Ku bigo byo guhamagara - Huza abakozi bawe ba kure
• Incamake
Mu gihe cy'icyorezo cya COVID-19, ntabwo byoroshye ko ibigo bishinzwe guhamagara bikomeza imirimo isanzwe. Abakozi baho bakunze gukwirakwira mu turere dutandukanye kuko abenshi muri bo bagomba gukorera mu rugo (WFH). Ikoranabuhanga rya VoIP rigufasha gutsinda iyi mbogamizi, gutanga serivisi zikomeye nk'uko bisanzwe no kugumana izina ry'ikigo cyawe. Dore bimwe mu bikorwa bishobora kugufasha.
• Guhamagara binjira
Nta gushidikanya ko Softphone (ishingiye kuri SIP) ari igikoresho cy'ingenzi cyane ku bikoresho byawe byo kuri interineti. Ugereranyije n'ubundi buryo, gushyiramo porogaramu kuri mudasobwa biroroshye, kandi abatekinisiye bashobora kugufasha muri iki gikorwa bakoresheje ibikoresho byo kuri interineti byo kuri interineti. Tegura ubuyobozi bwo gushyiraho ibikoresho byo kuri interineti ndetse no kwihangana.
Telefoni za IP zo kuri mudasobwa nazo zishobora koherezwa aho abashinzwe serivisi baherereye, ariko menya neza ko imiterere yazo yamaze gukorwa kuri izi telefoni kuko abashinzwe serivisi si abanyamwuga mu bya tekiniki. Ubu seriveri nkuru za SIP cyangwa IP PBXs zishyigikira uburyo bwo gutanga amakuru bwikora, bishobora koroshya ibintu kurusha mbere.
Izi terefone zoroshye cyangwa telefoni za IP ubusanzwe zishobora kwandikwa nk'inyongera za SIP ziri kure kuri seriveri yawe nkuru ya SIP mu cyicaro gikuru cya call center binyuze kuri VPN cyangwa DDNS (Dynamic Domain Name System). Abashinzwe serivisi bashobora kugumana inyongera zabo z'umwimerere n'uburyo bakoresha. Hagati aho, hari igenamiterere rike rigomba gukorwa kuri firewall/router yawe nko kohereza port n'ibindi, ibyo bikaba byateza ibibazo by'umutekano, ikibazo ntikishobora kwirengagizwa.
Kugira ngo byorohereze abantu kwinjira kuri telefoni yoroshye iri kure na telefoni ya IP, Session border controller (SBC) ni igice cy'ingenzi cy'iyi sisitemu, igomba gushyirwa ku nkengero z'umuyoboro w'ikigo cy'itumanaho. Iyo SBC ishyizwe ku isoko, abantu bose basura itumanaho rya VoIP (haba mu buryo bw'amajwi n'itangazamakuru) bashobora kuva kuri telefoni zoroshye cyangwa telefoni za IP binyuze kuri interineti rusange bakajya kuri SBC, ibi bikaba bituma abantu bose basura itumanaho rya VoIP binjira cyangwa bisohoka bagenzurwa neza n'ikigo cy'itumanaho.
Imirimo y'ingenzi ikorwa na SBC irimo
Gucunga imipaka ya SIP: SBC ikora nka seriveri ya proxy ya UC/IPPBXs, ubutumwa bwose bujyanye na SIP bugomba kwemerwa no koherezwa na SBC. Urugero, mu gihe softphone igerageza kwiyandikisha kuri IPPBX iri kure, izina rya IP/domaine ritemewe cyangwa konti ya SIP bishobora kuba biri mu mutwe wa SIP, bityo ubusabe bwo kwiyandikisha bwa SIP ntibuzoherezwa kuri IPPBX kandi bwongereho IP/domaine itemewe ku rutonde rw'ababura.
Uburyo bwo kunyura muri NAT, kugira ngo hakorwe igenamiterere hagati y’ahantu hihariye ho gushyira aderesi za IP na interineti rusange.
Ubwiza bwa serivisi, harimo gushyira imbere urujya n'uruza rw'abagenda hashingiwe ku miterere ya ToS/DSCP hamwe n'imicungire ya bandwidth. SBC QoS ni ubushobozi bwo gushyira imbere, kugabanya no kunoza ibihe mu gihe nyacyo.
Nanone, SBC itanga ibintu bitandukanye kugira ngo irinde umutekano nko kurinda DoS/DDoS, guhisha topology, SIP TLS / SRTP encryption nibindi, irinda call centers ibitero. Byongeye kandi, SBC itanga ubushobozi bwo gukorana na SIP, transcoding no gukoresha itangazamakuru mu kongera uburyo bwo guhuza sisitemu ya call centre.
Ku kigo cy’itumanaho kidashaka gukoresha SBC, ubundi buryo ni ukwishingikiriza ku mikoranire ya VPN hagati y’ikigo cy’itumanaho cyo mu rugo n’ikigo cy’itumanaho cyo kure. Ubu buryo bugabanya ubushobozi bwa seriveri ya VPN, ariko bushobora kuba buhagije mu bihe bimwe na bimwe; mu gihe seriveri ya VPN ikora akazi k’umutekano no gukoresha NAT, ntiyemerera gushyira imbere urujya n’uruza rwa VoIP kandi akenshi birahenda kuyicunga.
• Guhamagara hanze
Ku bijyanye no guhamagara hanze, koresha gusa telefoni zigendanwa z'abakozi. Shyiraho telefoni igendanwa y'abakozi nk'inyongera. Iyo umukozi ahamagaye hanze akoresheje softphone, seriveri ya SIP izamenya ko iyi ari inyongera ya telefoni igendanwa, hanyuma ibanje guhamagara nimero ya telefoni igendanwa binyuze kuri VoIP media gateway ihujwe na PSTN. Nyuma yuko telefoni igendanwa y'abakozi irangiye, seriveri ya SIP ihita itangiza guhamagara umukiriya. Muri ubu buryo, ubunararibonye bw'umukiriya ni bumwe. Iki gisubizo gikeneye ibikoresho bibiri bya PSTN aho ibigo bihamagara hanze akenshi biba bifite imyiteguro ihagije.
• Huza n'abatanga serivisi
SBC ifite uburyo bwo guhamagara bugezweho, ishobora guhuza no gucunga abatanga serivisi nyinshi za SIP Trunk binjira n'ibisohoka. Byongeye kandi, hashobora gushyirwaho SBC ebyiri (1+1 redundancy) kugira ngo haboneke amakuru menshi.
Kugira ngo uhuze na PSTN, E1 VoIP gateways ni amahitamo meza. Irembo rya E1 rigizwe n'abantu benshi nka CASHLY MTG series Digital VoIP gateways rifite E1 zigera kuri 63, SS7 kandi rifite ibiciro bishimishije cyane, ritanga ubwishingizi buhagije bw'ibikoresho byo mu bwoko bwa trunk iyo hari urujya n'uruza rw'abantu benshi, kugira ngo ritange serivisi zitari nziza ku bakiriya ba centre.
Ibigo byo guhamagara bikorera mu rugo, cyangwa abakozi bakorera kure, byihutishwa gukoresha ikoranabuhanga rigezweho kugira ngo bikomeze kumererwa neza, atari muri iki gihe cyihariye gusa. Ku bigo bihamagara bitanga serivisi ku bakiriya mu duce twinshi tw’amasaha, ibigo bihamagara kure bishobora gutanga ubwishingizi bwuzuye bitabaye ngombwa ko abakozi bashyirwa mu myanya itandukanye. Rero, itegure ubu!
