asterisk users - Nov 2005 - chan_misdn crashes : init_stack: success but entitylist not empty

Hi,

Asterisk 1.2 on FC4, all is right, I'm happy. But when I try to load
chan_misdn after a successful install, I get it :

# asterisk -vvvgc
[...]
 [chan_features.so] => (Feature Proxy Channel)
  == Registered channel type 'Feature' (Feature Proxy Channel Driver)
 [chan_misdn.so] => (Channel driver for mISDN Support (Bri/Pri))
  == Parsing '/etc/asterisk/misdn.conf': Found
Got: 1 from get_ports
Init. Stack on port:1
No Connect port:1
init_stack: Success
#

Nothing else. Asterisk crashes. If I look at /var/log/messages :

# tail /var/log/messages

Any idea ?... I've been on it for 1 whole week... I'm exhausted :-(

Cheers,

Yoann,
I am going through a similar problem you reported in a past posting:

Nov 24 17:49:31 ERROR[9326] chan_misdn.c: Unable to initialize mISDN
Nov 24 17:49:31 WARNING[9326] loader.c: chan_misdn.so: load_module
failed, returning -1
Nov 24 17:49:31 WARNING[9326] chan_misdn.c: cb_log called with
out-of-range port number! (0)
Nov 24 17:49:31 WARNING[9326] loader.c: Loading module chan_misdn.so failed!

How did you solve it?
Thanks,  jose

I looked back to this error. In fact, it happens when you forget to
initialize driver, so do it :

/etc/init.d/misdn-init scan

If everything goes well you can do :

/etc/init.d/misdn-init config
/etc/init.d/misdn-init start

Then, you can start asterisk :-)

Cheers,

YLB.
