He aha te pūnaha whakawhitiwhiti SIP, ā, me pēhea te mahi?

He aha te hiranga o ngā pūnaha whakawhitiwhiti SIP mō te urunga arumoni

Ko te Kawa Tīmatanga Wāhanga (SIP), i tautuhia e te Rōpū Mahi Hangarau Ipurangi (IETF) i raro i te RFC 3261, kua tino whakarerekē i ngā whakawhitiwhitinga kōrero a te umanga. Ina whakamahia ki te whakahaere urunga ā-tinana, ka mahi te pūnaha waea SIP hei pūwāhi whakahohea-IP i runga i te whatunga Kawa Reo i runga i te Ipurangi (VoIP). Kāore i rite ki ngā waea anaro tawhito e whakawhirinaki ana ki ngā waea motuhake, ka whakamahia e ngā waea SIP te hanganga Ethernet paerewa hei tuku tohu oro, ataata, me te whakahaere. Mā tēnei paerewa ka taea e ngā whare umanga te whakakotahi i ā rātou tūāpapa haumarutanga ā-tinana me ngā whakawhitiwhitinga kōrero kotahi (UC) ki roto i te hoahoa kotahi, honohono.

Mā te whakatinanatanga o ngā taputapu e hangai ana ki te SIP ka whakakapia ngā pūnaha urunga motuhake ki ngā taputapu whatunga taketake e kaha ana ki te ara uaua, te tuku waea ā-wāhanga, me te rere pāpāho whakamāramatanga teitei. Mā te whakamahi i ngā tūmau Private Branch Exchange (PBX) e whakamahia ana mō te waea a te kamupene, ka taea e ngā whakahaere te whakakore i ngā hanganga koretake. He mea tino nui tēnei huihuinga mō te urunga arumoni, ko te manatoko tere o ngā manuhiri me te whakaurunga pai ki ngā pūnaha IT o nāianei e tohu ana i te whai huatanga o te mahi me te haumarutanga o te whare.

Te Whakawhitiwhiti Kōrero me te Mana Whakauru Manuhiri

Kei te pūtake o te pūnaha waea whakawhitiwhiti SIP te kaha ki te whakahaere i te whakawhitiwhiti kōrero ā-rua, ā-wā tūturu i waenga i te manuhiri i te pūwāhi tomokanga me te kaiwhakahaere kei hea i te ao. Ina pēhi te manuhiri i te pātene waea i runga i te waea whakawhitiwhiti, ka mahi te taputapu hei Kaihoko Kaiwhakamahi SIP (UA). Ka whakaputahia he tono SIP INVITE, ka tukuna e te PBX ki tētahi pūwāhi kua tohua—pērā i te waea IP a te kaiwhiwhi manuhiri, he papatohu pokapū whakahaere haumarutanga (SOC), he taupānga pūkoro rānei.

Mā tēnei ara IP ka taea te whakahaere i ngā rerengamahi whakaurunga matatau. Hei tauira, ki te kore e whakautua e te tēpu whiwhinga tuatahi i roto i tētahi paepae kua tautuhia (hei tauira, 15 hēkona), ka taea e te kawa SIP te tuku aunoa i te waea ki tētahi rōpū haumarutanga tuarua, ki tētahi whare aroturuki i waho o te papaanga rānei. Hei whakarite i te kōrerorero maori, kore e mutu, kua hangaia ngā waea SIP taumata-hinonga hei pupuri i te roanga oro mai i te pito ki te pito i raro i te 150 mirihekona. Kia manatokohia te tuakiri o te manuhiri, ka taea e te kaiwhakahaere te tuku i tētahi tohu Auautanga Maha-Oro-Rua (DTMF)—e whirihorahia ana mā te RFC 2833—ka riro i te waea ka whakamaoritia hei whakahau hei whakaoho i tētahi whakawhiti i runga i te papa, kia huakina ai te tatau.

Ngā Painga Whakahaere me te Haumarutanga

He nui ngā painga whakahaere me te haumarutanga o te nekehanga ki ngā waea whakawhitiwhiti SIP, e ahu mai ana i te nuinga o te wā i te whakaurunga me te whakahaere mamao. Nā te mea kei runga i te whatunga IP umanga ēnei taputapu, ka taea e ngā kaiwhakahaere hangarau mōhiohio me te haumarutanga te whakarato, te aroturuki, me te whakahou i ngā rau o ngā waeine waea whakawhitiwhiti mai i te atanga kotahi. Mā tēnei whakahaere pokapū ka whakaitihia te utu tiaki, ā, ka taea te aroturuki hauora matatau mā te Simple Network Management Protocol (SNMP) me te whakatūpato aunoa.

