asterisk users - Apr 2009 - mISDN ports and dstchannel CDR logging

Hi All

I have noticed that when calling over mISDN channels the call itself is 
made over the channels listed in misdn.conf eg: 1,2,3,4 as misdn/1, 
misdn/2, misdn/3, misdn/4 etc.

However, when looking through the CDR's the call gets logged as misdn/0, 
misdn/1, misdn/2, misdn/3, misdn/4, misdn/5 etc.  I also noted that 
busy, failed, congested calls link mainly to misdn/0.  The only logic I 
can see is that the D channel is linked to misdn/0, but this is not 
always the case so it appears to be in error to me.  This is creating 
problems with our TMS as we bill based on route.

I am using asterisk 1.4.20 and misdn 1.1.8.  This never used to happen 
on asterisk 1.2.  I have also tried the latest chan_misdn on 1.4 with 
the exact same results.

I have found no other useful documentation on this.

Kind Regards
Garth
