asterisk users - Nov 2006 - how to indicate an non-existent number?

Hello,

Using a PRI (E1) with the euroisdn protocol, I don't seem to get any 
specific message from the telco when attempting to dial a non-existent 
number. Asterisk returns a busy/congested code, but nothing indicating 
the number's real status.

How do you guys manage that issue? Do you record a message ("sorry, the 
number dialed can't be completed") and play it when the PRI or BRI 
returns a specific code? And what code is that?

Thanks in advance for any insight,

We check the value of HANGUPCAUSE.  DIALSTATUS is a VERY generic 
indication of the disposition of the call.

We check HANGUPCAUSE and playback messages we recorded depending on value.
Check http://networking.ringofsaturn.com/RemoteAccess/isdncausecodes.php or
google for q.931 cause codes or isdn cause codes.