I te taha pūtea, ka whakamahia e ngā waea whakawhitiwhiti SIP ngā hanganga whatunga rohe (LAN) o nāianei. Mā te whakamahi i te paerewa Power over Ethernet (PoE) IEEE 802.3af, ka tukuna e te taura Cat5e, Cat6 rānei te hononga raraunga me te 15.4 watts o te hiko iahiko tika ki te pito mutunga. Mā tēnei ka kore e hiahiatia he rere hiko ngaohiko teitei motuhake ki ia tatau, ka whakaitihia ngā utu taura tāutanga tae atu ki te 40% i roto i ngā kaupapa hanga hou. Mai i te tirohanga haumarutanga, mā te whakauru i ngā waea whakawhitiwhiti SIP me ngā anga haumarutanga whānui ka taea te tuhi aunoa i ngā aituā. Ko ia nganatanga waea, te roa o te hononga, me te huihuinga iriti tatau ka tuhia ki roto i ngā rekoata taipitopito waea PBX (CDR), ka whakarato i tētahi ara tika, ka taea te tirotiro i ngā huihuinga urunga.

Ngā mea kei roto i te pūnaha SIP Intercom

Ko ngā taputapu taha o tēnei pūnaha ko ngā intercom tatau SIP me ngā intercom ataata kua tāutahia ki ngā pūwāhi tomo ā-tinana. Me hono ēnei waeine i te āputa i waenga i ngā wāhanga hiko tairongo me ngā taiao o waho kino.Ngā intercom SIP o waho o te taumata ahumahiKo te nuinga o te wā he IP65, he teitei ake rānei te whakatauranga mō te tiaki i te puehu me te urunga mai o te wai, ā, mai i te IK08 ki te IK10 te ātete ki te pānga miihini me te mahi kino. I roto i te anga, kei roto i ēnei taputapu ngā tukatuka tohu mamati kua whakauruhia (DSP) hei whakahaere i te whakakorenga oro me te whakaiti i te haruru papamuri.

Ka tāpirihia e ngā waea whakawhitiwhiti SIP e whakahohea ana e te ataata he paparanga manatoko tirohanga nui. He whānui ngā karāhe o ēnei waeine, e tuku ana i te whānuitanga tirohanga mai i te 120 ki te 170 nekehanga hei hopu i ngā manuhiri ahakoa te teitei, te tūnga rānei. Ka whakaratohia e ngā pūoko whakaahua whakamāramatanga teitei te taumira 1080p, mā te whakamahi i ngā rauropi kōpeketanga ataata H.264, H.265 rānei. Mā tēnei kōpeketanga matatau ka taea te tuku i ngā awa ataata kounga teitei ki te pito whakautu me te kore e whakakī i te whānui o te whatunga ā-rohe, e 2 ki te 4 Mbps noa iho te tere e hiahiatia ana mō ia waea ataata hohe.

Ngā Wāhanga Pūmārō me te Pūmanawa e Hiahiatia ana

Haunga te waeine whakawhitiwhiti kōrero ā-tinana, ka whakawhirinaki te pūnaha ki ētahi wāhanga taputapu me ngā pūmanawa o muri. Ko te miihini ara matua ko te IP-PBX, ka taea te manaaki i runga i te papaanga, te whakamāori i roto i te pokapū raraunga umanga, te tuku rānei hei tūāpapa Unified Communications as a Service (UCaaS) e ahu mai ana i te Kapua. Ko te PBX te kaitiaki i te rēhita SIP me te whakahaere i te mahere arorau o ngā toronga ki ngā wāhitau IP ā-tinana.

