I don't use Fedora, but it seems those that do have had problems loading the drivers. Try the modprobe wcfxo then zaptel, then check your /proc/interrupts. If that doesn't work, try modprobe zaptel only. I think someone mentioned a readme in the src/zaptel directory for Fedora as well. Might look. _______________________________________________ Asterisk-Users mailing list Asterisk-Users@lists.digium.com http://lists.digium.com/mailman/listinfo/asterisk-users To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
