<div>I am trying to automatically detect disconnected numbers when using the outbound dialer I have written.</div>
<div> </div>
<div>* Some numbers hang up immediately with a Cause Code > 0 and no voice treatment</div>
<div>* Some numbers get voice treatment with a PROGRESS indication and an associated Cause Code > 0<br clear="all">* Some numbers get voice treatment with a PROGRESS indication and no associated cause code (CC=0)</div>
<div> </div>
<div>My application can pick up the PROGRESS indication (if I get one) and handle the hangup, but not if I don't get a cause code!</div>
<div> </div>
<div>Is there anything I can do to ensure that I always get a PROGRESS indication with cause code or a hangup with cause code? </div>
<div>Behaviour of the PRI seems to differ across telcos and also across numbers.</div>
<div> </div>
<div>I don't want to just assume hangup on PROGRESS indication as this may not be a disconnected number - it might be a forwarded or redirected number.</div>
<div> </div>
<div>I need to achieve consistency and this is proving very difficult. </div>
<div> </div>
<div>Has anyone else had this issue and if so, which tree should I be barking up?</div>
<div> </div>
<div>cheers,</div>
