Our carrier has the ability to block calls to numbers on the National DNC list. Every call that we send to the switch is checked against the DNC, and if a match is found the carrier returns a 503 (DNC Blocked).
Now, all of these 503s are set as an NA by Vicidial. So, naturally these numbers are dialed over and over, but blocked each time.
Is there a way to tell Vici that the "SIP Hangup Reason" (DNC Blocked) needs to be added as a DNC and not a NA?
