asterisk users - Apr 2008 - misdn, no free channels, similar to FAQ one

Hi,

Since a week ago I am trying to get chan_misdn working with asterisk
1.4.19, using HFC based ISDN card on Linux 2.6.22.

My setup is done as detailed on wiki and FAQ. 

* mISDN and miSDNusers are  1.1.7.2, unpacked, build and installed.
After installation and misdn-init, I have this:

aragorn:root/pts/1: # misdnportinfo  

Port  1: TE-mode BRI S/T interface line (for phone lines)
 -> Protocol: DSS1 (Euro ISDN)
 -> childcnt: 2
--------

mISDN_close: fid(3) isize(131072) inbuf(0x9846060) irp(0x9846060)
iend(0x9846060)

/etc/asterisk/misdn.conf has this group definition:

[extern]   
ports=1
context=misdn
msns=*

/etc/asterisk/extensions.conf has these contexts:

[default]
exten => 200,1,Dial(IAX2/duritji,,r)
exten => 201,1,Dial(IAX2/dragisha,,r)

exten => 202,1,misdn_check_l2l1(g:extern|2)
exten => 202,n,Dial(mISDN/g:extern/230210)

[misdn]
exten => _X,1,Dial(IAX2/duritji)
exten => _X,2,Hangup


IAX2 phones are locally configured/connected. Debug for misdn is set to
0x3

When I dial from outside, mu console (lots of -vvvvv's:) gives:

Asterisk Ready.

And, after some time:

If I dial  202 extension, I get:

Needless to say, my ISDN line is connected, and works.

What can be my problem here? Any1?

TIA,
