1.2 What is Asterisk:
The Definition of Asterisk is described as follow:
Asterisk is a complete PBX in software. It runs on Linux, BSD, Windows (emulated)
and provides all of the features you would expect from a PBX and more. Asterisk does
voice over IP in four protocols, and can interoperate with almost all standards-based
telephony equipment using relatively inexpensive hardware.
Figure 1: Asterisk_OpenVox Setup

3. Software Installation and Configuration
A810P/AE810P supports dahdi software device driver on Linux. To use
A810P/AE810P, user must download, edit, install and configure dahdi and
asterisk.
3.1 Download asterisk, dahdi, driver and firmware
1. Download asterisk from www.asterisk.org
Right here, take asterisk-1.8.0 for an example:
http://downloads.asterisk.org/pub/telephony/asterisk/releases/asterisk-1.8.0.tar.gz
2. There are two methods to download dahdi source.
1) Download dahdi from openvox website, which has included driver of
A810P/AE810P, user doesn’t need to modify any files.
http://downloads.openvox.cn/pub/drivers/dahdi-linux-complete/openvox_dahdi-lin
ux-complete-current.tar.gz (if you select this method, just skip to step 3.3 after
you finish this step)
2) Download dahdi from asterisk official website: downloads.asterisk.org, then
user needs to download the driver patch of A810/AE810 as well. The patch is
located here:
http://downloads.openvox.cn/pub/drivers/dahdi-patches/a2410p/opvxa24xx_dahd
i-linux.tar.gz
There is a directory named opvxa24xx after you untar this package , please copy
the whole directory to /usr/src/dahdi-linux-xxx/drivers/dahdi/. And you have to
modify some configure files before you start compiling dahdi.
3.2 Modify the configure files
There are some steps here, make sure you have already modified them before
you compile dahdi.
A. Forward to directory /usr/src/dadhi-linux-xxx/build_tools, and modify file
live_dahdi like this:
Figure 3: live_dahdi screenshot
B. Forward to directory /usr/src/dahdi-linux-xxx/drivers/dahdi, and modify file
Kbuild like this:

Figure 4: Kbuild screenshot
C. Forward to directory /usr/src/dahdi-linux-xxx/drivers/dahdi, and insert the
following info in the red circle into the file Kconfig near line 156.
Figure 5: Kconfig screenshot
D. Forward to directory
/usr/src/dahdi-tools-xxx/xpp/perl_modles/Dahdi/Hardware, and add the
following info to the file PCI.pm.
Figure 6: PCI.pm screenshot
E. Forward to directory /usr/src/dahdi-tools-xxx/xpp/perl_modules/Dahid, and
modify file Chans.pm like this:
Figure 7: Chans.pm screenshot
F. Forward to directory /usr/src/dahdi-tools-xxx, and add the following info to file

modules.sample.
Figure 8: modules.sample screenshot
G. Forward to directory /usr/src/dahdi-tools-xxx, and modify blacklist.sample like
this:
Figure 9: blacklist.sample screenshot
Note: If you select CentOS 5.6 you have to patch dahdi, please see here for the
patch.
3.3 Installation
Before installing dahdi and asterisk, please make sure that some supporting
packages have been installed.
Note that if there is no kernel source in the system, user should install it. User
can run yum again: yum install kernel-devel .
It is time to check for the availability of some supporting packages:
rpm -q bison
rpm -q bison-devel
rpm -q ncurses
rpm -q ncurses-devel
rpm -q zlib
rpm -q zlib-devel
rpm -q openssl
rpm -q openssl-devel
rpm -q gnutls-devel
rpm -q gcc // make sure the version is higher than 4.0
rpm -q gcc-c++
rpm –q libxml2
If any of those packages are not installed, please install them by using yum.
yum install bison
yum install bison-devel
yum install ncurses
yum install ncurses-devel

