Ikhwalithi nokuthembeka kwakuyizindawo ezimbili ezimbi kunayo idumela leVoIP leminyaka edlule. Manje, ezimweni eziningi, zikhona izinsuku lapho ukusebenzisa iVoIP kufana nokuhlola i-walkie-talkies! Kube nokuthuthukiswa okuningi. Kodwa-ke, abantu badonsa kakhulu ngekhwalithi yezwi kuVoIP ngoba asetshenziselwa iminyaka emkhakheni ongenakuqhathaniswa wamafoni asemhlabeni. Nazi izinto eziyinhloko ezithinta ikhwalithi yezwi ku-VoIP nokuthi yini engenziwa ukuze ukwandise ikhwalithi.
I-Bandwidth
Ukuxhumeka kwakho kwe-intanethi kuphelela njalo ohlwini lwezici ezithinta ikhwalithi yezwi kuzingxoxo ze-VoIP. I- bandwidth onayo ngeVoIP iyisihluthulelo sekhwalithi yezwi. Isibonelo, uma uxhumano lwe-dial-up, ungalindeli ikhwalithi enkulu. Ukuxhumeka kwe-broadband kuzosebenza kahle, uma nje kungabonakali, futhi kungabelwe nezinye izinhlelo zokusebenza eziningi zokuxhumana. Ukuxhomekeka komkhawulokudonsa okukodwa kwezingqinamba ezinkulu ze-VoIP.
Izinsiza
Imishini ye- VoIP ye-hardware oyisebenzisayo ingathinta kakhulu ikhwalithi yakho. Imishini yekhwalithi empofu ngokuvamile iyona eshibhile (kodwa hhayi njalo!). Ngakho-ke kuhle ngaso sonke isikhathi ukuthola ulwazi oluningi ngangokunokwenzeka kwi-ATA, router noma nge-IP ngaphambi kokutshala imali bese uqala ukuyisebenzisa. Funda izibuyekezo futhi uxoxe ngazo emaforamu. Kungenzeka futhi ukuthi i-hardware oyikhethayo iyona engcono kakhulu emhlabeni, kodwa namanje, uthola izinkinga - ngoba awusebenzisi i-hardware evumelana nezidingo zakho.
I-ATA / Router Ngokuba i-ATA / Router, udinga ukucabanga ngalokhu okulandelayo:
- Ubuchwepheshe bokucindezela (ama- codecs ) asekelwe
- Ukukhanselwa kwe-Echo, okuyindlela yokunciphisa i-echo
- I-Firewall nokusekelwa kokuphepha
Amafoni efoni
Imvamisa yefoni yakho ye-IP ingabangela ukuphazamiseka nezinye izinto ze-VoIP. Kunezimo eziningi lapho abantu abasebenzisa amafoni angu-5.8 GHz bebezithola izinkinga zekhwalithi yezwi. Lapho zonke izinkinga zokuxazulula izinkinga zihlulekile, ukushintsha ifoni eyodwa ngevolumu ephansi (isib. 2.4 GHz) ukuxazulula inkinga.
Izimo zezulu
Ngezinye izikhathi, izwi lihlehliswa kabi yizinto ezibizwa nge- static , okuyinto kagesi encane 'engcolile' ebizwa ngokuthi i-static ugesi owenziwe emigqeni ye-broadband ngenxa yemvula, imvula enamandla, izimpukane ezinamandla, izimpembelelo zikagesi njll. Lesi static asinakubonakala kakhulu lapho ushaya amafayela noma ulayishe amafayela, yingakho singakhononda ngakho lapho sisebenzisa i-intanethi yedatha naphezu kokuba kube khona; kodwa uma ulalela izwi, kuba ukuphazamisa. Kulula ukuqeda i-static: vula i-hardware yakho (ATA, router noma ifoni) bese uyixhuma futhi. I-static izoba yize.
Umphumela wezimiso zesimo sezulu ekuxhumaneni kwakho akuyona into ongayishintsha. Ungaba nokuphumula okwesikhashana kwezinye izimo, kodwa isikhathi esiningi, kunomhlinzeki wesevisi wakho ukwenza okuthile. Ngezinye izikhathi, ukushintsha izintambo kuxazulula inkinga ngokuphelele, kodwa lokhu kungabiza.
Indawo yehadiwe lakho
Ukungaboni kahle kuyingozi yezwi ngezwi lokuxhumana ngezwi. Ngokuvamile, imishini yeVoIP iphazamisana ngakho ngaleyo ndlela iveza umsindo nezinye izinkinga. Isibonelo, uma i- ATA yakho iseduze kakhulu nomgwaqo wakho we-broadband, ungase uzwe nezinkinga zekhwalithi yezwi. Lokhu kubangelwa impendulo kagesi. Zama ukuzithutha kude komunye nomunye ukuze ususe izingcingo ezifakwe eceleni, u-echoes, wehla izingcingo njll.
Ukucindezelwa: i-codec esetshenzisiwe
I-VoIP idlulisela amaphakethe wedatha wezwi ngefomu elicindezelekile ukuze umthwalo ozodluliselwa ulula. Isofthiwe yokucindezela esetshenziselwa lokhu ibizwa ngokuthi i-codec. Amanye ama-codec ahle kanti amanye aphansi kakhulu. Kulula, codec ngayinye yakhelwe ukusetshenziswa okuqondile. Uma i-codec isetshenziselwa ukuxhumana idinga enye ngaphandle kwalokho okushiwo yona, ikhwalithi izohlupheka. Funda kabanzi kuma-codec lapha .
