IP telephony sikuti imangokhudza zida zodziwikiratu komanso zodziwika bwino, monga PBX ndi mafoni olumikizidwa nazo. Njira yolumikizirana pafoni ingaphatikizepo zida zomwe sizimapereka kulumikizana pakati pa olembetsa, koma kulumikizana kosiyana komwe timakumana nako komanso komwe sitikuzindikira. Pano, mu elevator ya malo ogulitsira, nyimbo zosasangalatsa zikusewera, mu sitolo amalengeza kuchotsera ndi zinthu zatsopano, mu nthambi ya banki mawu osangalatsa amatchula chiwerengero cha mzere wanu wamagetsi, mphunzitsi amachititsa semina kwa omvera ambiri, m'bwalo la zisudzo "belu lachitatu" likumveka, wolengeza akulengeza kukwera kwa ndege yanu, Ku bizinesi, antchito amamva chilengezo cha liwu. Pomaliza, mkhalidwe womwe ndikukhumba kuti musadzipeze nokha: kuchenjeza alendo ndi ogwira ntchito zadzidzidzi ndikuwafunsa kuti achoke mnyumbamo.
Zonsezi ndizotheka chifukwa cha njira zoyankhulirana ndi anthu.
Mu bungwe lililonse lomwe likufunika kulengeza kwa ogwira ntchito ndi alendo, muyenera kuganizira momwe izi zidzachitikire. Mutha kuchita mwanjira yakale - mukumangirira mapepala, mutha kufuula mu "bokosi lolumbira" kapena kuliza belu. Koma mauthenga amakono amapangitsa kuti ntchitoyi ikhale yosavuta. Pafupifupi kulikonse, kuchokera ku ofesi yaying'ono ya anthu angapo kupita ku hotelo, IP telephony imagwiritsidwa ntchito. Choncho, n’zomveka kupanga chenjezo pamaziko ake. Nkhaniyi ifotokoza za chipangizo cha Snom PA1, chomwe ndi yankho lokonzeka kuyankha pagulu.
Snom PA1 ndi gawo la IP lomwe limaphatikiza chipangizo cholembetsa cha SIP ndi amplifier. Thupi laling'ono (160x120 mm) komanso lolimba la "audiophile" lopangidwa ndi aluminiyamu ya anodized yolemera pafupifupi magalamu 200 limatha kupachikidwa pakhoma kapena padenga. Miyeso yake yophatikizika imalola kuti ibisike kumbuyo kwa denga labodza kapena gulu logawa.
Pali mipata m'mbali mwamilandu momwe "makutu" amayikidwa kuti amangirire PA1:
PA1 ndi chipangizo cholowera; ilibe mawonekedwe opanda zingwe ndipo imatha kulumikiza cholankhulira chimodzi. Routa yapawiri-port 10/100 megabit router imakupatsani mwayi wolumikiza angapo amplifiers kwa wina ndi mzake ndikulumikiza webukamu. Multicast protocol imathandizidwanso, yomwe mutha kuwulutsa ku gulu la ma module angapo a PA1. Amplifier ya digito ya Class D ili ndi mphamvu ya ma watts 4 ndipo imatha kulumikizidwa ndi zokuzira mawu zilizonse zoyenera pama adilesi a anthu.
Pamapeto pake pali madoko awiri a Efaneti, amodzi omwe amatha kupereka mphamvu mwachindunji kudzera pa chingwe cha netiweki (PoE). Palinso cholumikizira chamagetsi 12-volt (osaphatikizidwa). Kumanzere pali batani lokhazikitsira / pezani IP, komanso ma LED awiri omwe amagwiritsidwa ntchito kuwonetsa magwiridwe antchito a chipangizocho ndikuwonetsa momwe mukuchikonza.
Kumbali inayo kuli ma terminal olumikizira wokamba nkhani ndi jack ya mahedifoni, omwe, pamodzi ndi keypad yapadera ya DTMF, angagwiritsidwe ntchito kukonza PA1. Njira yodziwira mphamvu yamagetsi IP ma adilesi: muyenera kukanikiza batani lapadera ndipo amplifier idzauza adilesi ya mahedifoni olumikizidwa.
Kuphatikiza apo, PA1 ili ndi zolumikizira zingapo zamitundu yambiri, zomwe ntchito zake zimaperekedwa kudzera pa intaneti. Nthawi zambiri amagwiritsidwa ntchito polumikizana ndi ma alarm ndi masensa oyang'anira makanema. Mawonekedwe a intaneti amakupatsani mwayi wokhazikitsa adilesi ya IP ya amplifier, kukhazikitsa mawu achinsinsi, kusintha voliyumu ya okamba ndikusintha firmware.
Kugwiritsa ntchito PA1 ndikosavuta: "ingoyimbirani" kuchokera pa foni kapena kompyuta iliyonse yolumikizidwa ndi netiweki ya telephony ya IP ndikulengeza zomwe mukufuna mu maikolofoni.
Ubwino waukulu wa Snom PA1 poyerekeza ndi machenjezo achikhalidwe ndi mtengo wake komanso kumasuka kwa kutumiza. Machitidwe achikhalidwe amafuna kuyala zingwe zosiyana kumalo oyikapo, zomwe zimawononga ndalama zambiri. Koma pankhani ya PA1, chipangizocho chimakhala ndi mtengo wofanana ndi foni yamakono yotsika mtengo, ndipo imatha kukhazikitsidwa paliponse pomwe chingwe chopindika chokhazikika chayikidwa kale.
