Centralita Asterisk VoIP - VoIPBuster - Google Talk

Esto es un recopilatorio de diversas guías y basado fundamentalmente en un estupendo post, unificando una configuración que haga lo siguiente:

• Red interna de extensiones con teléfonos IP y teléfonos móviles con cliente Zoiper en la misma red mediante wifi.
• Salida de llamadas con prefijo 0034 por Voipbuster u otro proveedor de SIP.
• Salida y recepción de llamadas mediante Gtalk en una una extensión fija.

Configuramos Asterisk 11.X en nuestra raspberry pi o beaglebone por ejemplo, y que ya incluye los módulos necesarios; los ficheros de configuración son como siguen:

extensions.conf

[default]

; definición de cada una de las extensiones fijas 

exten => _1XX,1,answer()

exten => _1XX,n,dial(sip/${EXTEN}) 

exten => _1XX,n,hangup() 

[entrante-gtalk]

include => saliente-gtalk

exten => s,1,NoOp()

 same => n,Wait(1) same => n,Answer() same => n,SendDTMF(1)

; 102 será la extensión que sonará cuando nos llamen por gtalk. 

 same => n,Dial(SIP/102,20)   

 [saliente-gtalk]

exten => 555,1,Dial(Motif/google/contacto@gmail.com,,r) 

[voipbuster]

; los prefijos 0034 se envián por la cuenta de voipbuster 

exten => _0034.,1,Dial(SIP/${EXTEN}@voipbuster) 

motif.conf

[google]
context=entrante-gtalk     ; Las llamadas proceden de o finalizan del contexto entrante-gtalk
disallow=all               ; No se permite ningun codec
allow=ulaw                 ; Permite el codec G.711 ulaw
connection=google          ; La conexion XMPP llamada "google" se usara para realizar la conexion

xmpp.conf

[general]
[google]
type=client                    ; Es tipo cliente ya que Google esta dando un servicio
serverhost=talk.google.com     ; El servidor de gtalk
username=tucuenta@gmail.com     ; El usuario de gtalk que se usara para conectarse
secret=contraseña              ; El password de tu usuario de gtalk
priority=1                     ; La prioridad
port=5222                      ; El puerto por el cual opera gtalk
usetls=yes                     ; La encriptacion TLS requerida por Google
usesasl=yes                    ; SASL usada por Google
status=available               ; Estatus como se mostrara en gtalk
statusmessage="Conectado VoIP"   ; El mensaje que se mostrara en el gtalk
timeout=5                      ; Se establece un tiempo de espera para recibir un mensaje de Google que permite lo suficiente de tiempo en caso de retraso en la red

y finalmente sip.conf

[general]context=default                 allowoverlap=no                 bindport=5060                   bindaddr=0.0.0.0                tcpenable=yes                   tcpbindaddr=0.0.0.0             srvlookup=yes                   

[101]username=101secret=101type=friendcallerid="Ext. <101>"host=dynamiccontext=default

[102]username=102secret=102type=friendcallerid="Ext. <102>"host=dynamiccontext=entrante-gtalk

[voipbuster]type=peerhost=sip.voipbuster.comusername=cuenta_voipbuster   ; aquí va tu cuenta de voipbusterfromuser=cuenta_voipbuster   secret=contraseña_voipbuster   notifyringing=yesmusicclass=defaultnat=yes

Conectamos ahora un terminal o cliente softphone con la extensión 102, y cuando llamemos por gtalk a la cuenta tucuenta@gmail.com debería sonarnos en dicha extensión.

Si marcamos un número cuyo comienzo sea por 0034 deberá salir por Voipbuster, aplicándose las tarifas correspondientes. Si es un fijo y estamos en los 120 días tras una recarga, debería ser gratis.

Por último podremos llamar desde la extensión 101 por ejemplo a la 102; hay que tener en cuenta que hay dos context, default y entrantes-gtalk.

Seguimiento de aviones con ASL26555

Con LCD4Linux, Dump1090, y un sensor BMP085 por I2C tenemos un curioso router para seguir aviones y mostrar datos de temperatura y presión:

OpenWrt en Belkin Play Max F7D4401 v1

Router de muy interesantes especificaciones:  bandas 2.4 y 5 ghz, y  2 puertos USB 2.0. No hay casi soporte para routers de esta marca en OpenWrt, aunque tienen buenos precios y buenas prestaciones gracias al SoC BRCM4718.

En la Web encontramos ya soportados modelos inferiores como el F7D3301 o el F7D4301 (igual al F7D4401 pero sin módem adsl), en dd-wrt o tomato-usb, pero con parches mantenidos fuera del trunk de OpenWrt.

Este parche que permite arrancar el OpenWrt está basado en el trabajo de Manoj para adaptar los firmwares a la cabecera específica de Belkin y su adaptación al F7D3301 de los parches de George Kashperko para el F7D4301 y Asus RT-N16.

La modificación para que el CFE reconozca el firmware es mínima, y consiste únicamente en cambiar el número mágico de la cabecera TRX del firmware al específico del F7D4401 en el parche de Manoj.

