An accurate determination of the disposition of a call origination is made in a contact center by mapping Session Initiated Protocol cause codes to reflect whether a call attempt was made to a remote party. Certain cause codes reflect various conditions where a call may originate from a contact center, but for various reasons, was not offered to the remote party, or more specifically, to an interface associated with the telephone number of the remote party. Reflecting these calls as incomplete calls, as opposed to call attempts, allows the contact center to more accurately reflect the number of call attempts. Accurately tracking the number of call attempts is important to comply with various state and federal regulations regulating the number of call attempts during a given time period. Further, incomplete calls may be symptomatic of a facility failure requiring attention, causing an administrator to be alerted.
