Hi all,

I'm trying to get misdn/Asterisk/Freepbx running inside a virtualized Debian etch machine, and everything looks pretty fine so far, however Asterisk reports all channels being busy when trying to dial out. Could someone help me how to debug this problem?

asterisk:~# uname -r
2.6.18-4-xen-686

asterisk:~# lspci -v
00:00.0 Network controller: Cologne Chip Designs GmbH ISDN network controller [HFC-PCI] (rev 02)
        Subsystem: Cologne Chip Designs GmbH ISDN Board
        Flags: bus master, medium devsel, latency 16, IRQ 18
        I/O ports at ac00 [disabled] [size=8]
        Memory at ff6ffc00 (32-bit, non-prefetchable) [size=256]
        Capabilities: [40] Power Management version 1

asterisk:~# misdn-init scan
[OK] found the following devices:
card=1,hfcpci
[ii] run "/usr/sbin/misdn-init config" to store this information to / etc/misdn-init.conf

asterisk:~# misdn-init config
[OK] /etc/misdn-init.conf created. It's now safe to run "/usr/sbin/ misdn-init start" [ii] make your port (1) available in asterisk by editing "/etc/ asterisk/misdn.conf"

asterisk:~# misdn-init start

I'm a bit unsure about the last stance here but documentation is pretty sparse.

I have a suspiciously looking error in my syslog as well:

Jul  4 05:45:15 asterisk kernel: MDL_ERROR|REQ (tei_l2)

when restarting Asterisk. I've also explicitly unloaded the hisax module, re-init-ed msidn, restarted Asterisk: same error.

Many thanks!
