ekhulayo yamathuluzi okukhulumisana kanye nenani elandayo lokukhungatheka kanye nezinsongo. Esinye isizathu yinani lezinkomba zobumfihlo ezihlobene nokuxhumana kwefoni. Ngakho-ke, ingabe uxhumana ngokuphephile nefoni yakho yezwe noma nge- VoIP yakho lokusebenza?
Ukuqala, kudingeka siqonde ukuthi akekho kulezi zindlela ezimbili zokuxhumana eziphephile futhi ezizimele. Iziphathimandla zingakwazi ukuxhuma izingxoxo zakho kuzo zombili izilungiselelo. Abaqaphi bangakwazi futhi, kodwa nansi umehluko. Abahlaseli bayothola kunzima kakhulu ukugadla futhi bavelele emgqeni wezingcingo kunaseVoIP. Lokhu kusebenza nakumaziphathimandla.
Kuyathakazelisa ukuphawula ukuthi, ngokusho kwezibalo ezivela ku-statista.com, ukuphepha okubonakalayo ngokuphathelene nezindlela zokuxhumana kuningi phakathi kwabantu abasebenzisa ukukhulumisana komhlaba ngokuqhathaniswa nalabo abasebenzisa i-telephony esekelwe kwi-intanethi (cishe amaphesenti angu-60 ngokumelene namaphesenti angu-40). Lokhu kusho ukuthi abantu banombono wokuthi bavikelekile kakhulu ngamakholi wezwe okungekho nge-VoIP.
Cabanga indlela idatha ehamba ngayo ngayinye indlela. Ifoni yendawo ehambisa idatha kusuka emthonjeni kuya endaweni eya kuyo ngokuthi indlela ebizwa ngokuthi ukushintsha kwesifunda. Ngaphambi kokuxhumana nokudluliswa, indlela inqunyelwe futhi izinikele ekukhulumisaneni phakathi komthombo nokuya, phakathi komuntu oshaya ucingo kanye ne-callee. Le ndlela ibizwa ngokuthi isifunda, futhi lesi sifunda sihlala sivaliwe kule kholi kuze kube yilapho omunye oxhumana nabo elele.
Ngakolunye uhlangothi, izingcingo ze-VoIP zenzeka ngokushintshwa kwepakethe, lapho idatha yezwi (manje eseyidijithali) ihlehlisiwe ngokubhalwe phansi futhi kuthiwa 'izikhumba' zibizwa ngokuthi amaphakethe. Lawa maphakethe athunyelwa phezu kwenethiwekhi, okuyi-jungle ye-intanethi, futhi bathola indlela eya endaweni eya kuyo. Amaphakethe angadlula imizila eyahlukene ukusuka kolunye, futhi akukho isifunda esinqunyiwe ngaphambili. Uma amaphakethe afika ku-node yendawo yokuhlala, avuselelwa, abuye aphinde aphethwe yiwo.
Umehluko phakathi kwesifunda nokupakisha iphakethe uchaza umehluko phakathi kwezindleko phakathi kwezingcingo ze- PSTN namakholi we-VoIP, okuvame ukukhululeka.
Lokhu kuchaza nokuthi kungani kulula kubaduni nakwa-eavesdroppers ukuba bachithe idatha ngesikhathi sokuxhumana ngaleyo ndlela bephula ubumfihlo. Amaphakethe asakazwa nge-Inthanethi ngokusebenzisa iziteshi ezingaphephile ayamukelwa kalula kunoma iyiphi i-node. Ngaphezu kwalokho, njengoba idatha yedijithali, ingagcinwa futhi ilandiswe ngezindlela idatha ye-PSTN ayikwazi. I-VoIP isithuthukisiwe kakhulu futhi eyinkimbinkimbi kune-PSTN, izinyathelo zokungena nokubhidliza ubumfihlo ziyinkimbinkimbi kulokhu futhi. Ngaphandle kwalokho, eziningi zezinombolo lapho amaphakethe we-VoIP adlula ayengakulungiswa ukukhulumisana kweVoIP futhi, ngakho-ke, unikeza isiteshi ukuthi sengozini.
Enye indlela yokuthula ngokwengeziwe mayelana nobumfihlo bakho ngesikhathi sezingcingo kanye nokuthumela imiyalezo ukusebenzisa uhlelo lokusebenza nesevisi enikeza ukubethela nokuphepha okuthuthukisiwe. Lawula izinhlelo zokusebenza ezifana ne-Skype ne-WhatsApp, ngaphandle kokunikeza isici sokuphepha (kuze kube manje), saziwa ngezinkinga zokuphepha abanye abazokwazi ukuzenza njengezihlazo. AmaJalimane namaRussia ayazi ngalolu hlobo lokuvikeleka futhi afike nezinhlelo zokusebenza ongazicabangela njengezibonelo: I-Threema, i-Telegram ne-Tox, ukubiza amagama ambalwa nje.
