Has anyone got chan_misdn working with passive BRI cards yet? I've tried both hfc (hfcpci.ko) and w6692 (w6692pci.ko) cards, but when I start asterisk I get the following when chan_misdn is loaded: [chan_misdn.so] => (Channel driver for mISDN Support (Bri/Pri)) == Parsing '/etc/asterisk/misdn.conf': Found == Registered channel type 'mISDN' (This driver enables the asterisk to use hardware which is supported by the new ) == Registered application 'misdn_set_opt' debug_init: using stdout for debug log debug_init: using stderr for warning log debug_init: using stderr for error log debug_init: debug_mask = 0 Init. Stack on port:1 TE Stack No Upper ID port:1 init_stack: Success Ouch ... error while writing audio data: : Broken pipe After all the effort of recompiling my kernel (2.6.11 and 2.6.8) for misdn I'd really like to get asterisk working with misdn.
