Further info ...
So I ran the scenario with PRI DEBUG SPAN 1 and here is what
I can see:
** Call to a Good Number **
< Message type: CALL PROCEEDING (2)
< Channel ID (len= 5) [ Ext: 1  IntID: Implicit, PRI Spare:
0, Exclusive Dchan: 0
<                        ChanSel: Reserved

 etc etc etc

** Call to a Bad Number **
< Message type: CALL PROCEEDING (2)
< Channel ID (len= 5) [ Ext: 1  IntID: Implicit, PRI Spare:

    -- Channel 2, span 1 got hangup


As you can see, the PRI reports different stuff.  It also
has somewhere a 'Unallocated (unassigned) numnber (1).  Then
the PRI proceeds to send 'Inband information' which
presumably is the recording I am never hearing.