Ko ngā pana PoE te pūtake o te hononga me te mana ki te whatunga. Ahakoa he rawaka te 802.3af (15.4W) paerewa mō te nuinga o ngā intercom oro me ngā intercom ataata taketake, ko ngā waeine e whakamahia ana i ngā āhuarangi tino makariri e hiahia ana ki ngā wāhanga whakamahana ā-roto e hiahia ana ki te PoE+ (IEEE 802.3at), e tuku ana ki te 30W mō ia tauranga. Hei whakamutunga, ko te wāhanga urunga ā-tinana e hiahia ana ki ngā taputapu tatau hiko—pērā i ngā raka aukume, ngā patu hiko rānei—e hono tika ana ki ngā whakawhiti o roto o te intercom. Ko ēnei whakawhiti he mea whakatau kia whakawhiti i ngā kawenga DC 12V, 24V rānei, hei hanga i te hononga whakamutunga i roto i te mekameka mai i te whakahau SIP mamati ki te tukunga tatau ā-tinana.

Te Mahi a ngā Pūnaha Whakawhitiwhiti SIP

Ko te whakahaere o te pūnaha waea whakawhitiwhiti SIP e whakawhirinaki ana ki tētahi wehenga pakari i waenga i te papa whakahaere—e whakahaere ana i te whakatūnga waea, te whakarerekētanga, me te wawahi—me te papa raraunga, e kawe ana i ngā awa oro me ngā ataata. Mā tēnei hoahoa wehe ka taea e te SIP te tino ngāwari, ka taea ai te whiriwhiri i ngā tawhā whakawhitiwhiti kōrero i waenga i ngā taputapu he rerekē rawa ngā āheinga taputapu.

Rēhitatanga SIP, Ara Waea, me te Pāpāho RTP

Ka tīmata te huringa ora o tētahi wātū waea whakawhitiwhiti me te rēhitatanga SIP. Kia tīmatahia, ka tukuna e te waea whakawhitiwhiti he tono SIP REGISTER ki te PBX, e whakamana ana i a ia anō mā te whakamahi i te manatoko MD5, SHA-256 rānei, ā, ka pānuitia tōna wāhitau IP o nāianei. Kia rēhitatia, kua rite te waea whakawhitiwhiti ki te tīmata waea. Ina pēhia te pātene waea, ka tukuna e te waeine he karere SIP INVITE kei roto he utunga Kawa Whakaahuatanga Wātū (SDP). Ka whakamāramahia e te SDP ngā āheinga pāpāho o te waea whakawhitiwhiti, tae atu ki ngā kōtēke oro e tautokona ana (pēnei i a G.711 mō te reo paerewa, G.722 mō te oro HD whānui, Opus rānei mō ngā āhuatanga whatunga rerekē) me ngā kōtēke ataata.

Ka tukatukahia e te PBX tēnei PŌHIRITANGA, ka tukuna ki te toronga ūnga. Kia whakaaetia te waea e te kaiwhiwhi, ka tukuna he karere 200 OK ki te intercom, ā, ka whai ake ko te ACK hei whakaoti i te rūrū ringa. I tēnei wā, ka wehe te tohu SIP ki te taha, ā, ka tangohia e te Real-time Transport Protocol (RTP) te papa raraunga. Ka whakatūhia e te RTP he awa pāpāho hoa-ki-hoa, he awa pāpāho tūmau-tuku rānei i waenganui i te intercom me te taputapu whakautu, kia tere ai te tuku o ngā mōkihi oro me te ataata me te iti o te parenga.

Ngā Whakaritenga Whatunga me te Haumarutanga Ipurangi

Nā te mea he taputapu whatunga ngā waea whakawhitiwhiti SIP kei waho o te whare, ka whakauruhia e rātou he whakaritenga motuhake mō te haumarutanga tukutuku me te āhua whatunga. Hei ārai i te urunga whatunga kore whakamanahia mā te taura Ethernet o waho e kitea ana, ka tino wehea e ngā kaihoahoa haumarutanga ngā waea whakawhitiwhiti mā te whakamahi i ngā Whatunga Rohe Mariko (VLAN). Hei tāpiri, mā te Mana Uru Whatunga (NAC) e hangai ana ki te tauranga e whakamahi ana i te paerewa IEEE 802.1X ka whakarite mēnā ka momotuhia e te tangata kino te waea whakawhitiwhiti ka hono i te pona, ka whakakorea tonutia te tuku raraunga e te tauranga whakawhiti.

