Isilawuli Semingcele Yeseshini - Ingxenye Ebalulekile Yokusebenza Kude
• Ingemuva
Ngesikhathi sokuqubuka kwe-COVID-19, izincomo "zokuhlukanisa abantu" ziphoqa iningi labasebenzi bamabhizinisi nezinhlangano ukuthi basebenzele ekhaya (WFH). Ngenxa yobuchwepheshe bamuva, manje sekulula ngabantu ukuthi basebenzele noma kuphi ngaphandle kwendawo yehhovisi evamile. Ngokusobala, akusona nje isidingo samanje, futhi nangesikhathi esizayo, njengoba izinkampani eziningi kakhulu ikakhulukazi izinkampani ze-inthanethi zivumela abasebenzi ukuthi basebenzele ekhaya futhi basebenze ngendlela eguquguqukayo. Ungabambisana kanjani usuka noma kuphi ngendlela ezinzile, ephephile nephumelelayo?
Izinselele
Uhlelo lwe-IP telephony luyindlela eyodwa eyinhloko yokuthi amahhovisi akude noma abasebenzisi abasebenza ekhaya basebenzisane. Kodwa-ke, ngokuxhumeka kwe-inthanethi, kuza nezinkinga eziningana ezibalulekile zokuphepha - okuyinhloko ukuvikela futhi ama-scanner e-SIP azama ukungena kumanethiwekhi amakhasimende okugcina.
Njengoba abathengisi abaningi bezinhlelo ze-IP telephony bethole, ama-scanner e-SIP angathola futhi aqale ukuhlasela ama-IP-PBX axhunywe kwi-inthanethi zingakapheli ihora evuliwe. Aqalwe ngabakhohlisi bamazwe ngamazwe, ama-scanner e-SIP ahlala efuna amaseva e-IP-PBX angavikelwe kahle angawasebenzisa ukuze aqalise izingcingo zokukhwabanisa. Umgomo wawo ukusebenzisa i-IP-PBX yesisulu ukuqala izingcingo eziya ezinombolweni zocingo ezisezingeni eliphezulu emazweni angalawulwa kahle. Kubaluleke kakhulu ukuvikela kuma-scanner e-SIP nakwezinye izingxoxo.
Futhi, njengoba sibhekene nobunzima bamanethiwekhi ahlukene kanye namadivayisi amaningi e-SIP avela kubathengisi abahlukene, inkinga yokuxhumana ihlala iyinkinga. Kubaluleke kakhulu ukuhlala ku-inthanethi nokuqinisekisa ukuthi abasebenzisi befoni abakude baxhumana kahle.
Isilawuli somngcele we-CASHLY session (SBC) silungele kahle lezi zidingo.
• Kuyini iSession Border Controller (SBC)
Abalawuli bemingcele ye-Session (ama-SBC) batholakala emaphethelweni enethiwekhi yebhizinisi futhi bahlinzeka ngokuxhumeka kwezwi nevidiyo okuphephile kubahlinzeki be-trunk ye-Session Initiation Protocol (SIP), abasebenzisi emahhovisi egatsha akude, izisebenzi zasekhaya/izisebenzi ezikude, kanye nabahlinzeki bezokuxhumana abahlanganisiwe njengesevisi (i-UCaaS).
Iseshini, kusukela ku-Session Initiation Protocol, ibhekisela ekuxhumaneni kwesikhathi sangempela phakathi kwama-endpoints noma abasebenzisi. Lokhu ngokuvamile kuyikholi yezwi kanye/noma yevidiyo.
Umngcele, ibhekisela esixhumini esiphakathi kwamanethiwekhi angenakho ukwethembana okugcwele komunye nomunye.
Isilawuli, ibhekisela ekhonweni le-SBC lokulawula (ukuvumela, ukuphika, ukuguqula, ukuqeda) iseshini ngayinye edlula umngcele.
• Izinzuzo
• Ukuxhumana
Abasebenzi abasebenza ekhaya, noma abasebenzisa iklayenti le-SIP kumakhalekhukhwini abo bangabhalisa nge-SBC ku-IP PBX, ukuze abasebenzisi basebenzise izandiso zabo ezivamile zehhovisi njengokungathi bahleli ehhovisi. I-SBC inikeza i-NAT traversal esezingeni eliphezulu kumafoni akude kanye nokuphepha okuthuthukisiwe kwenethiwekhi yenkampani ngaphandle kwesidingo sokusetha imigudu ye-VPN. Lokhu kuzokwenza ukusetha kube lula kakhulu, ikakhulukazi ngalesi sikhathi esikhethekile.
• Ukuphepha
Ukufihla i-topology yenethiwekhi: Ama-SBC asebenzisa ukuhumusha ikheli lenethiwekhi (i-NAT) ezingeni le-Open Systems Interconnection (OSI) Layer 3 Internet Protocol (IP) kanye nezinga le-OSI Layer 5 SIP ukugcina imininingwane yangaphakathi yenethiwekhi ifihliwe.
I-firewall yesicelo sezwi: Ama-SBC avikela ekuhlaselweni kwe-telephony denial of service (TDoS), ukuhlaselwa kwe-distributed denial of service (DDoS), ukukhwabanisa nokwebiwa kwesevisi, ukulawula ukufinyelela, kanye nokuqapha.
Ukubethela: Ama-SBC abethela isignali kanye nemidiya uma ithrafikhi idlula kumanethiwekhi ebhizinisi kanye ne-inthanethi isebenzisa i-Transport Layer Security (TLS) / Secure Real-Time Transport Protocol (SRTP).
• Ukuqina
Ukulinganisela umthwalo we-trunk ye-IP: I-SBC ixhuma endaweni efanayo phezu kweqembu le-trunk ye-SIP elingaphezu kwelilodwa ukuze ilinganisele imithwalo yocingo ngokulinganayo.
Umzila ohlukile: imizila eminingi eya endaweni efanayo phezu kweqembu le-SIP elingaphezu kwelilodwa ukuze kunqotshwe ukugcwala ngokweqile kanye nokuntuleka kwesevisi.
Ukutholakala okuphezulu: Ukuphindaphinda kwehadiwe okungu-1+1 kuqinisekisa ukuqhubeka kwebhizinisi lakho Ukusebenzisana
• Ukusebenzisana
Ukudlulisa ikhodi phakathi kwama-codec ahlukahlukene kanye naphakathi kwama-bitrate ahlukene (isibonelo, ukudlulisa ikhodi ku-G.729 kunethiwekhi yebhizinisi kuya ku-G.711 kunethiwekhi yomhlinzeki wesevisi ye-SIP)
Ukulungiswa kwe-SIP ngomyalezo we-SIP kanye nokuguqulwa kwekhanda. Ngisho noma usebenzisa amatheminali e-SIP abathengisi abahlukene, ngeke kube nenkinga yokuhambisana ngosizo lwe-SBC.
• Isango le-WebRTC
Ixhuma ama-endpoint e-WebRTC kumadivayisi angewona awe-WebRTC, njengokushaya ucingo kusuka kuklayenti le-WebRTC kuya ocingweni oluxhunywe nge-PSTN
I-CASHLY SBC iyisici esibalulekile esingenakunakwa ekuxazululeni ukusebenza kude kanye nokusebenza ekhaya, iqinisekisa ukuxhumana, ukuphepha kanye nokutholakala, inikeza ithuba lokwakha uhlelo lwe-IP oluzinzile noluphephile ukusiza abasebenzi ukuthi basebenzisane ngisho noma besezindaweni ezahlukene.
Hlala uxhumekile, usebenza ekhaya, ubambisane kahle kakhulu.
