[asterisk-users] PRI cause codes

[Steve Casto]

I am trying to retrieve the cause code of a outgoing call over a PRI 
where the number called is out of service. When an out service number is 
called I get  a recording that the number dialed is not a working 
number. I see cause code 1 in in the CLI as soon as the call is dialed 
the Telco recording goes on for 30 sec. then hangs up. Any idea on how 
retrieve info that the called number is is out of service. My 
understanding is cause code 1 is an  unallocated number.
thanks