Hei tiaki i ngā kawenga whakawhitiwhiti kōrero, ka whakatinanahia e ngā whakatinanatanga waea whakawhitiwhiti SIP hou te whakamunatanga i runga i ngā papa whakahaere me ngā papa raraunga. Ka whakamunatia te tohu SIP mā te whakamahi i te Transport Layer Security (TLS 1.2, 1.3 rānei), ka hangaia he hononga SIPS (SIP Secure) e ārai ana i te whakarongo puku ki ngā raraunga ara waea me ngā waehere iriti DTMF. Ka tiakina ngātahitia ngā awa pāpāho RTP mā te whakamahi i te Secure Real-time Transport Protocol (SRTP), mā te whakamahi i ngā tohu AES-128, AES-256 rānei hei ārai i te hopu, te whakarerekē rānei i ngā whāngai oro me te ataata. He mea whakahau hoki ngā ture Kounga Ratonga (QoS); me tohu e ngā kaiwhakahaere whatunga te waka reo waea whakawhitiwhiti ki te uara Differentiated Services Code Point (DSCP) 46 (Expedited Forwarding) hei whakatairanga i tēnei i runga ake i te waka raraunga paerewa.

Te Hinga, Te Waeatanga Āwhati, me ngā Rangitaki Aromatawai

I roto i ngā mahi arumoni mengā taiao ahumahi, kāore e taea te whiriwhiri i te nui o te wātea. Ka tutuki i ngā pūnaha waea whakawhitiwhiti SIP te manawanui mā roto i ngā whirihoranga tūmau SIP taurite. Ka taea te whakarite i ngā waea whakawhitiwhiti me ngā wāhitau IP PBX tuatahi me tuarua. Ki te kore te tūmau tuatahi e whakautu ki te ping SIP OPTIONS keep-alive, ka kore te waea whakawhitiwhiti e tukuna ki te tūmau tuarua, ā, i te nuinga o te wā ka whakahaerehia te pana i raro i te 5 hēkona hei whakarite i te mahi whakahaere urunga tonu.

Kua whakauruhia hoki ngā āhuatanga waea ohorere ki roto i ngā rerengamahi SIP. Ka taea te whakarite i ngā waea kua tohua hei pūwāhi āwhina ohorere kia karo i te whiwhinga ā-rohe me te tuku waea tika ki ngā kaituku waea ohorere o waho (hei tauira, ngā PSAP) mā te hononga SIP. Hei whakatutuki i ngā whakaritenga arotake ture me te haumarutanga, ka tuhia ngā tauwhitinga SIP katoa me ngā huihuinga pūnaha. Ka panaia e ngā waea ēnei rangitaki ki ngā tūmau pokapū mā te whakamahi i te kawa Syslog. Ka hopukina e tēnei ara arotake ngā tātaritanga nui, tae atu ki ngā nganatanga rēhita SIP kore i angitu, ngā waehere hapa SIP 4xx/5xx, me ngā tohu wā tika o ngā whakawhiti iriti tatau DTMF, e āwhina ana i te tātaritanga tātaritanga whai muri i te aituā.

Te Whakataurite i ngā Pūnaha Whakawhitiwhiti SIP ki ngā Huarahi Rerekē

He maha ngā huarahi hangarau e tukuna ana e te mākete haumarutanga ā-tinana ki te whakawhitiwhiti kōrero me te whakahaere whakaurunga manuhiri. Ahakoa kei te whakahaerehia tonutia ngā pūnaha tawhito puta noa i ngā whare tawhito, kei te kitea he panonitanga nui ki ngā otinga IP paerewa-tuwhera te umanga. Ko te whakataurite i ngā pūnaha waea SIP me ngā momo IP ā-anaro me ā-motuhake e whakaatu ana i ngā painga me ngā herenga hoahoa o ia huarahi.

SIP vs. Ngā Whakawhiti IP Analog me te IP Motuhake

Ko ngā waea whakawhitiwhiti reo-anaro te hoahoa tawhito rawa atu, tino pakari hoki i roto i te ao whakahaere urunga. Ka whakawhirinaki rātou ki ngā taura parahi motuhake, e rua, e whā rānei ngā waea, e hono tika ana i te teihana tatau ki tētahi teihana whakautu matua. He nui ngā herenga tawhiti o tēnei āhuaranga waea-ki-te-ira; ko te kounga oro reo-anaro ka tīmata te heke nui atu i te 300 mita nā te ātete hiko me te whakaiti tohu. Hei tāpiri, kāore e taea e ngā pūnaha reo-anaro te whakauru ngāwari ki ngā whatunga IT hou, ka wehea te haumarutanga ā-tinana mai i ngā whakawhitiwhitinga a te kamupene.

