Es común pensar que se debe elegir el servidor más cercano a su localidad, sin embargo esto no es necesario en la mayoría de las veces. Si usted está en Estados Unidos, cualquier servidor en EEUU le debe dar un buen resultado en latencia y calidad. También es de utilidad saber que hay una herramienta que le puede ayudar a seleccionar el mejor servidor a usar, este normalmente se llama "ping", el cual le provee la latencia entre usted y el servidor, así usted opcionalmente puede elegir específicamente el servidor que le provea una menor latencia. '''Nota:''' Tenga en cuenta que es posible que algunos servidores no estén disponibles para que su número DID se utilice como POP (Punto de presencia) en la sección "Administrar DID". Asegúrese de que su dispositivo SIP / IAX y su número de teléfono apunten al mismo servidor. === IPs === <div><ul> <li style="display: inline-block; vertical-align:top;"> '''Canada''' *Montreal 1, QC ('''montreal.voip.ms''') 192.175.96.73 *Montreal 2, QC ('''montreal2.voip.ms''') 192.175.96.74 *Montreal 3, QC ('''montreal3.voip.ms''') 192.175.96.68 *Montreal 4, QC ('''montreal4.voip.ms''') 67.205.74.179 *Montreal 5, QC ('''montreal5.voip.ms''') 192.175.96.69 *Montreal 6, QC ('''montreal6.voip.ms''') 192.175.96.70 *Montreal 7, QC ('''montreal7.voip.ms''') 192.175.96.71 *Montreal 8, QC ('''montreal8.voip.ms''') 192.175.96.72 *Montreal 9, QC ('''montreal9.voip.ms''') 67.205.74.184 *Montreal 10, QC ('''montreal10.voip.ms''') 67.205.74.187 *Toronto 1, ON ('''toronto.voip.ms''') 158.85.70.148 *Toronto 2, ON ('''toronto2.voip.ms''') 158.85.70.149 *Toronto 3, ON ('''toronto3.voip.ms''') 158.85.70.150 *Toronto 4, ON ('''toronto4.voip.ms''') 158.85.70.151 *Toronto 5, ON ('''toronto5.voip.ms''') 184.75.215.106 *Toronto 6, ON ('''toronto6.voip.ms''') 184.75.215.114 *Toronto 7, ON ('''toronto7.voip.ms''') 184.75.215.146 *Toronto 8, ON ('''toronto8.voip.ms''') 184.75.213.210 *Toronto 9, ON ('''toronto9.voip.ms''') 158.85.70.154 *Toronto 10, ON ('''toronto10.voip.ms''') 158.85.70.158 *Vancouver 1, BC ('''vancouver.voip.ms''') 162.213.157.220 *Vancouver 2, BC ('''vancouver2.voip.ms''') 162.213.157.117 *Vancouver 3, BC ('''vancouver3.voip.ms''') 162.213.157.82 </li> <li style="display: inline-block; vertical-align:top;"> '''Estados Unidos''' *Atlanta 1, GA ('''atlanta.voip.ms''') 75.127.65.130 *Atlanta 2, GA ('''atlanta2.voip.ms''') 209.217.224.50 *Chicago 1, IL ('''chicago.voip.ms''') 208.100.39.52 *Chicago 2, IL ('''chicago2.voip.ms''') 208.100.39.53 *Chicago 3, IL ('''chicago3.voip.ms''') 208.100.39.54 *Chicago 4, IL ('''chicago4.voip.ms''') 208.100.39.55 *Chicago 5, IL ('''chicago5.voip.ms''') 50.31.115.149 *Chicago 6, IL ('''chicago6.voip.ms''') 50.31.115.150 *Chicago 7, IL ('''chicago7.voip.ms''') 50.31.115.151 *Dallas, TX ('''dallas.voip.ms''') 158.85.149.162 *Dallas 2, TX ('''dallas2.voip.ms''') 158.85.149.163 *Denver 1, CO ('''denver.voip.ms''') 23.239.211.90 *Denver 2, CO ('''denver2.voip.ms''') 64.27.52.226 *Houston, TX ('''houston.voip.ms''') 205.251.137.130 *Houston 2, TX ('''houston2.voip.ms''') 74.81.95.146 *Los Angeles 1, CA ('''losangeles.voip.ms''') 104.254.128.162 *Los Angeles 2, CA ('''losangeles2.voip.ms''') 104.254.128.2 *Los Angeles 3, CA ('''losangeles3.voip.ms''') 64.188.6.162 *Los Angeles 4, CA ('''losangeles4.voip.ms''') 64.188.6.170 *New York 1, NY ('''newyork.voip.ms''') 72.251.239.196 *New York 2, NY ('''newyork2.voip.ms''') 72.251.239.205 *New York 3, NY ('''newyork3.voip.ms''') 72.251.239.206 *New York 4, NY ('''newyork4.voip.ms''') 72.251.239.207 *New York 5, NY ('''newyork5.voip.ms''') 23.29.136.28 *New York 6, NY ('''newyork6.voip.ms''') 23.29.136.29 *New York 7, NY ('''newyork7.voip.ms''') 23.29.136.38 *New York 8, NY ('''newyork8.voip.ms''') 23.29.136.40 *San Jose, CA ('''sanjose.voip.ms''') 23.246.247.146 *San Jose 2, CA ('''sanjose2.voip.ms''') 23.246.247.147 *Seattle 1, WA ('''seattle.voip.ms''') 50.23.160.53 *Seattle 2, WA ('''seattle2.voip.ms''') 50.23.149.166 *Seattle 3, WA ('''seattle3.voip.ms''') 