Dicho protocolo permite crear, modificar y finalizar sesiones multimedia con uno o m\u00e1s participantes y sus mayores ventajas recaen en su simplicidad y consistencia.<br \/>\nHasta la fecha, exist\u00edan m\u00faltiples protocolos de se\u00f1alizaci\u00f3n tales como el H.323 de la ITU, el SCCP de Cisco, o el MGCP, pero parece que poco a poco SIP est\u00e1 ganando la batalla del est\u00e1ndar: Cisco est\u00e1 progresivamente adoptando SIP como protocolo en sus sistemas de telefon\u00eda IP en detrimento de H.323 y SCCP, Microsoft ha eligido SIP como protocolo para su nuevo OCS (Office Communication Server), y los operadores (de m\u00f3vil y fijo) tambi\u00e9n est\u00e1n implantando SIP dentro de su estrategia de convergencia, aprovechando de este modo la escalabilidad y interoperabilidad que nos proporciona el protocolo SIP.<\/p>\n<p><strong>Funciones SIP<\/strong><\/p>\n<p>El protocolo SIP act\u00faa de forma transparente, permitiendo el mapeo de nombres y la redirecci\u00f3n de servicios ofreciendo as\u00ed la implementaci\u00f3n de la IN (Intelligent Network) de la PSTN o RTC.<br \/>\nPara conseguir los servicios de la IN el protocolo SIP dispone de distintas funciones. A continuaci\u00f3n se enumeran las m\u00e1s importantes:<\/p>\n<p>*Localizaci\u00f3n de usuarios (SIP proporciona soporte para la movilidad).<br \/>\n*Capacidades de usuario (SIP permite la negociaci\u00f3n de par\u00e1metros).<br \/>\n*Disponibilidad del usuario<br \/>\n*Establecimiento y mantenimiento de una sesi\u00f3n.<\/p>\n<p>En definitiva, el protocolo SIP permite la interacci\u00f3n entre dispositivos, cosa que se consigue con distintos tipos de mensajes propios del protocolo que abarca esta secci\u00f3n. Dichos mensajes proporcionan capacidades para registrar y\/o invitar un usuario a una sesi\u00f3n, negociar los par\u00e1metros de una sesi\u00f3n, establecer una comunicaci\u00f3n entre dos a m\u00e1s dispositivos y, por \u00faltimo, finalizar sesiones.<\/p>\n<p>\n<div id=\"rev_slider_3_1_wrapper\" class=\"rev_slider_wrapper fullwidthbanner-container\" style=\"float:left;background-color:#E9E9E9;padding:0px;margin-left:0px;margin-right:0px;margin-top:0px;margin-bottom:0px;\">\n<!-- START REVOLUTION SLIDER 5.0.9 auto mode -->\n\t<div id=\"rev_slider_3_1\" class=\"rev_slider fullwidthabanner\" style=\"display:none;\" data-version=\"5.0.9\">\n<ul>\t<!-- SLIDE  -->\n\t<li data-index=\"rs-28\" data-transition=\"random\" data-slotamount=\"7\"  data-easein=\"default\" data-easeout=\"default\" data-masterspeed=\"300\"  data-thumb=\"\"  data-rotate=\"0\"  data-saveperformance=\"off\"  class=\"voipswitch videos subtitulos\" id=\"voipswitch videos subtitulos\" voipswitch videos subtitulos data-title=\"SubtitulosTexto\" data-description=\"\">\n\t\t<!-- MAIN IMAGE -->\n\t\t<img src=\"https:\/\/servervoip.com\/blog\/wp-content\/plugins\/revslider\/admin\/assets\/images\/dummy.png\"  alt=\"\"  width=\"879\" height=\"51\" data-lazyload=\"https:\/\/servervoip.com\/blog\/wp-content\/plugins\/revslider\/admin\/assets\/images\/transparent.png\" data-bgposition=\"center top\" data-bgfit=\"cover\" data-bgrepeat=\"no-repeat\" class=\"rev-slidebg\" data-no-retina>\n\t\t<!-- LAYERS -->\n\n\t\t<!-- LAYER NR. 1 -->\n\t\t<div class=\"tp-caption   tp-resizeme\" \n\t\t\t id=\"slide-28-layer-2\" \n\t\t\t data-x=\"\" \n\t\t\t data-y=\"1\" \n\t\t\t\t\t\tdata-width=\"['none','none','none','none']\"\n\t\t\tdata-height=\"['none','none','none','none']\"\n\t\t\tdata-transform_idle=\"o:1;\"\n \n\t\t\t data-transform_in=\"opacity:0;s:300;e:Power2.easeInOut;\" \n\t\t\t data-transform_out=\"opacity:0;s:300;s:300;\" \n\t\t\tdata-start=\"500\" \n\t\t\tdata-responsive_offset=\"on\" \n\n\t\t\t\n\t\t\tstyle=\"z-index: 5;\">\n\t\t\t\t<div class=\"rs-looped disabled\" ><img src=\"https:\/\/servervoip.com\/blog\/wp-content\/plugins\/revslider\/admin\/assets\/images\/dummy.png\" alt=\"\" data-ww=\"879\" data-hh=\"51\" data-lazyload=\"https:\/\/www.servervoip.com\/blog\/wp-content\/uploads\/2015\/10\/fondo-en-degradado-con-signod-copia.jpg\" data-no-retina> \n\t\t\t\t<\/div>\n\t\t<\/div>\n\n\t\t<!-- LAYER NR. 2 -->\n\t\t<div class=\"tp-caption mediumbgorange   tp-resizeme\" \n\t\t\t id=\"slide-28-layer-1\" \n\t\t\t data-x=\"6\" \n\t\t\t data-y=\"5\" \n\t\t\t\t\t\tdata-width=\"['653']\"\n\t\t\tdata-height=\"['41']\"\n\t\t\tdata-transform_idle=\"o:1;\"\n \n\t\t\t data-transform_in=\"opacity:0;s:300;e:Power3.easeInOut;\" \n\t\t\t data-transform_out=\"auto:auto;s:300;\" \n\t\t\tdata-start=\"500\" \n\t\t\tdata-splitin=\"none\" \n\t\t\tdata-splitout=\"none\" \n\t\t\tdata-responsive_offset=\"on\" \n\n\t\t\t\n\t\t\tstyle=\"z-index: 6;
