Woyang'anira Malire a Session - Gawo Lofunika Kwambiri Pakugwira Ntchito Kutali
• Mbiri
Panthawi ya mliri wa COVID-19, malangizo a "kutalikirana pakati pa anthu" amakakamiza antchito ambiri amakampani ndi mabungwe kuti azigwira ntchito kunyumba (WFH). Chifukwa cha ukadaulo waposachedwa, tsopano n'kosavuta kuti anthu azigwira ntchito kulikonse kunja kwa ofesi yachikhalidwe. Mwachionekere, sikuti ndi chifukwa cha pano pokha, komanso mtsogolo, chifukwa makampani ambiri makamaka makampani apaintaneti amalola antchito kugwira ntchito kunyumba ndikugwira ntchito mosavuta. Kodi mungagwirizanitse bwanji wina ndi mnzake kuchokera kulikonse m'njira yokhazikika, yotetezeka komanso yothandiza?
Mavuto
Dongosolo la IP telephony ndi njira imodzi yofunika kwambiri yogwirira ntchito limodzi ndi maofesi akutali kapena ogwiritsa ntchito kunyumba. Komabe, ndi kulumikizana kwa intaneti, pamabwera mavuto angapo ofunikira achitetezo - chachikulu ndikuteteza ma SIP scanners omwe amayesa kulowa m'maukonde a makasitomala.
Monga momwe ogulitsa ambiri a IP telephony system adazindikira, ma SIP scanner amatha kupeza ndikuyamba kuukira ma IP-PBX olumikizidwa pa intaneti mkati mwa ola limodzi kuchokera pamene atsegulidwa. Oyambitsidwa ndi achinyengo apadziko lonse lapansi, ma SIP scanner nthawi zonse amafunafuna ma seva a IP-PBX osatetezedwa bwino omwe angawagwiritse ntchito poyambitsa mafoni achinyengo. Cholinga chawo ndikugwiritsa ntchito IP-PBX ya wozunzidwayo kuyambitsa mafoni ku manambala apamwamba a foni m'maiko omwe alibe malamulo. Ndikofunikira kwambiri kuteteza ku SIP scanner ndi maulalo ena.
Komanso, poyang'anizana ndi zovuta za ma netiweki osiyanasiyana komanso zida zambiri za SIP kuchokera kwa ogulitsa osiyanasiyana, vuto la kulumikizana nthawi zonse limakhala lovuta. Ndikofunikira kwambiri kukhala pa intaneti ndikuwonetsetsa kuti ogwiritsa ntchito mafoni akutali alumikizana bwino.
CASHLY session border controller (SBC) ndi chida chabwino kwambiri chogwiritsira ntchito pa zosowa izi.
• Kodi Wolamulira wa Malire a Session (SBC) ndi chiyani?
Oyang'anira malire a Session border (SBCs) ali m'mphepete mwa netiweki ya bizinesi ndipo amapereka kulumikizana kotetezeka kwa mawu ndi makanema kwa opereka chithandizo cha Session Initiation Protocol (SIP), ogwiritsa ntchito m'maofesi a nthambi akutali, ogwira ntchito kunyumba/ogwira ntchito kutali, ndi opereka chithandizo cha united communications as a service (UCaaS).
Gawo, kuchokera ku Session Initiation Protocol, imatanthauza kulumikizana kwa nthawi yeniyeni pakati pa ma endpoints kapena ogwiritsa ntchito. Izi nthawi zambiri zimakhala kuyimba kwa mawu ndi/kapena kanema.
Malire, imatanthauza kulumikizana pakati pa ma network omwe sakhulupirirana kwathunthu.
Wowongolera, imatanthauza kuthekera kwa SBC kulamulira (kulola, kukana, kusintha, kuthetsa) gawo lililonse lomwe limadutsa malire.
• Ubwino
• Kulumikizana
Ogwira ntchito akugwira ntchito kunyumba, kapena kugwiritsa ntchito kasitomala wa SIP pafoni yawo yam'manja akhoza kulembetsa kudzera mu SBC kupita ku IP PBX, kuti ogwiritsa ntchito athe kugwiritsa ntchito zowonjezera zawo zachizolowezi zaofesi ngati kuti akukhala muofesi. SBC ikupereka njira yolumikizirana ya NAT yakutali pama foni akutali komanso chitetezo chowonjezereka pa netiweki yamakampani popanda kufunikira kukhazikitsa ma tunnel a VPN. Izi zipangitsa kuti kukhazikitsa kukhale kosavuta, makamaka panthawi yapaderayi.
• Chitetezo
Kubisa topology ya netiweki: Ma SBC amagwiritsa ntchito kumasulira ma adilesi a netiweki (NAT) pamlingo wa Open Systems Interconnection (OSI) Layer 3 Internet Protocol (IP) ndi mulingo wa OSI Layer 5 SIP kuti asunge tsatanetsatane wamkati mwa netiweki.
Chiwotchi choteteza mawu: Ma SBC amateteza ku ziwopsezo za telephony denial of service (TDoS), ziwopsezo za kukana kugawa kwa service (DDoS), chinyengo ndi kuba kwa service, kuwongolera mwayi wolowa, ndi kuyang'anira.
Kubisa: Ma SBC amabisa chizindikiro ndi zoulutsira nkhani ngati magalimoto akuyenda m'maukonde amakampani ndi intaneti pogwiritsa ntchito Transport Layer Security (TLS) / Secure Real-Time Transport Protocol (SRTP).
• Kulimba mtima
Kulinganiza katundu wa trunk ya IP: SBC imalumikizana ndi malo omwewo pa gulu la trunk ya SIP loposa limodzi kuti igwirizanitse katundu woyitanidwa mofanana.
Njira ina yolumikizirana: njira zingapo zopita kumalo amodzi pa gulu la SIP loposa limodzi kuti athetse kuchuluka kwa magalimoto ndi kusowa kwa ntchito.
Kupezeka kwakukulu: Kuchuluka kwa zida za 1 + 1 kumatsimikizira kupitiliza kwa bizinesi yanu. Kugwirizana
• Kugwirizana
Kusintha ma codec pakati pa ma codec osiyanasiyana ndi ma bitrate osiyanasiyana (monga, kusintha ma codec G.729 mu netiweki yamakampani kupita ku G.711 pa netiweki ya opereka chithandizo cha SIP)
Kusintha kwa SIP kudzera mu uthenga wa SIP ndi kusintha mutu. Ngakhale mukugwiritsa ntchito ma SIP terminals a ogulitsa osiyanasiyana, sipadzakhala vuto logwirizana ndi chithandizo cha SBC.
• Chipata cha WebRTC
Imalumikiza ma endpoint a WebRTC ku zida zomwe si za WebRTC, monga kuyimba kuchokera kwa kasitomala wa WebRTC kupita ku foni yolumikizidwa kudzera pa PSTN
CASHLY SBC ndi gawo lofunikira kwambiri lomwe silinganyalanyazidwe pogwira ntchito patali komanso pogwira ntchito kunyumba, limaonetsetsa kuti kulumikizana, chitetezo ndi kupezeka, limapereka mwayi womanga njira yokhazikika komanso yotetezeka ya IP telephony kuti ithandize ogwira ntchito kugwira ntchito limodzi ngakhale ali m'malo osiyanasiyana.
Khalani olumikizana, kugwira ntchito kunyumba, gwirani ntchito limodzi bwino.
