Isilawuli Somngcele Wesikhathi - Ingxenye Ebalulekile Yokusebenza Okukude
• Isendlalelo
Ngesikhathi sokuqubuka kwe-COVID-19, izincomo "zokusabalalisa umphakathi" ziphoqa iningi labasebenzi bamabhizinisi nezinhlangano ukuthi basebenze ekhaya (WFH). Ngenxa yobuchwepheshe bamuva, manje sekulula ngabantu ukuthi basebenze besuka noma yikuphi ngaphandle kwendawo yamahhovisi endabuko. Ngokusobala, akusona nje isidingo samanje, nekusasa, njengoba izinkampani eziningi ikakhulukazi izinkampani ze-inthanethi zivumela izinduku ukuthi zisebenze zisekhaya futhi zisebenze ngokuguquguqukayo. Ungabambisana kanjani noma yikuphi ngendlela ezinzile, evikelekile futhi ephumelelayo?
Izinselele
Uhlelo locingo lwe-IP luyindlela eyodwa eyinhloko yokuthi amahhovisi akude noma abasebenzisi basekhaya bahlanganyele. Kodwa-ke, ngoxhumo lwe-inthanethi, kuza nezindaba zokuphepha ezimbalwa ezibalulekile - okuyisisekelo ukuvikela futhi izikena ze-SIP ezizama ukungena kumanethiwekhi wamakhasimende wokugcina.
Njengoba abathengisi abaningi besistimu yocingo lwe-IP bathola, izikena ze-SIP zingathola futhi ziqale ukuhlasela ama-IP-PBX axhumeke ku-inthanethi phakathi nehora lokuvula kwawo. Eyethulwe abakhwabanisi bamazwe ngamazwe, izikena ze-SIP zihlale zifuna amaseva e-IP-PBX avikelekile angawagqekeza futhi asebenzise ukuqalisa izingcingo eziwumgunyathi. Umgomo wabo uwukusebenzisa i-IP-PBX yesisulu ukuqalisa izingcingo eziya ezinombolweni zocingo zezinga eliphezulu emazweni angalawulwa kahle. Kubaluleke kakhulu ukuvikela isithwebuli se-SIP neminye imicu.
Futhi, ebhekene yinkimbinkimbi yamanethiwekhi ahlukene kanye namadivayisi amaningi e-SIP avela kubathengisi abahlukene, inkinga yokuxhumana ihlale ibuhlungu. Kubaluleke kakhulu ukuhlala ku-inthanethi futhi uqinisekise ukuthi abasebenzisi befoni bekude bayaxhuma bodwa ngaphandle komthungo.
Isilawuli somngcele weseshini ye-CASHLY (i-SBC) siyilungele lezi zidingo.
• Yini iSession Border Controller (SBC)
Izilawuli zomngcele weSession (SBCs) zitholakala emaphethelweni enethiwekhi yebhizinisi futhi zihlinzeka ngoxhumano oluvikelekile lwezwi nevidiyo kubahlinzeki beziqu ze-Session Initiation Protocol (SIP), abasebenzisi abasemahhovisi egatsha akude, abasebenzi basekhaya/izisebenzi ezikude, kanye nokuxhumana okuhlangene njengesevisi. (UCaaS) abahlinzeki.
Iseshini, kusukela ku-Session Initiation Protocol, ibhekisela ekuxhumaneni kwesikhathi sangempela phakathi kwamaphoyinti okugcina noma abasebenzisi. Lokhu ngokuvamile yikholi yezwi kanye/noma yevidiyo.
Umngcele, isho ukuxhumana phakathi kwamanethiwekhi angathembani ngokugcwele.
Isilawuli, isho ikhono le-SBC lokulawula (ukuvumela, ukuphika, ukuguqula, ukuqeda) iseshini ngayinye enqamula umngcele.
• Izinzuzo
• Ukuxhumana
Izisebenzi ezisebenza ekhaya, noma ezisebenzisa iklayenti le-SIP kumakhalekhukhwini wazo zingabhalisa nge-SBC ziye ku-IP PBX, ukuze abasebenzisi bakwazi ukusebenzisa izandiso zabo ezivamile zamahhovisi njengokungathi bahlezi ehhovisi. I-SBC ihlinzeka ngokunqamula kwe-NAT okukude kumafoni akude kanye nokuphepha okuthuthukisiwe kwenethiwekhi yezinkampani ngaphandle kwesidingo sokusetha imigudu ye-VPN. Lokhu kuzokwenza ukusetha kube lula kakhulu, ikakhulukazi ngalesi sikhathi esikhethekile.
• Ukuphepha
Ukucasha kwe-topology yenethiwekhi: Ama-SBC asebenzisa ukuhumusha ikheli lenethiwekhi (NAT) ezingeni le-Open Systems Interconnection (OSI) Layer 3 Internet Protocol (IP) kanye neleveli ye-OSI Layer 5 SIP ukuze kugcinwe imininingwane yenethiwekhi yangaphakathi ifihliwe.
I-firewall yohlelo lokusebenza lwezwi: Ama-SBC avikela ekuhlaselweni kokunqatshelwa kwesevisi ngocingo (TDoS), ukuhlaselwa kwe-dinal of service (DDoS), ukukhwabanisa nokwebiwa kwesevisi, ukulawula ukufinyelela, nokuqapha.
Ukubethela: Ama-SBC abethela ukusayina nemidiya uma ithrafikhi inqamula amanethiwekhi ebhizinisi kanye ne-inthanethi kusetshenziswa iTransport Layer Security (TLS) / Secure Real-Time Transport Protocol (SRTP).
• Ukuqina
Ukulinganisa kwe-IP trunk load: I-SBC ixhuma endaweni efanayo ngaphezu kweqembu le-SIP elilodwa le-SIP ukuze ibhalansise ukulayishwa kwekholi ngokulinganayo.
Omunye umzila: imizila eminingi eya endaweni efanayo ngaphezu kweqembu elilodwa le-SIP trunk ukuze unqobe ukugcwala, ukungatholakali kwesevisi.
Ukutholakala okuphezulu: 1+1 ukuphindaphindeka kwehadiwe kuqinisekisa ukuqhubeka kwebhizinisi lakho Ukusebenzisana
• Ukusebenzisana
Ukudlulisa amakhodi phakathi kwama-codec ahlukahlukene naphakathi kwama-bitrate ahlukene (isibonelo, ukudlulisa ikhodi ku-G.729 kunethiwekhi yebhizinisi kuya ku-G.711 kunethiwekhi yomhlinzeki wesevisi ye-SIP)
Ukujwayela kwe-SIP ngomlayezo we-SIP kanye nokukhohlisa kwesihloko. Ngisho usebenzisa amatheminali e-SIP abathengisi abahlukene, ngeke kube nenkinga yokuhambisana ngosizo lwe-SBC.
• I-WebRTC Gateway
Ixhuma izindawo zokugcina ze-WebRTC kumadivayisi okungewona awe-WebRTC, njengokushaya usuka kuklayenti le-WebRTC kuya ocingweni oluxhunywe nge-PSTN.
I-CASHLY SBC iyisakhi esibalulekile ebesinganakwa esixazululweni sokusebenza kude nesokusebenzela ekhaya, iqinisekisa ukuxhumana, ukuphepha nokutholakala, inikeza ithuba lokwakha uhlelo locingo lwe-IP oluzinzile noluvikelekile ukusiza abasebenzi basebenzisane ngisho nabo. asezindaweni ezahlukene.
Hlala uxhumekile, usebenza ekhaya, sebenzisana kahle kakhulu.
