#trixbox

Hace algunos dias me pidieron instalar una tarjeta b410t de digium en un trixbox. en lo personal no me gusta trabajar con esta distribuccion, pero bueno, para quien lo necesite aqui les hago un pequeño HOW-TO ( como instalat digium B410 en trixbox) . Actualizado ya que hay mucho manuales que utiliza los antiguos paqutes de misdn que utilisan los comando tipo misdn-int, pero esto ya cambio por mISDN. Bueno a lo que vinimos, Primero actualizamos e instalamos lo necesario para compilar asterisk y zaptel.

yum update yum install bison bison-devel ncurses ncurses-devel zlib zlib-devel openssl \ openssl-devel gnutls-devel gcc gcc-c++ make kernel-devel yum install flex

Luego bajamos y descomprimos asterisk y zaptel acuerdate cambiar las X.X.X por la ultima version diponible. al hora de hacer este manual las versiones eran asterisk-1.4.21.2 y zaptel-1.4.11.

cd /usr/src/ wget http://downloads.digium.com/pub/asterisk/releases/asterisk-X.X.X.X.tar.gz wget http://downloads.digium.com/pub/zaptel/releases/zaptel-X.X.X.tar.gz tar -xzvf asterisk-X.X.X.X.tar.gz tar -xzvf zaptel-X.X.X.tar.gz

Compilamos zaptel con el soporte para b410 debes Tener internet en el instante ya que instalar el soporte mISDN y sus aplicativos.

cd zaptel-X.X.X ./configure make make install /etc/init.d/zaptel start make b410p

busca los dispositivos ISDN que tengas en tu server

/etc/init.d/mISDN scan

Configura estos dispositivos

/etc/init.d/mISDN config

corre los drivers de estos dispositivos. en este momento los led's del la tarjeta prenden y apagan, si esto no es asi puedes tener problemas de interrupciones en tu servidor.

/etc/init.d/mISDN start

lo único que falta es tener el canal de asterisk chan_misdn

cd /usr/src/asterisk-x.x.x make clean ./configure make cp channels/chan_misdn.so /usr/lib/asterisk/modules/ cp /usr/src/asterisk-1.4.21.2/configs/misdn.conf.sample /etc/asterisk/misdn.conf

Una vez realizado estos comandos, tendremos que editar el archivo /etc/asterisk/misdn.conf puedes utilizar este ejemplo:

[general] misdn_init=/etc/mISDN.conf debug=0 ntdebugflags=0 ntdebugfile=/var/log/misdn-nt.log ntkeepcalls=no bridging=no l1watcher_timeout=0 stop_tone_after_first_digit=yes append_digits2exten=yes dynamic_crypt=no crypt_prefix=** crypt_keys=test,muh [default] context=from-pstn language=en musicclass=default senddtmf=yes far_alerting=yes allowed_bearers=all nationalprefix=0 internationalprefix=00 rxgain=0 txgain=0 te_choose_channel=no pmp_l1_check=no reject_cause=16 need_more_infos=no nttimeout=no method=standard overlapdial=yes dialplan=0 localdialplan=0 cpndialplan=0 early_bconnect=yes incoming_early_audio=no nodialtone=no presentation=-1 screen=-1 echocancel=yes echotraining=no jitterbuffer=4000 jitterbuffer_upper_threshold=0 hdlc=no max_incoming=-1 max_outgoing=-1 [out] ports=1,2,3,4 context=from-pstn msns=*

ahora solo nos queda crear enlaces simbolicos en el rc para que arranquen los drviers antes que el asterisk.

ln -s /etc/init.d/mISDN /etc/rc5.d/S10mISDN ln -s /etc/init.d/mISDN /etc/rc3.d/S10mISDN ln -s /etc/init.d/mISDN /etc/rc4.d/S10mISDN ln -s /etc/init.d/mISDN /etc/rc2.d/S10mISDN

Para Configurar el FreePBX basta con crear una trncal CUSTOM. y Custom Dial String. Ponemos.

misdn/g:out/$OUTNUM$

Le projet consiste à la mise en place d'un serveur de téléphonie sur IP  avec trixbox  relié à un modem-routeur qui  permet à tout ordinateur connecté par wifi au modem routeur,doté d'un softphone puis enregistré au serveur de communiquer entre eux.

L’accès à distance  par internet via téléphone portable,ipad,pc aux cameras ip ou camera avec enregistreur.

