**Follow these steps before installing**
A) Check that your card is being detected correctly:
lspci
Your should see something like this in case of HFC single port card, look for your case if different:
... 01:03.0 Network controller: Cologne Chip Designs GmbH ISDN network controller [HFC-PCI] (rev 02) ...
B) If you have a multi-port card unload these drivers:
vi /etc/sysconfig/zaptel
comment out (with # in the beginning of each line) all cards except ztdummy (just in case):
vi /etc/modprobe.d/blacklist:
add the following lines at the end:
blacklist hisax blacklist hisax_fcpcipnp blacklist hisax_isac blacklist crc_ccitt blacklist isdn blacklist slhc blacklist capi blacklist capifs blacklist kernelcapi blacklist kernel_capi blacklist avmfritz blacklist hfc4s8s_l1
... and restart your machine before anything.
C) The standard configurations generated by the command "isdn-init config" and those settings in "/etc/asterisk/misdn.conf" should work great with most cards but in some cases you should define according to your system configuration and ISDN telco specs among your own preferred ISDN behaviors with Asterisk.
==================================================
Trixbox 2.8.x - Asterisk 1.6.x only
==================================================
1. Install mISDN:
mISDN is installed by default in trixbox 2.8
Start with step 2 in the next section
If you have problems with showing card in asteriks (misdn show stacks)
You must install asterisk-chan_misdn, but before that you must crate a symbolic links
ln -s /usr/lib/libisdnnet.so /usr/lib/libisdnnet.so.0 ln -s /usr/lib/libmISDN.so /usr/lib/libmISDN.so.0 ln -s /usr/lib/libsuppserv.so /usr/lib/libsuppserv.so.0
Then
yum -y --enablerepo=trixboxbeta install asterisk-chan_misdn
==================================================
Trixbox 2.6.x - Asterisk 1.4.x only
==================================================
Tested until TB 1.4.19, but should do fine with latest versions
Addition: Using "yum upgrade" to ensure you're up to date may well give a more reliable outcome.
1. Install mISDN:
yum -y --enablerepo=trixboxbeta install asterisk-chan_misdn mISDNuser mISDN-modules mISDN
Addition: if the above fails due to dependencies, the following notes may help : misdn-installation-problem-dependencies-missing.
2. Install first the following (thanks to kostasics)
yum install bc yum install usbutils
Installing card (@ system level):
misdn-init scan misdn-init config (change this to PTP if you're not using MSNs as PTMP by default) misdn-init start (this command avoid restarting server in order to load card into system)
add it to your system boot:
chkconfig --add misdn-init
NOTE: If this command isn't working for you just add the following line to your rc.local:
vi /etc/rc.d/rc.local
and add before "/usr/sbin/amportal start" the following line:
misdn-init start
3. Copy the misdn sample file and edit for your ISDN line configuration (some options may differ from telcos)
cp /etc/asterisk-1.4.19_samples/misdn.conf /etc/asterisk/misdn.conf vi /etc/asterisk/misdn.conf
4. Restart asterisk and check status:
amportal restart asterisk -r misdn show stacks
You should see something like this:
BEGIN STACK_LIST: * Port 1 Type TE Prot. PMP L2Link DOWN L1Link:DOWN Blocked:0 Debug:0
==================================================
Trixbox 2.4.x - Asterisk 1.4.x only
==================================================
(Tested until TB 1.4.2, but should do fine with latest versions)
1. Install mISDN:
yum -y --enablerepo=trixboxbeta install asterisk-chan_misdn mISDNuser mISDN-modules mISDN
2. Installing card (@ system level):
misdn-init scan misdn-init config misdn-init start (this command avoid restarting server in order to load card into system)
add it to your system boot:
chkconfig --add misdn-init
NOTE: If this command isn't working for you just add the following line to your rc.local:
vi /etc/rc.d/rc.local
and add before "/usr/sbin/amportal start" the following line:
misdn-init start
3. Copy the misdn sample file and edit for your ISDN line configuration (some options may differ from telcos)
cp /etc/asterisk-1.4.17_samples/misdn.conf /etc/asterisk/misdn.conf vi /etc/asterisk/misdn.conf
4. Restart asterisk and check status:
amportal restart asterisk -r misdn show stacks
You should see something like this:
BEGIN STACK_LIST: * Port 1 Type TE Prot. PMP L2Link DOWN L1Link:DOWN Blocked:0 Debug:0
==================================================
Trixbox 2.2.x - Asterisk 1.2.x
==================================================
(Tested with TB 1.2.12, but should do fine with latest versions)
1. Install dependencies:
yum -y install kernel-smp-devel asterisk-devel spandsp-devel
If you got some error regarding to kernel-devel try this:
uname -r
mine shows:
2.6.9-34.0.2.ELsmp
Which means that my kernel is SMP, if yours is without smp at the end of line please install kernel-devel like this:
yum -y install kernel-devel
2. Installing mISDN and card (@ system level):
...installing packages:
wget http://www.beronet.com/downloads/install-misdn-mqueue.tar.gz tar xzf install-misdn-mqueue.tar.gz cd install-misdn-mqueue make install
..installing hardware:
misdn-init scan misdn-init config misdn-init start (this command avoid restarting server in order to load card into system)
add it to your system boot:
chkconfig --add misdn-init
NOTE: If this command isn't working for you just add the following line to your rc.local:
vi /etc/rc.d/rc.local
and add before "/usr/sbin/amportal start" the following line:
misdn-init start
3. Restart asterisk and check status:
amportal restart asterisk -r misdn show stacks
You should see something like this:
BEGIN STACK_LIST: * Port 1 Type TE Prot. PMP L2Link DOWN L1Link:DOWN Blocked:0 Debug:0
If you have any problem with load chan_misdn.so (Error: No such command "misdn show stack") in TrixBox 2.8, please try to create a symlinks.
Here is a way to that:
ln -s /usr/lib/libisdnnet.so /usr/lib/libisdnnet.so.0 ln -s /usr/lib/libmISDN.so /usr/lib/libmISDN.so.0 ln -s /usr/lib/libsuppserv.so /usr/lib/libsuppserv.so.0
Then restart asterisk
Use command "misdn show stacks"

If you have problem with incoming calls, try to add this code to "/etc/asterisk/misdn.conf"
[isdn] ports=1 context=from-pstn msns=*
Then restart...

Create a Custom Trunk with Custom Dial String like this:
mISDN/g:isdn/$OUTNUM$
(note that [isdn] group in config is being called here...)
