Comando FOR para archivos BAT

Gracias a: http://profesoremiliobarco.blogspot.com/ El comando FOR sirve para ejecutar bucles de instrucciones, y es una instrucción que se encuentra disponible en todos los lenguajes de programación. Un bucle son varias repeticiones de algunas instrucciones. Este comando suele ser el más complicado de entender para las personas que empiezan a escribir archivos BAT complejos. Aqui intentaré explicar todas las opciones y usos del comando FOR, así como intentar resolver las dudas que los usuarios de Internet me puedan plantear. La sintaxis normal del comando FOR es: FOR %var IN (lista) DO (      comando     comando      ... )  Pero si lo vamos a usar dentro de un archivo BAT será así: FOR %%var IN (lista) DO (      comando     comando      ... ) Observa que la variable "var" ahora va precedida por dos simbolos de "%".

How to connect two Asterisk PBXs using a SIP Peer/User Trunk Pairing

Imagen
Thanks to:  https://www.telecomworld101.com/   Session Initiation Protocol (SIP)) is a signalling protocol used for setting up and tearing down Voice over Internet Protocol (VOIP)  calls . Voice over Internet Protocol makes the transition from traditional conference calls to  conference calling  via the world wide web. A SIP call uses two protocols: SIP and RTP. Real Time Protocol (RTP) is used for the transfer of the actual voice data. If you want to find out more about SIP visit Wikipedia's  SIP page . The first step in setting up an SIP trunk is to draw a picture of what you need to do. Here's an example of a simple PBX to PBX  connection  that will be using a User/Peer pairing to form a SIP trunk. The two PBXs are name 106 and 111 after their IP host address. They could very well be named Montreal and New York. PBX 106 has all their extensions starting with 3xxx while PBX 111 has all of their extensions starting with 2xxx. This will be handy w...
