Tester SS7 entre deux machines virtuelles avec Yate et TDMoE

Note: TDMoE utilise beaucoup de CPU, et ne transmet que 1000 fois / seconde. Cette configuration fonctionne mais la qualité audio est très mauvaise, et le CPU est à 100% pour un appel (environ 50% sans appel).

Testé avec:

  http://downloads.asterisk.org/pub/telephony/dahdi-linux/releases/dahdi-linux-2.6.1.tar.gz
  http://downloads.asterisk.org/pub/telephony/dahdi-tools/releases/dahdi-tools-2.6.1.tar.gz

mais des paquets Debian existent.

# Virtual Machines 10 and 11 (in my setup)
aptitude install linux-headers-amd64 linux-image-amd64 grub
# put grub on /dev/sda

See below for proper example.

# /etc/dahdi/system.conf
# Notice how we specify the _actual_ number of channels
# (24 for T1, 31 for E1)
# The MAC Address is the address of the remote (far) end.
dynamic=ethmf,eth0/52:54:00:00:00:11/0,31,0
# etc., see below.

modprobe dahdi
dahdi_cfg

Ma copie locale du code SVN http://stephane.shimaore.net/debian/src/yate-clean.tar.gz sinon

  svn checkout http://voip.null.ro/svn/yate/trunk yate

Compiler:

aptitude install sox libspandsp-dev

./autogen.sh
./configure
make

Start with

  sudo ./run -v

sudo est nécessaire pour l'accès aux ports DAHDI FIXME: comment modifier udev pour que ce ne soit pas nécessaire (creer un group “tdm” ou qqch comme ça)

Voir par exemple http://yate.null.ro/pmwiki/index.php?n=Main.Zapcard
