asterisk users - Dec 2005 - mISDN & chan_misdn on Fedora Core 4 - problems

Hi Everyone,

I'm trying to get chan_misdn working with asterisk.  Currently I'm using
two seperate * boxes with chan_capi and one AVM Fritz card per box and 
I'd love to get one box doing the job (plus I'm hoping that echo 
cancellation is better in chan_misdn).

I have this error when I start asterisk with chan_misdn configured: -
[chan_misdn.so] => (Channel driver for mISDN Support (Bri/Pri))
mISDN_close: fid(8) isize(131072) inbuf(0xb7dae008) irp(0xb7dae008) 
iend(0xb7dae008)
  == Parsing '/etc/asterisk/misdn.conf': Found
P[ 0] Got: 1 from get_ports
Segmentation fault (core dumped)


So far I've managed to do this:

Install the 2.6.14.3 kernel

Install the mISDN kernel patches and compile the kernel with the latest 
mISDN (via make menuconfig, etc)

Compile and install the latest CVS "mqueue" mISDN and mISDN code (only
the mqueue release seemed to work with GCC-4 which comes with Fedora Core 4)

Compile and install the latest CVS chan_misdn and install it

Loaded the mISDN modules (nice stuff showing in dmesg), did the 
/etc/rc.d/init.d/misdn-init start (after the config argument)  and did 
the funny "mkdir -p /dev/capi", "mount /dev/capi" after
defining the
capifs stuff in fstab.  I haven't a clue what I'm doing here with capifs
- beats me!

I did get an error after I ran the "misdn-init start" - its says
"FATAL:
Error inserting mISDN_dsp (/lib/modules/2.6.14.3/extra/mISDN_dsp.ko): 
Unknown symbol in module, or unknown parameter (see dmesg)".  I don't 
know why I'm getting this error because everything was installed with 
this kernel - no old stuff lying around I think.

When I start asterisk with asterisk -vvvgc I get the text and the 
segmentation fault as above.

Anyone any ideas?  (apart from go buy other hardware :).

Thanks very much!

Derek

I've yet to get mISDN + chan_misdn (or even mISDN + chan_capi-cm) to 
work. My advice is to stick with CAPI+chan_capi-cm. :) No matter how I 
compiled chan_misdn, Asterisk would always segfault on startup (on both 
my Gentoo test box and my RHEL4 production box). For the AVM!Fritz card, 
I recommend stock CAPI and chan_capi-cm for stability.

I'm currently using an Eicon Diva Server V-4BRI with chan_capi-cm and 
the results are great. I highly recommend the card.

cYa,
Avi