Así se añade, en lugar del TRX_MAGIC estándar,

#define TRX_MAGIC   0x30524448

o de otros modelos Belkin basados en el mismo SoC:


#define TRX_MAGIC_F7D3301   0x20100322  
#define TRX_MAGIC_F7D3302   0x20090928
#define TRX_MAGIC_F7D4302   0x20091006


se añade el específico del F7D4401:

#define TRX_MAGIC_F7D4401   0x00018517

Queda por ir añadiendo soporte a la placa, leds, gpio, etc. OpenWrt no soporta el wifi en la banda de 5 ghz y tampoco el módel ADSL.

ONT I-240G-B MOVISTAR ALCATEL LUCENT

Muy interensante cacharro que monta movistar con fibra óptica... atención al latiguillo y como va cuidadósamente enrrollado ... lleva una cpu dual core bcm6818 aún no soportada en Openwrt, sin wifi y el puerto serie es a 115200 8N1 está invertido de modo que tenemos que pasarlo por un inversor o utilizar algo tipo el piratebus ...

ADS-B en OpenWRT

Esto es un experimento para recibir transmisiones ADS-B de aviones en routers corriendo OpenWrt con un pincho soportado por rtl-sdr (preferiblemente un RTL2832 con tuner R820T).

Esto es posible gracias a la implementacion dump1090 de antirez (https://github.com/antirez/dump1090) y el bajo uso de recursos de cpu que hace comparado con el software rtl_adsb que viene en el paquete de rtl-sdr ordinario.

En  un AR5387un con cpu mips broadcom 6328 BMIPS4350 con apenas 320 bogomips,  emplea alrededor de un 75-80 % de cpu...

Necesitamos además una antena apropiada para la banda de 1090 Mhz teniendo en cuenta que la recepción depende de que no hayan ningún obstáculo entre el emisor y el receptor.

Recomiendo la construcción de una colineal con coaxial de TV/SAT según las instrucciones siguientes: http://www.balarad.net/

Yo uso una de 12 elementos, midiendo unos 1.5 metros y detecciones a 150 km. (mi ubicación es muy mala).

Recompilamos OpenWrt para nuestro router, añadiendo los paquetes rtl-sdr y dump1090 como packages según:

1.- Creando los directorios trunk/packages/rtl-sdr y trunk/packages/dump1090

2.- Ponemos los makefiles siguientes en cada ruta: http://steve-m.de/projects/rtl-sdr/Makefile y https://www.dropbox.com/s/he5hj2rt0kisy20/Makefile

Seleccionamos los nuevos paquetes mediante un make menuconfig, junto al libusb-1.0 (dentro de Libraries) que lo requiere el rtl-usb  y recompilamos OpenWrt.

También podemos descargar los paquetes directamente e instalarlos con opkg:

https://www.dropbox.com/s/zjdad63o09iqmvu/dump1090_0.1.0-1_brcm63xx.ipk
https://www.dropbox.com/s/gxn11kc1c49uyhu/rtl-sdr_0.1.0-1_brcm63xx.ipk

Una vez instalado,arrancamos el dump1090 y tenemos que empezar a ver cosas como

root@OpenWrt:~# dump1090 --net --net-ro-port 47806

si arrancamos el planeplotter, configurando un receptor AVR TCP/IP a la ip del router con el puerto 47806 por ejemplo tendremos la ubicación de los aviones en tiempo real:

dump1090 --net --net-ro-port 47806 -raw

Podemos simulatear el modo servidor con modo interactivo en consola:

dump1090 --net --net-ro-port 47806 -raw --interactive

Tenemos pues un receptor de ADS-B de coste mínimo y con conexión wifi de tal modo que lo podemos dejar permanentemente lo más cerca posible de la antena y con el planeplotter compartir tráfico con flightradar24 por ejemplo. Esto hace viable además juntar los datos recibidos por varios equipos mediante dump1090 creando una red de receptores ADS-B.

Buena escucha!


PD: el firmware para el router Comtrend AR5387un ya preparado está aquí

FW OpenWrt Trunk ADS-B AR5387un

Versión ASL-26555_CL

Existe una versión de este router distribuida en Chile y otros países de América que difiere del ASL-26555_ES distribuido en España y que emplea un chip flash SPI 25FL064P de 8 MB (0x0800000) en vez del 25FL128P de 16 MB (0x1000000):

El particionado es diferente de modo que el firmware es específico:

[ 4.620000] Creating 8 MTD partitions on "spi0.0":
[ 4.630000] 0x000000000000-0x000000030000 : "uboot"

[ 4.750000] 0x000000050000-0x0000007e0000 : "linux"


 Pongo aquí los enlaces del firmware de ramdisk y flasheo adaptados:

Firmware ramdisk ASL 26556_C

Sysupgrade squashfs ASL 26556_C para flashear

(actualizados con extracción de eeprom y MAC de Wifi correcta)

El firmware se escribirá en la partición linux (tamaño 0x790000) una vez que hayamos arrancando con el firmware ramdisk mediante TFTP como explico para el ASL26555_ES con:


mtd -r write <nombre fichero> linux

Sacaremos copia antes de la partición linux desde el firmware RAM a un pendrive formateado en VFAT o EXT3/4 (montado en /mnt/sda1) mirando en /proc/mtd la partición asociada según:

dd if=/dev/mtdX of=/mnt/sda1/copia_linux.bin

Arrancando OpenWrt en ADB D.BG A4001N

Por fin arranca pero por ahora no fucionan el WIFI ni el puerto USB...
