Technology to respond to a termination reason of an accounting record via an improved charging component is disclosed. The disclosed subject matter can be backwards compatible to support responding to a conventional SIP ‘BYE’ method and a conventional SIP ‘CANCEL’ method. Additionally, the disclosed subject matter can respond to other SIP methods, empty reason-headers, etc. In an aspect, a reason-header can be forced into an accounting record based on received session termination information. In an embodiment, the reason-header can be determined to satisfy a rule related to acceptable reason-headers. Where the rule is determined to be unsatisfied, a query can be generated toward a device that supported the now terminated communication, wherein a response to the query can comprise another reason-header that can be determined to satisfy the rule. The accounting record can be updated based on the other reason-header and employed in generating a charging data record that can alter corresponding billing.
