Umgangatho kunye nokuthembeka kwakuyiindawo ezimbini ezinobumnyama kwi-VoIP idumela leminyaka edluleyo. Ngoku, kwiimeko ezininzi, zihamba iintsuku xa ukusebenzisa iVoIP kwakufana nokuhlola i-walkie-talkies! Kukho uphuculo oluninzi. Kodwa kunjalo, abantu banomdla kakhulu ngekhwalithi yezwi kwiVoIP kuba basebenzise iminyaka kwimilinganiselo engaphethekiyo yeefowuni zomhlaba. Nazi izinto eziphambili ezichaphazela umgangatho wezwi kwiVoIP kwaye yintoni enokwenziwa ukukhulisa umgangatho.
Bandwidth
Ikhonkco yakho ye-Intanethi isoloko iphakamisa uluhlu lwezinto ezichaphazela ikhwalithi yezwi kwiintetho zeVoIP. I- bandwidth onayo ngeVoIP iyona nto ebalulekileyo kumgangatho wezwi. Ngokomzekelo, ukuba unxibelelwano lwe-dial-up, ungalindelanga umgangatho ophezulu. Unxibelelwano olubanzi lwebhanki luya kusebenza ngokufanelekileyo, ngokungakhathaliseki ukuba alukho ndawo, kwaye lukwabelwana kunye nezinye izicelo ezininzi zonxibelelwano. Ukuxhomekeka komda we-Bandwidth enye yezinto ezingundoqo zokungaphumeleli kweVoIP.
Izixhobo
Izixhobo zokusebenza zeVoIP ezisetyenziswayo zinokuchaphazela kakhulu umgangatho wakho. Izixhobo ezisemgangathweni eziyimpumelelo ziqhelekileyo zixabiso elincinci (kodwa kungekho njalo!). Ngoko ke kukusoloko kulungile ukuba nolwazi oluninzi kangangoko kunokwenzeka kwi-ATA, router okanye IP yefowuni ngaphambi kokuba utyalomali kwaye uqale ukuyisebenzisa. Funda ukuphononongwa kwaye uxoxe ngawo kwiifom. Kungenzeka ukuba i-hardware oyikhethayo yinto efanelekileyo kwihlabathi, kodwa kunjalo, ufumana iingxaki-kuba awusebenzisi i-hardware ehambelana neemfuno zakho.
I-ATA / Router Ngokuba i-ATA / Router, kufuneka ucinge ngale ilandelayo:
- Iikhompyutheni zoxinzelelo ( codecs ) ezixhaswe
- Ukukhanselwa kwe-Echo, leyo yindlela yokunciphisa i-echo
- I-firewall kunye nenkxaso yokukhusela
Iifowuni zefowuni
Ubume befowuni yakho ye-IP kunokubangela ukuphazamiseka nezinye izixhobo zeVoIP. Kukho imeko ezininzi apho abantu basebenzisa iifowuni ezingama-5.8 ze-GHz baye bafumana iingxaki zezinga lezwi. Xa zonke iingxaki zengxaki zihlulekile, ukutshintsha ifowuni enye ngefayile ephantsi (umz. 2.4 GHz) ukuxazulula ingxaki.
Izimo zeMimoya
Ngamanye amaxesha, ilizwi liphazamiseka kakhulu ngento ebizwa ngokuba yi- static , eyinto encane engcolileyo yokhula eveliswe kumigca ebanzi ngenxa yeendudumo, imvula enamandla, iinguqu ezinamandla, iimpembelelo zombane njl. Le static ayibonakali kakhulu xa ukukhwaza umnatha okanye ukukhuphela iifayile, yingakho asikhalazi ngalo xa sisebenzisa i-intanethi yedatha nangona ilapha; kodwa xa uphulaphule ilizwi, kuphazamiseka. Kulula ukuqeda i-static: cima i-hardware yakho (ATA, router okanye ifowuni) kwaye uyixube kwakhona. I-static iya kuveliswa ize.
Isiphumo seemeko zemozulu ekuxhumene kwakho akuyona into ongayitshintsha. Unokufumana uncedo lwexesha elifutshane kwezinye iimeko, kodwa ixesha elininzi, kunika umnikezeli wesevisi ukuba enze into ethile. Ngamanye amaxesha, ukutshintsha iingcingo kusombulula ngokupheleleyo ingxaki, kodwa oku kungabiza.
Indawo ye-hardware yakho
Ukuchithwa kuyingozi yomsindo ngelizwi loqhagamshelwano. Ngokuqhelekileyo, izixhobo zeVoIP ziphazamisana kunye nokuvelisa ingxolo nezinye iingxaki. Ngokomzekelo, ukuba i- ATA yakho isondele kakhulu kumtya wakho wendlela ebanzi, unokufumana iingxaki zekhwalithi yezwi. Oku kubangelwa yimpendulo yombane. Zama ukuzitshintshana kude komnye ukuze ulawule iifowuni ezigwenxa, u-echoes, wehla iifowuni, njl.
Ukunyanzeliswa: i-codec esetyenziswayo
I-VoIP idlulisela iipakethe zedatha yezwi kwifomu ecindezelweyo ukuze umthwalo uhanjiswe. Iprogram yoxinzelelo esetyenziselwa le nto ibizwa ngokuba yi-codec. Ezinye i-codec zilungile ngelixa ezinye zingekho kakuhle. Kulula nje, nganye i-codec yenzelwe ukusetyenziswa okuthe ngqo. Ukuba i-codec isetyenziselwa unxibelelwano idinga enye ngaphandle kokuba leyo ithetha ngayo, umgangatho uya kuhlupheka. Funda kabanzi kwiikodec apha .
