El futur de les telecomunicacions passa per la tecnologia IP. Aquesta afirmaci\u00f3n conven\u00e7 cada cop a m\u00e9s companyies, que en l\u0092’\u00faltima d\u00e8cada han apostat per la telefonia IP o VoIP en les seves comunicacions corporatives. <\/strong>Tot i amb aix\u00f2, algunes organitzacions s\u00f3n encara reticents a adoptar aquestes solucions degut a una s\u00e8rie de \u0093falses creences\u0094 que analitzem a continuaci\u00f3:<\/p>\n

    \n
  1. \u0093La telefonia IP \u00e9s nom\u00e9s per estalviar costos\u0094<\/strong><\/li>\n<\/ol>\n

    Existeix l\u0092idea de que l\u0092’\u00fanic avantatge que ofereix la telefonia IP \u00e9s obtenir preus molt competitius<\/strong> en les trucades de llarga dist\u00e0ncia, per\u00f2 en realitat aquest nom\u00e9s \u00e9s un dels seus beneficis. Gr\u00e0cies a la implementaci\u00f3 de la Veu sobre IP les organitzacions, sense importar les seves dimensions i el sector en el que operen, poden beneficiar-se d\u0092una s\u00e8rie de funcionalitats d\u0092’alt valor afegit<\/strong> que s\u0092’adapten a les seves necessitats en cada moment, a un preu i una inversi\u00f3 redu\u00efts.\u00a0<\/strong><\/p>\n

      \n
    1. \u0093 La qualitat de l\u0092’\u00e0udio no \u00e9s bona\u0094 <\/strong><\/li>\n<\/ol>\n

      \u00c9s possible que fa 10 o 15 anys aix\u00f2 fos cert, per\u00f2 la tecnologia ha evolucionat des d\u0092’aleshores. La telefonia IP permet que la senyal de veu viatgi per Internet a trav\u00e9s de canals compartits. Per a fer-ho, tota la informaci\u00f3 es divideix en paquets de dades<\/strong> amb el seu propi encap\u00e7alament d\u0092’origen i el seu dest\u00ed, on es tornen a ordenar. Per tal d\u0092’assegurar que aquests paquets arribin de forma correcta i evitar aix\u00ed possibles incid\u00e8ncies com la lat\u00e8ncia<\/strong>, el jitter<\/strong> o que arribin a la seva destinaci\u00f3 de la forma incorrecta, nom\u00e9s cal prioritzar el tr\u00e0fic de veu a la xarxa, per davant del de dades.<\/p>\n

      A la telefonia IP, la qualitat de veu tamb\u00e9 dep\u00e8n en gran mesura del c\u00f2dec de comprensi\u00f3<\/strong> utilitzat. A major comprensi\u00f3, menor \u00e9s l’\u00fas d’ample de banda, per\u00f2 tamb\u00e9 ser\u00e0 menor la qualitat de l’\u00e0udio. Amb el c\u00f2dec G.729 s’aconsegueix un bon equilibri entre el consum d’ample de banda. Aix\u00ed, l’\u00fas d’ample de banda es major, i s’aconsegueix una qualitat superior a la de la telefonia tradicional.<\/p>\n

        \n
      1. \u0093Telefon\u00eda IP: o tot, o res<\/strong><\/li>\n<\/ol>\n

        Una soluci\u00f3 de telefonia IP no implica necess\u00e0riament haver de desprendre’s de la infraestructura actual<\/strong>. Si recentment s’ha realitzat una important inversi\u00f3 en una centraleta i els seus terminals associats, no \u00e9s necessari desprendre’s d’aquests actius. Els serveis de Sip Trunk<\/a> permeten connectar la centraleta existent a la xarxa de l’operador del servei de telefonia IP, i comen\u00e7ar a gaudir de les tarifes i els m\u00faltiples avantatges de la telefonia al n\u00favol, com la numeraci\u00f3 global<\/a>, la gravaci\u00f3 de trucades<\/a>, la gesti\u00f3 de locucions<\/a>, etc.<\/p>\n

          \n
        1. \u0093La telefon\u00eda IP t\u00e9 errors de seguretat\u0094<\/strong><\/li>\n<\/ol>\n

          La seguretat segueix sent una de les principals inquietuds que expressen les empreses <\/strong>a l’\u0092hora d\u0092’adoptar un sistema de comunicacions basat a Internet. No obstant, existeixen diferents mecanismes que permeten protegir-se de possibles atacs, entre ells la instal\u00b7laci\u00f3 de firewalls<\/em> o l\u0092’habilitaci\u00f3 de protocols de xifrat. Aquests \u00faltims impedeixen, en el cas de\u00a0que tingui lloc un acc\u00e8s indegut, que les dades puguin ser utilitzades.<\/p>\n","protected":false},"excerpt":{"rendered":"
