Inkampani futhi ihlinzeka ngosekelo lobuchwepheshe oluphendula ngokushesha kanye namanani ancintisanayo emaphrojekthi amakhulu nawobuningi. Njengomkhiqizi oqhutshwa ukunemba, i-OPA iqinisekisa ukuzinza kwe-firmware nokulula kokuthunyelwa, okuhumushela ezinseleleni ezimbalwa kubahlanganisi nabaphathi bezakhiwo. Lezi zici zenza i-OPA ibe ubambiswano oluthembekile lwesikhathi eside ezinhlanganweni ezazisa ukuthembeka nokukhula okulinganiselwe.
Ingabe izipikha ze-SIP zidinga iseva ezinikezelwe noma isofthiwe ekhethekile?
Izinkulumo eziningi ze-SIP zisebenza ne-IP PBX yakho ekhona noma iseva yokumemezela enomthombo ovulekile, ngakho awudingi ngempela ithuluzi elihlukile elizinikezelwe. Ukusetshenziswa okuningi kusebenzisa isoftware yokumemezela kuserver ejwayelekile ye-Windows noma ye-Linux ephethe ukuhlela, ukuphathwa kwezindawo, nokuqapha kwawo wonke amaspikha. Amaspikha ngokwawo athola iseva ngokuzenzakalelayo esebenzisa i-DHCP nokubhaliswa okujwayelekile kwe-SIP, okwenza ukusethwa kokuqala kube lula kakhulu. Ezikhungweni ezincane, abanye abakhiqizi banikeza nezici zokumemezela ezizimele ezakhelwe ngaphakathi ezisebenza ngaphandle kweseva emaphakathi nhlobo.
Iyini i-multicast futhi kungani ibalulekile ezikhulumini ze-SIP?
I-Multicast iwuhlelo lwenethiwekhi oluthumela umsindo owodwa ngesikhathi esisodwa kuzipikha eziningi ngasikhathi sinye, okubalulekile ekumemezelweni okuhambisanayo ezindaweni ezinkulu. Ngaphandle kwe-multicast, iseva kungenzeka ithumele umsindo ohlukile kusipikha ngasinye, kumoshe umkhawulokudonsa futhi kubangele umehluko wesikhathi phakathi kwezindawo. Izipikha ze-SIP ezisekela i-multicast ziqinisekisa ukuthi insimbi yesikole noma umlayezo wokuphuma ufinyelela kusipikha ngasinye ngomzuzu ofanayo ncamashi. Lesi sici siyingxenye ejwayelekile yezixazululo ze-IP paging ze-OPA futhi sibalulekile ekumemezelweni okuhlobene nokuphepha.
Ngingakwazi ukulawula ivolumu nezindawo ngokukude ngezikhulumi ze-SIP?
Yebo, ukulawula ukude kungenye yezinzuzo ezinkulu zama-SIP speaker uma kuqhathaniswa nezinhlelo ze-analog. Usebenzisa i-dashboard yokulawula emaphakathi noma i-interface yakho ye-IP PBX, ungakwazi ukulungisa ivolumu yanoma yisiphi isipikha ngasinye, uhlanganise izipikha zibe yizigaba ezinengqondo, futhi ushintshe ukwakheka kwezigaba noma nini lapho izidingo zakho zishintsha. Konke lokhu kwenzeka ngesoftware, ngakho akukho sidingo sokukhuphuka ngesitebhisi noma ukushintsha izintambo ngokomzimba ukuze uhlele kabusha izigaba zakho zomsindo. Kwabaqhubi bezitolo eziningi noma amakhampasi, i-dashboard efanayo ingakwazi ukuphatha izipikha ezindaweni zonke kusuka kukhompuyutha eyodwa yokulawula ekude.
Kunzima yini ukuhlanganisa izikhulumi ze-SIP nohlelo olukhona lwefoni ye-VoIP?
Ukuhlanganiswa ngokuvamile kulula kakhulu ngoba izipikha ze-SIP zikhuluma iphrothokholi efanayo namafoni e-VoIP, ngakho i-IP PBX yakho iziphatha njengenye indawo ebhalisiwe. Uma isipikha sibhalisa, ungakwazi ukusithumela ngqo kusukela efonini lasedeskini, i-softphone, noma kusukela kusikhungo sokuphatha se-PBX ngenombolo elula yokudayela noma iqembu elizinikele lokuphesha. I-OPA ihlinzeka ngemibhalo nokusekelwa kwezobuchwepheshe kumapulatifomu amakhulu e-PBX ukuqinisekisa ukusethwa okubushelelezi. Umphumela ukuthi noma iliphi ifoni ohlelweni lwakho liba umbhobho wokuphesha ongasebenziseka ngaphandle kwezingxenye ezengeziwe zokusebenza.
Iluphi uhlobo lwewaranti nokusekelwa okunikezwa yi-OPA ezikhulumini zayo ze-SIP?
I-OPA imele imikhiqizo yayo yezipikha ze-SIP ngewarranti ebanzi kanye nokusekelwa kwezobuchwepheshe okuphendula ngokushesha, okuhloswe ukunikeza abahlanganisi nabawashi bezindawo ukuthula kwengqondo. Ithimba lokusekelwa lenkampani lisiza ngokucushwa, ukuxazulula izinkinga, kanye nokuhlanganiswa namaplathifomu ahlukahlukene e-IP PBX, futhi amakhasimende amaningi athola usizo olukhethekile lwamaphrojekthi amakhulu. Izibuyekezo ze-Firmware ziyanikezwa ukuze kuqinisekiswe ukuthi amadivayisi ahlala ehambisana namazinga nezici zenethiwekhi eziguqukayo. Mayelana nemigomo ethile yewarranti nezinketho zokusekelwa, kungcono ukuthintana ngekhasi lokuxhumana noma lokwenza ngendlela yakho le-OPA, unikeze imininingwane ngephrojekthi yakho.