Ka whakatauhia e ngā waea whakawhitiwhiti IP motuhake ngā take taura me te tawhiti o te anaro mā te whakamahi i te Ethernet (he rohe taketake 100-mita engari ka taea te toro atu mutunga kore mā te muka whatu me ngā pana whatunga). Heoi, ka whakamahia e rātou ngā kawa whakawhitiwhiti katia, motuhake ki te kaihoko, kaua ki te paerewa SIP tuwhera. Mā tēnei ka maukati te hinonga ki te hoko teihana whakautu, raihana pūmanawa, me ngā whakapainga taputapu mai i te kaihanga kotahi anake. He rerekē, ka whakaratohia e ngā waea whakawhitiwhiti SIP te kore aro ki te taputapu. Ka taea e te hinonga te hono i tētahiHe waea SIP mai i te kaihanga kotahime te Cisco, Avaya, Asterisk PBX rānei, ā, ka whakautu waea i runga i ngā waea ngohengohe SIP paerewa, ka karo katoa i te raka a te kaihoko.

Ngā Waea Whakawhiti SIP me te Cloud PBX me ngā Pūhara Whakahaere Uru

Ka kitea te rerekētanga tuturu o ngā intercom SIP ina whakauruhia ki ngā pūnaha Cloud PBX hou me ngā pūnaha Mana Urunga hinonga.Ngā tūāpapa PBX kapua(pērā i a Zoom Phone, Microsoft Teams mā te Direct Routing, RingCentral rānei) ka taea te whakahaere i ngā intercom SIP me te kore he hanganga tūmau kei roto i te papa. Ka taea e te manuhiri e pēhi ana i te pātene intercom te waea tonu i te taupānga waea atamai a te kaitiaki haumarutanga mā te whatunga 5G, ka taea ai te whakahaere i te urunga ā-ao.

I te wā kotahi, ka mahi ngā waea whakawhitiwhiti SIP hei taputapu taha mō ngā pūnaha whakahaere urunga ā-tinana whānui (PACS). Kei roto i ngā waea whakawhitiwhiti SIP matatau ngā atanga Wiegand, Open Supervised Device Protocol rānei (OSDP). Mā tēnei ka taea e te waea whakawhitiwhiti te pupuri i tētahi kaipānui kāri RFID whakauru, i tētahi matawai koiora rānei. Mā te tautoko i te OSDP Secure Channel (e whakamahi ana i te whakamunatanga AES-128), ka tukuna marietia e te waea whakawhitiwhiti SIP ngā raraunga tohu ki te tūmau whakahaere urunga matua i te wā kotahi e whakahaere ana i te wā oro/ataata SIP. Hei tāpiri, ka tautokohia e ngā waeine SIP hou ngā RESTful API me ngā Webhooks, e āhei ai ngā kaiwhakawhanake ki te whakahohe i ngā mahi waea whakawhitiwhiti aunoa i runga i ngā kaupapa haumarutanga uaua, pērā i te raka i tētahi puni mā te whakahau pūmanawa kotahi.

Me pēhea te whiriwhiri, te whakatinana, me te pupuri i tētahi pūnaha whakawhitiwhiti SIP

Ko te whakatinanatanga angitu o tētahi pūnaha waea whakawhitiwhiti SIP me whai huarahi hangarau hanganga e hono ana i te āputa i waenga i ngā whakaurunga haumarutanga ā-tinana me te whakahaere whatunga IT. Nā te mea kei waenganui i ngā arai ā-tinana me ngā pona whatunga arorau ēnei taputapu, me whakamaheretia marietia te hoko me te whakatinanatanga kia mau ai te pono me te tutuki i ngā whakaritenga mō te wā roa.

Te Rangahau Pae me ngā Whakaritenga Pūnaha

Ka tīmata te huringa whakatinanatanga me te arotakenga whānui o te papaanga. Ko ngā taiao whakairinga ā-tinana e whakatau ana i ngā whakaritenga taputapu e hiahiatia ana. Hei tauira, me arotake te oro o tētahi intercom kua tāutahia ki te taha o tētahi rori pukumahi, ngā mīhini ahumahi rānei; ki te neke atu i te 75 decibels (dB) te haruru o te taiao, me whai te intercom SIP kua tīpakohia i te whakakore haruru hohe me te hopuoro nui-whakanui hei whakarite kia mārama te tuku oro. Waihoki, ko ngā intercom ataata e anga atu ana ki te rā tika me whai pūoko whakaahua matatau kua rite ki ngā āheinga Whānui Hihiri (WDR) o te 120dB neke atu rānei hei ārai i ngā manuhiri kei puta mai hei atarangi pouri i te papamuri kanapa.

