Abstract
A call handler is configured to originate calls using records stored in a contact list by using various campaign call data comprising a set of calling party numbers or 'ANIs' that are to be used when originating calls. Each ANI is associated with a status, which reflects whether a terminating voice service provider has blocked a prior call using that ANI. The call handler is configured to recognize when a call is blocked by examining SIP protocol-based error codes and/or intercept announcements provided by the carrier when the call is blocked. Upon detecting the call is blocked, the call handler will update the status of that ANI and select another ANI value from the campaign call data to use for subsequent call originations of that campaign. A set of ANIs that a carrier has blocked may be stored to facilitate subsequent redress with that carrier.
