Patent ID: 7948984

Claim:
A method for detecting an identifier change, comprising: automatically performing, by an apparatus on behalf of an agent at a call center, the steps of: dialing an identifier associated with an endpoint to initiate a call to the endpoint; detecting a network indicator indicating a change of the identifier; detecting a network message comprising a new identifier and status information associated with a user of the endpoint, wherein the status information indicates availability of the user to receive the call; determining the new identifier and the status information associated with the endpoint from the network message; determining, from the network message comprising the status information, a return policy for the user, wherein the return policy comprises a return date; updating a record to reflect the new identifier associated with the endpoint; determining a new recipient associated with the new identifier from the network message; updating the record to reflect the new recipient associated with the new identifier; comparing the new identifier to a list of identifiers designated not to call; determining whether to retry the call to the endpoint, wherein determining whether to retry the call comprises determining whether the new identifier is eligible to receive the call according to the status information, the comparison to the list of identifiers designated not to call, and the return policy; and dialing the new identifier associated with the endpoint if it is determined to retry the call and if it is determined that the new identifier is eligible to receive the call.