50.23.160.54 *Tampa, FL ('''tampa.voip.ms''') 162.254.144.173 *Tampa 2, FL ('''tampa2.voip.ms''') 209.133.209.70 *Tampa 3, FL ('''tampa3.voip.ms''') 23.111.187.139 *Tampa 4, FL ('''tampa4.voip.ms''') 23.111.166.202 *Washington 1, DC ('''washington.voip.ms''') 169.62.41.187 *Washington 2, DC ('''washington2.voip.ms''') 169.62.41.189 </li> <li style="display: inline-block; vertical-align:top;"> '''Internacional''' *Amsterdam, NL ('''amsterdam.voip.ms''') 66.212.22.42 *London, UK ('''london.voip.ms''') 159.8.157.212 *Paris, FR ('''paris.voip.ms''') 159.8.85.180 </li> </ul></div> ===Dominios del Servidor=== Para IOS, haga clic aquí [http://wiki.voip.ms/article/Server_Realms Server Realms] para obtener el nombre de dominio para el servidor que planea usar, esto puede diferir del nombre de dominio que se está utilizando. = ¿Qué es un Ping? = Ping es la herramienta estándar usada para probar la latencia (demora) en conexiones en red. Normalmente es usada para determinar si un servidor o dispositivo puede ser alcanzado a través de la red y su tiempo de latencia (tiempo que toma en enviarse un paquete a su destino y regresar a su origen) para responder. La herramienta Ping es parte de Windows, MAC OS y Linux, también se puede encontrar en algunos ruteadores. == ¿Cómo funciona la herramienta Ping? == Esta envía mensajes de petición a un una dirección de red determinada o nombres DNS en ciertos intervalos de tiempo y contabiliza el tiempo que tarda en recibirse un mensaje de respuesta. (mejor conocido como tiempo de latencia) ==¿Cómo hacer un ping en una PC?== Hacer ping es un comando que le dice si la conexión entre su computadora y un dominio en particular está funcionando correctamente. En Windows, seleccione Inicio> Programas> Accesorios> Símbolo del sistema. Esto le dará una ventana como la de abajo. Ingrese la palabra ping, seguida de un espacio, luego el nombre de dominio (montreal.voip.ms) en este caso, el dominio es el nombre de nuestro servidor. Si los resultados muestran una serie de respuestas, la conexión está funcionando. El tiempo te muestra qué tan rápida es la conexión. Si ves un error de "tiempo de espera agotado" en lugar de una respuesta, hay una falla en algún lugar entre tu computadora y el dominio. [[File:Ping.gif|thumb|none|600px|Ping]] == ¿Cómo enviar un ping a una MAC? == 1- Haga click en el buscador en la barra de herramientas. 2- Haga click en aplicaciones. 3- Haga click en utilidades (usos / configuraciones). 4- Haga doble-click en utilidades de red.&#42; &#42;En OS X Mavericks (10.9.x), esta aplicación de utilidad cambió de ubicación. En su lugar, inícielo desde Spotlight, presione "comando" + "barra espaciadora" o haga clic en Spotlight directamente (icono de lupa en la parte superior derecha de la pantalla), escriba "utilidad de red" y presione "regresar" 5- En la ventana de utilidades de red, haga click en el el cuadro de ping. 6- En el campo debajo "Ingresese la direccion de red para hacer ping," como montreal.voip.ms '' Si el ping resulta no ser consistente, puede tener un problema de ''jitter'' (variación del tiempo que tardan en llegar los paquetes debido a una congestión en la red o a diferentes rutas tomadas). Para tratar este problema, puede ajustar el nivel de ''jitter'' en su configuración del dispositivo VoIP (si cuenta con esta opción). Normalmente es recomendado un ping por debajo de 150ms para tener una buena calidad de audio durante la llamada. El tiempo de latencia del servidor es importante, sin embargo hay otros factores importantes a tomar en cuenta para la calidad de las llamadas como son la pérdida de paquetes (las comunicaciones VoIP son muy sensibles a esto) y el nivel de ''jitter'' de su conexión a Internet.

Una latencia alta provocará un retraso y ecos en la comunicación. La latencia se mide en milisegundos (ms) Por ejemplo: una latencia de 150 ms es apenas perceptible, por lo que es aceptable. Más alto que eso, la calidad comienza a sufrir. Cuando supera los 300 ms, se vuelve inaceptable. [[category:Guías]]
