Ici nous allons installer une carte T2 Sangoma dans un serveur linux Debian:

Liste des packages nécessaires:

apt-get -y install build-essential
apt-get -y install gcc
apt-get -y install g++
apt-get -y install automake
apt-get -y install autoconf
apt-get -y install libtool
apt-get -y install make
apt-get -y install libncurses5-dev

apt-get -y install linux-source-$(uname -r)
apt-get -y install linux-headers-$(uname -r)
apt-get -y install libsctp-dev
apt-get -y install libtool

Téléchargeons les logiciels WANPIPE livrés par Sangoma, DAHDI (channel) et LIBPRI ( gestion des protocoles Q931 et Q921) livrés dans les sources de Asterisk par DIGIUM

wget http://downloads.asterisk.org/pub/telephony/dahdi-linux-complete/releases/${DA}.tar.gz
wget http://downloads.asterisk.org/pub/telephony/libpri/releases/${PRI}.tar.gz
wget ftp://ftp.sangoma.com/linux/current_wanpipe/${WAN}.tgz

La compilation se poursuit respectivement par:

make all && make install & make config
make && make install
./Setup dahdi

Asterisk prend en compte la carte gràce au fichier /etc/asterisk/chan_dahdi.conf:

;;Sangoma A102 port 1 [slot:5 bus:0 span: 1]
switchtype=euroisdn
context=isdn-in
group=1
signalling=pri_cpe
channel => 1-15,17-31

;;Sangoma A102 port 2
switchtype=euroisdn
context=isdn-in
group=1
;group=2
signalling=pri_cpe
channel => 32-46,48-62
