In order to install the b410p drivers one simply needs to type: `make b410p` The mISDN drivers will be downloaded and installed automatically. Then you will need to run `/etc/init.d/misdn-init config` and then configure the /etc/misdn-init.conf in accordance with your desired port configuration. You will then need to load the modules: `/etc/init.d/misdn-init start` For the Asterisk portion of the installation, you must use either the -trunk branch or the crichter branch (for a 1.2 based version of asterisk), which can be checked out as follows: `svn co http://svn.digium.com/svn/asterisk/team/crichter/0.3.0` The preferred and working branch right now is above is crichter. Trunk is not guaranteed to work. The remainder of the configuration is just setup of /etc/asterisk/misdn.conf.
