[Freeswitch-users] ft_mod_misdn: Failed to bind mISDN socket [0:1]: Device or resource busy

Hi! I got on my machine a 4 port ISDN board, which I'd love to use with my FS machine. I followed this guide, one of your developers Stefan Knoblich, had written once. I followed this guide: http://lists.freeswitch.org/pipermail/freeswitch-users/2012-June/084633.html but I am not getting really smart. Somewhere in the output I see the error message: http://pastebin.com/YucJ7rPf Failed to bind mISDN socket [0:1]: Device or resource busy Is somebody of you guys familiar with mISDN with freeswitch ?! Or do you advise that I should keep the fingers away, and switch to asterisk to make use of ISDN with a pbx ?! if you guys have any ideas, would be cool! Doug
