DAHDI Linux and Tools

DAHDI Linux version 2.3.0.1 needs to be installed. I installed the latest version of dahdi-tools at the time of writing. Make sure you install LibPRI first as you still need this library.

The main difference when configuring your span is instead of using span you will use dynamic.

dynamic=ethmf,em3/00:50:C2:65:DC:82/0,31,0

• ethmf is the interface used. Redfone specific
• em3 is the interface on my Linux system that will be communicating with Redfone device. The device has a default IP of 192.168.1.254. If the device is dual span capable then it will have a second IP of 192.168.1.253. Configure the NIC with a 192.168.1.x/24 IP address so it can communicate with the device
• 00:50:C2:65:DC:82 is the MAC address of the network card in your Linux system that will be communicating with the Redfone device.
• 0 I’m not sure what this is. I think if you have more than 1 span it will be the span that you want to use.
• 31 is the number of channels that the span is capable of. T1 is 24 and E1 is 31. If you are only use 10 channels still enter the number that the T1/E1 is capable of.
• 0 is the timing.

An example of my /etc/dahdi/system.conf file is:

dynamic=ethmf,em3/00:50:C2:65:DC:82/0,31,0
bchan=1-10
dchan=16
mulaw=1-10

fonulator prerequisites

For simplicity I use rpmforge otherwise you will have to source the following packages as they are not include in the distribution.

install rpmforge

rpm -Uhv http://pkgs.repoforge.org/rpmforge-release/rpmforge-release-0.5.2-2.el6.rf.x86_64.rpm

prerequisites

yum -y install libpcap libpcap-devel libnet 

argtable

Argtable is part of rpmforge but for some reason I could not get fonulator to accept this version of argtable so I used the version from redfone.

wget http://support.red-fone.com/downloads/tools/argtable2/argtable2-8.tar.gz
tar -xvf argtable2-8.tar.gz
cd argtable2-8
./configure
make
make install

If you are using a 64 bit distribution then I had to copy the libargtable2* files to /usr/lib/ as when I went to build fonulator it could not find the files even though they were installed.

scp /usr/local/lib/libargtable2* /usr/lib/

install libfb

wget http://support.red-fone.com/downloads/fonulator/libfb-2.0.2.tar.gz
tar -xvf libfb-2.0.2.tar.gz
cd libfb-2.0.2
./configure
make
make install

install fonulator

wget http://support.red-fone.com/downloads/fonulator/fonulator-2.0.3.tar.gz
tar -xvf fonulator-2.0.3.tar.gz
cd fonulator-2.0.3
./configure
make
make install

download redfone.conf

cd /etc
wget http://support.red-fone.com/downloads/fonulator/redfone.conf

Edit /etc/redfone.conf

Enter the servers MAC address into server= remark span 2, 3 and 4.

Here is an example of my file.

[globals]
fb=192.168.1.254
port=1
# Which Asterisk server destination MAC address for TDMoE Traffic?
server=D4:BE:D9:EF:F8:FD

# Determines which span is to derive timing from telco
priorities=0,1,2,3
#
# E1 PRI SPAN WITH CRC4
[span1]
framing=ccs
encoding=hdb3
crc4

= test fonulator

Firstly execute fonulator

fonulator

Secondaly view the config as seen by fonulator

fonulator -vq
