Instalar chan_dongle en Isabel 4 con asterisk 11

por

Para los que no lo sepan Issabel PBX es el proyecto que continuo con el legado del extinto proyecto elastix, muchos colaboradores del anterior proyecto se sumaron en una nueva aventura y dieron forma a Issabel una solución PBX al mero estilo de Elastix: fácil de manejar e intuitiva en su configuración.

En este manual explicare como instalar chan_dongle para tener un Gateway GSM operativo al 100% en conjunto con Isabbel PBX, no entrare en tema en como instalar Issabel puesto que existen infinidad de manuales e internet para poder instalar Issabel, por lo cual, partiré que ya tienen Issabel PBX funcionando y con una sesión de root lista.

NOTA: A día de hoy Issabel PBX se encuentra en su version 47, que nos brinda la posibilidad de realizar la instalación con diversas versiones de asterisk, para este manual emplee la version 11 (como lo indica el título del manual).

issabel-pbx-4-chan_dongle
issabel-pbx-4-chan_dongle

Configurando e instalando chan_dongle en Issabel 4

Para comenzar con la instalación deberemos instalar algunas dependencias:

  1. yum install git
yum install git

Después dentro del directorio de /root/ (por practicidad) procederemos a clonar el repositorio de chan_dongle:

  1. [root@issabel ~]# git clone https://github.com/wdoekes/asterisk-chan-dongle
[root@issabel ~]# git clone https://github.com/wdoekes/asterisk-chan-dongle

Después empezaremos el proceso de compilación:

  1. [root@issabel asterisk-chan-dongle]# ./bootstrap
  2. configure.ac:6: installing './config.guess'
  3. configure.ac:6: installing './config.sub'
  4. configure.ac:7: installing './install-sh'
  5. configure.ac:7: installing './missing'
[root@issabel asterisk-chan-dongle]# ./bootstrap
configure.ac:6: installing './config.guess'
configure.ac:6: installing './config.sub'
configure.ac:7: installing './install-sh'
configure.ac:7: installing './missing'

Despues:

  1. [root@issabel asterisk-chan-dongle]# make install
  2. strip chan_dongle.so
  3. /usr/bin/install -c -m 644 chan_dongle.so /usr/lib64/asterisk/modules
[root@issabel asterisk-chan-dongle]# make install
strip chan_dongle.so
/usr/bin/install -c -m 644 chan_dongle.so /usr/lib64/asterisk/modules

Después una vez generado el modulo, procederemos a copiarlo al directorio de asterisk:

  1. cp /root/asterisk-chan-dongle/etc/dongle.conf /etc/asterisk/
cp /root/asterisk-chan-dongle/etc/dongle.conf /etc/asterisk/

Después ingresaremos a asterisk y cargaremos el modulo recién compilado:

En este instante, deberemos conectar nuestro modem y en “teoría” debería de funcionar pero resulta que nos arroja un error:

Esto hace alusión a que el dispositivo /dev/ttyUSBX no puede ser accedido por asterisk, esto es un tema de permisos por lo que debemos de cambiarle permisos al dispositivo, esto lo logramos con:

  1. [root@issabel asterisk-chan-dongle]# chmod 777 /dev/ttyUSB*
[root@issabel asterisk-chan-dongle]# chmod 777 /dev/ttyUSB*

Donde después volveremos a ingresar a asterisk y nos percataremos que ya está funcionando y operativo nuestro modem:

Configurar Isabel vía Web para llamar a travez de chan_dongle

Ahora una vez que está configurado y cargado el módulo de chan_dongle procedemos a acceder a la interface web de Issabel para poder ejecutar llamadas a través de nuestro nuevo gateway GSM.

Lo primero que haremos será generar una extensión, esto lo realizaremos (como en el viejo Elastix) dentro de:

PBX > Configuración PBX > Extensiones > Añadir una extensión > Dispositivo SIP genérico > Enviar

No voy a explicar cómo crear una extensión dentro de Issabel/Elastix porque es algo bastante documentado en internet, pero solo mencionare que es fundamental tener presente el usuario/número de extensión y el password generado o el secret (como lo nombra Issabel).

extension-Issabel-PBX
extension-Issabel-PBX

Para validar que nuestra extensión configurada se registró de manera correcta en nuestro PBX veremos un mensaje como el siguiente en la consola:

  1. Registered SIP '1337' at 172.16.151.1:59107
  2. > Saved useragent "Z 5.3.5 rv2.9.26-mod" for peer 1337
  3. [2020-01-31 15:19:51] NOTICE[9341]: chan_sip.c:23892 handle_response_peerpoke: Peer '1337' is now Reachable. (1ms / 2000ms)
Registered SIP '1337' at 172.16.151.1:59107
> Saved useragent "Z 5.3.5 rv2.9.26-mod" for peer 1337
[2020-01-31 15:19:51] NOTICE[9341]: chan_sip.c:23892 handle_response_peerpoke: Peer '1337' is now Reachable. (1ms / 2000ms)

Una vez que tenemos registrada nuestra extensión generaremos una troncal, esto lo realizaremos en:

PBX > Configuración PBX > Básico > Troncales > Añadir línea troncal personalizada

troncal-GSM-Issabel
troncal-GSM-Issabel

Donde los datos importantes serán el nombre de la troncal (para temas de identificación/control) y la “Cadena de marcación peronalizada”, que como vemos en la imagen es:

  1. dongle/dongle0/$OUTNUM$
dongle/dongle0/$OUTNUM$

Esto es de suma importancia para que salgan las llamadas.
Después de realizado esto procederemos a generar una “Ruta Saliente” esto lo podremos efectuar desde:
PBX > Configuración PBX > Básico > Rutas Salientes > Añadir ruta

ruta-de-salida-Issabel-GSM
ruta-de-salida-Issabel-GSM

Donde los datos más importantes serán: “Dial Patterns that will use this Route” que básicamente es la coincidencia en la marcación, en este caso emplee un “punto” que nos dice que todo lo que se marque saldrá por ahí, de igual forma, otro campo importante es “Trunk Sequence for Matched Routes” que es la ruta que empleara para sacar el tráfico, en la imagen aparece seleccionada la troncal chan_dongle porque es así como nombre la troncal personalizada en el paso anterior.

Una vez efectuados todos los pasos que se mencionaron anteriormente, en la consola de asterisk podremos observar la correcta salida de las llamadas cuando marcamos a un número cualquiera des nuestra extension: 5556581111 (una dependencia de gobierno aquí en MX).

De esta forma ya tendríamos configurado chan_dongle e Issabel y se encontrarían listos para sacar cualquier cantidad de tráfico que deseemos.
