Hi there, <div><br></div><div>I am wanting to use the ISDN cause code on an Asterisk 1.6 server to determine the status of a call attempt, where the call might not actually connect. Reason is I am checking for valid telephone numbers from a list of numbers, and I would like to know if the call has answered and cleared which I can by writing the hangupcause variable, but where I get an out of order network message, or number doesn't exist, I want to capture these ISDN cause codes where the call might not have connected and started the dialplan extension. </div>
<div><br></div><div>Is there any way to capture cause codes from calls that didn't connect?</div><div><br></div><div>Thanks</div><div><br></div><div>Steve Moran</div><div>Sydney, Australia</div>