Session Initiation Protocol (SIP) trunks allow existing VoIP-enabled business telephone systems to connect to the public telephone system over the Internet. A SIP trunk can handle many calls simultaneously using a single broadband Internet connection.

MBM's SIP trunks are commonly used to allow outbound calls to be made over the Internet which leaves existing telephone lines free for inbound calls. However, increasingly, customers are transferring (porting) their telephone numbers over to our SIP trunks so that they can also receive calls via the Internet as well as make calls. This means that expensive multi-channel ISDN lines can then be omitted altogether saving the organisation a considerable amount of money.

Our SIP trunks can support many different types of telephone numbers, region numbers, non-geographic numbers (0800, etc) and we can even offer international numbers from dozens of different countries.

Although SIP is the open standard for Internet phone calls, our service also supports the IAX proprietary standard used by Asterisk-based phone systems such as TrixBox.

I've found some tutorials describing how to install Trixbox on CF for Alix board (http://www.pcengines.ch/) using VMware server 1.0.x. Whenever I try to install it on physical CF my Windows XP does not recognized it as a "physicaldrive" and I can make my VMware working on Ubuntu using my karnel. Finally I decided to use other virtualization on Linux.

I installed the VirtualBox (http://www.virtualbox.org/wiki/Linux_Downloads) which worked very nice on my Ubuntu. Also download ISO image of TrixBox 2.6.x.x (http://fonality.com/trixbox/downloads)

Create a new VM:

New -> Name: trixbox_alix ;  Operating System: Linux ; Version: Linux 2.6 > Base Memory Size: 256MB > Boot Hard Disc -checked ; Create new hard Disk > Storage Type: Dynamically expending storage -checked > Location: [patch_where_you_want_to_keep_the_image_] ; Size: [depends_of_CF_card] 8GB [make_it_smaller_then_CF_-1GB]

VM settings:

Settings > System: Boot Order: CD/DVD-checked Hard Disk-checked > Storage: [in_IDE_controller_choose_the_location_of_trixbox_iso] > Audio: unchecked >  Network: [add_no._of_LANinterfaces_on_alix] ; Attached to: Bridged Adapter > Ports: add 2 USB and Serial Port

Now start the virtual machine and do the installation process. After installation go once more to setting and you have to unchecked the CD/DVD from Boot Order.

Then start the machine once more and let it finish the first boot. At the end of booting you will get the current IP address of your PBX.

Make the ssh to this machine and apply following changes:

edit /etc/grub.conf Comment out these 2 lines by putting a # at the beginning of the line: #splashimage=(hd0,0)/grub/splash.xpm.gz #hiddenmenu Add these 2 lines: serial --unit=0 --speed=9600 --word=8 --parity=no --stop=1 terminal --timeout=10 serial console And add this to the end of each line that begins with “kernel”: console=tty0 console=ttyS0,9600n8 (This tells Grub to direct console output to both the standard ttys (the ones you get with a keyboard and monitor) as well as the serial port (ttySx).)

Add this to the bottom of /etc/inittab: S0:12345:respawn:/sbin/agetty ttyS0 9600 linux (the “S0? is just a unique identifier; no two entries in inittab can start with the same thing. 12345 means all run levels (they correspond to /etc/rc2.d, rc3.d, etc) and respawn will ensure that it will accept another login after you log out.)

If you want to allow root to login over the console (versus logging in as a normal user and su-ing), add “ttyS0? to the bottom of /etc/securetty: echo ttyS0 >> /etc/securetty

edit /etc/sysconfig/init and change BOOTUP=color to BOOTUP=serial to prevent the graphical startup from blowing up your terminal.

If you have kudzu running (use chkconfig or look in /etc/rc3.d to see if it runs during boot): edit /etc/sysconfig/kudzu set SAFE=yes

OK so now you have to shutdown the machine and convert the virtualbox file system format to RAW. Go to location where you stored the image of your Trixbox and do the following command:

VBoxManage internalcommands converttoraw trixbox_alix.vdi trixbox_alix.img

After the conversion you have a RAW file which you can put on you CF card with the dd command. Plug you CF to your adapter and connect to PC. Find as which driver it is mounted and umount it and then copy the image:

dd if=trixbox_alix.img of=/dev/sdc

That's all, take out the card, put in your Alix and wait around 3min and it will be ready to use.

My trixbox image for 8GB card can be downloaded from here:
