{{Note box|This has only be tested with a b410P card from Digium. It should be the same for other compatible hardware}}

Now you need to install the mISDN driver. You can use the following command:

Now you need to install the mISDN driver. You can use the following command:

  yum --enablerepo=smecontribs install misdn misdnuser misdn-kmdl-$(uname -r)

  yum --enablerepo=smecontribs install misdn misdnuser misdn-kmdl-$(uname -r)

For this to work you  may need to update your server (at least, you should have the latest kernel available)

  ln -s /etc/rc.d/init.d/e-smith-service /etc/rc6.d/K16mISDN

====Install the channel for asterisk====

===Install the channel for asterisk===

For asterisk to work with mISDN, it needs a channel (chan_misdn). For now, you need to take this package from [[ATrpms]] repository (in the future, this package should be imported in smecontribs)

  yum --enablerepo=atrpms install asterisk-misdn

  yum --enablerepo=atrpms install asterisk-misdn

This may also update asterisk, it shouldn't be a problem.

===Configure the channel===

Now, you can configure the channel. The config file is /etc/asterisk/misdn.conf

Most of the config should be OK (at least, it was for me, in France).

This will configure a group of ports (from 1 to 4). The name of this group is "trunks". Any calls comming from one of these ports will be processed from the from-trunk context (the default context for trunks in [[FreePBX]]

====Create a trunk in FreePBX====

===Create a trunk in FreePBX===

Now log into FreePBX admin interface in the server-manager, a create a new trunk, type "custom".

Enter the common information, like any other trunk (caller ID, max call etc...)