Me mahere hoki e ngā whakaritenga pūnaha te āhua o te whatunga. Me whakarite e ngā kaihangarau whatunga ngā wāhitau IP tūmau, me whirihora rānei i ngā rahui DHCP mō ia pūwāhi waea whakawhitiwhiti. Me tatau te tahua mana PoE puta noa i ngā pana whatunga katoa kia nui ai te mana e wātea ana, inā koa mēnā kei roto i te whakatinanatanga ngā waeine whaiaronga SIP maha-pātene, ngā waea whakawhitiwhiti rānei me ngā wāhanga whakamahana ā-roto e kukume taumaha ana mō ngā āhuarangi i raro i te kore.

Te Whakamahere Whakatutukitanga me te Haumarutanga

He wāhanga nui o te tukanga whakamahere te whakatutukitanga i ngā ture hanga whare ā-rohe me ngā ture tūmataitinga raraunga. I te Hononga o Amerika, me ū ngā tāutanga waea waea ki te Ture mō ngā Hauātanga o Amerika (ADA). E whakahau ana tēnei i ngā tawhā whakapuru tinana tino pakari, pērā i te whakarite kia kaua e neke ake i te 48 inihi te teitei o ngā wāhanga ka taea te whakahaere (te pātene karanga) i te papa kua oti, ā, kia tukuna e te taputapu he urupare whakarongo me te tirohanga (hei tauira, he tohu LED e whakamārama ana ina whakautua te waea) mō ngā kaiwhakamahi turi kore.

Mō te haumarutanga arorau, ka pāngia te whirihoranga o ngā intercom ataata SIP e ngā ture tūmataitinga raraunga pēnei i te General Data Protection Regulation (GDPR). Mena kua whakaritea te intercom ki te hopu ataata tonu ki tētahi Network Video Recorder (NVR) mā te kawa ONVIF, me whirihora e ngā kaiwhakahaere ngā kaupapa here pupuri aunoa. Hei whakatutuki i ngā mātāpono whakaiti raraunga, me whakakore ngā raraunga ataata me ngā raraunga waea SIP i muri i tētahi paepae pakari, pēnei i te matapihi hurihuri 30-rā, ki te kore e tohua mō tētahi rangahau haumarutanga motuhake.

Te Whakatūnga, te Whakamātautau, me te Tiaki Tonu

Ko te wāhanga whakamutunga ko te whakatūnga, te whakamātautau pakari, me te whakatū i ngā tikanga tiaki tonu. I te wā e whakatūngia ana, me manatoko e ngā tohunga hangarau te tūnga rēhitatanga SIP, me whakamana kei te tika te whakamahinga o ngā tohu QoS puta noa i ngā hop whatunga katoa, me te whakamātautau i te whakawhiti DTMF kia mōhio ai ka motu te patu tatau ā-tinana me te wā tika (ko te tikanga he roanga iriti 3 ki te 5 hēkona). Mena ka puta he hapa kiritaki SIP 4xx, he hapa tūmau 5xx rānei, ka whakamahia e ngā kaihanga whatunga ngā taputapu hopu pākete (PCAP) pēnei i a Wireshark hei whai i te tohu SIP me te tautuhi i ngā whirihoranga hē i roto i te mahere waea PBX, i ngā ture NAT pareārai rānei.

Mō te tiaki tonu, he mea nui te whakatū i tētahi kaupapa whakahou pūmanawa hei whakatika i ngā ngoikoretanga VoIP hou kua kitea. Nā te mea he taputapu haumarutanga nui ngā waea whakawhitiwhiti SIP, me whiriwhiri e ngā kaihoko hinonga he taputapu kua whakamātauhia he Wā Waenga i waenganui i ngā Rahunga (MTBF) neke atu i te 50,000 hāora. Mā te hono i ngā taputapu MTBF teitei me te aroturuki whatunga aunoa ka noho tonu te pūnaha waea whakawhitiwhiti SIP hei wāhanga pono, haumaru, me te wātea nui o te rautaki whakahaere urunga whānui a te whakahaere.