yum install zlib
yum install zlib-devel
yum install openssl
yum install openssl-devel
yum install gnutls-devel
yum install gcc
yum install gcc-c++
yum install libxml2
User can install the driver via the following steps (assuming user has the source
code of dahdi device driver installed in /usr/src/dahdi-2.2.XX directory):
1. Checking the A810P/AE810P hardware by command: lspci –vvvvv
From the following, user can see that there is a device called communication
controller interface be found.
Figure 10: hardware detect
2. Compiling and installing dahdi
1) a. If user uses dahdi-linux-complete-xxx. tar.gz, execute these commands:
cd /usr/src/
tar –xvzf dahdi-linux-complete-xxx.tar.gz
cd dahdi-linux-complete-xxx
make
make install
make config
b. If user uses dahdi-linux-xxx.tar.gz and dahdi-tools-xxx.tar.gz, execute these
commands: (make sure you have already finished step 3.2 before you carry
out the following commands).
cd /usr/src
tar –xvzf dahdi-linux-xxx.tar.gz
cd dahdi-linux-xxx,
make
make install
cd /usr/src/
tar –xzvf dahdi-tools-xxx.tar.gz
cd dahdi-tools-xxx,
./configure

3.4 Configure
1. Loading modules for opvxa24xx:
modprobe dahdi
modprobe opvxa24xx opermode=YOUR COUNTRY //the driver name is the same
as //opvxa24xx
openvox_dahdi-linux-complete 2.2.0 or higher versions allows user to adjust how
long to initiate once IRQ. User is able to adjust time to initiate IRQ by the following
way:
modprobe opvxa24xx opermode=YOUR COUNTRY ms_per_irq=2
ms_per_irq=2 means every 2 millisecond initiate once IRQ.
The valid values of ms_per_irq are 1,2,4,8,16, the default value is 1.
dahdi-linux-complete-2.4.0 or higher version supports this function.
Execute dmesg command to check if you have made the EC module worked.
If user uses AE810P/AE810E, from figure 11 below, user will be able to see EC
module has been detected by the
system.

2. Checking the configure files
Run the command vi /etc/dahdi/genconf_parameters to disable the softecho
parameter.
If users use AE810P, please set echo_can to none as following:
echo_can none
If users use A810P, just ignore that step above.
Then run these commands:
dahdi_genconf
dahdi_cfg –vvvv
The output might be the same as the following:

Figure 12: dahdi_cfg –vvvv screenshot
The command dahdi_genconf will automatically generate the system.conf under
directory /etc/dahdi and dahdi-channels.conf under /etc/asterisk. Please check the
setting of system.conf, it looks like the following:

User Manual

Figure 13: system.conf
In order to match your country pattern, you will need to change the parameters
load zone and default zone to your country. For example, your system is in
CHINA, then, you will change their value like this:
loadzone = cn
defaultzone = cn
Meanwhile, you also need to modify another parameter: country in file
/etc/asterisk/indications.conf
Figure 14: indications.conf
After loading dahdi and opvxa24xx driver, user should check the chan_dahdi.conf
and dahdi-channels.conf under /etc/asterisk. Please make sure
dahdi-channels.conf has been included into chan_dahdi.conf. If not, run the
command:
echo "#include dahdi-channels.conf" >> /etc/asterisk/chan_dahdi.conf
Make sure that the context in dahdi-channels.conf should exist in extensions.conf.
File dahdi-channels.conf should look like as the following:
FXO ports use FXS signaling, the configure file looks like this:

FXS ports use FXO signalling, the configure file looks like this:
Figure 15: dahdi-channels.conf
3. Starting asterisk and test calls
Checking the dahdi channel loading from asterisk console:
asterisk –vvvvvvvgc
Entering asterisk console, run command: dahdi show channels . If dahdi channels
can be shown, which means the dahdi channels have been loaded into asterisk.

Figure 16: dahdi show channels
When user makes an inbound call, CLI will show as the following:
Figure 17: inbound call
When user makes an outbound call, CLI will show as the following:
Figure 18: outbound call
The status of channel looks like the following. If user uses AE810P, EC Status of
active channel should be ON; otherwise it would be OFF.

Notes:
User can use command cat /proc/interrupts to confirm A810P/AE810P has
independent IRQ. If A810P/AE810P shares IRQ with other device. To avoid IRQ
conflict, A810P/AE810P enable user to adjust pin number when update firmware,
please refer this manual for more details.
