Inkcazo:
Ukulahla kubangelwa xa iipakethi zedatha (ilizwi) zithatha ixesha elingaphezulu kunokuba lilindeleke ukuba lifike kwindawo yazo. Oku kubangela ukuphazanyiswa yilizwi eliphezulu. Nangona kunjalo, ukuba isetyenziswe kakuhle, iziphumo zayo zingancitshiswa.
Xa iipakethi zithunyelwa phezu kwenethiwekhi ukuya kumatshini / indawo yefowuni, ezinye zazo zinokulibaziseka. Ukuthembeka kwimiba yekhwalithi yekhwalithi yezwi kukubona ukuba incoko ayifaki ukulinda ipakethe eya ukuya kwindawo ethile eluhlaza. Enyanisweni, kukho ezininzi izinto ezichaphazela uhambo lwamapakethi ukusuka kwindawo eya kwindawo eya kuyo, kwaye enye yazo iyinkqubo engundoqo.
Ipakethi yokulibaziseka ingafika ngokukhawuleza okanye ayiyi kufika, xa ilahlekile. I-QoS (Ubunjani beNkonzo) Iingqalelo zezwi zixhomekeke ekulahlekeni kwepakethe, xa kuthelekiswa nokubhala. Ukuba ulahlekelwa lizwi okanye i-zero kwibhalansi yakho, itekisi yakho ithetha ukuba into ehluke ngokupheleleyo! Ukuba ulahlekelwe "hu" okanye "ha" kwintetho, akenzi impembelelo enkulu kakhulu, ngaphandle kwesinye isithintelo ngekhwalithi yezwi. Ngaphandle koko, i-voice smoothing mechanism iyayilawula ukuze ungayiva.
Xa ipakethe lilibazisekile, uya kuliva ilizwi emva koko. Ukuba ukulibaziseka akulona lukhulu kwaye kuqhubeka, ingxoxo yakho iya kwamkeleka. Ngelishwa, ukulibaziseka akuhlali rhoqo, kwaye kuyahluka ngokuxhomekeka kwezinye izinto zobuchwepheshe. Olu hlobo lokulibazisa lubizwa ngokuba yi- jitter , oludala umonakalo kumgangatho wezwi.
Ukubambezeleka kubangela ukuba ulandele iifowuni zeVoIP.
