Which AUX code is used to complete case notes once a call is finished?

The AUX code used to complete case notes once a call is finished is ACW, which stands for After Call Work. This code is specifically designated for agents to focus on documenting and completing any necessary follow-up actions related to a call after it has concluded. During this period, agents can ensure that all relevant details are accurately recorded, customer issues are addressed, and any action items are noted, enhancing the quality and continuity of customer service. After Call Work is an essential part of the process as it allows for thorough case notes, which are crucial for future interactions and maintaining customer satisfaction.

The other codes, while relevant in various contexts, serve different purposes. For instance, FON typically refers to a code used for indicating a phone call is in progress. WBR is often used to signify breaks or non-working status, and END may denote the termination of an interaction but does not specifically imply the action of completing case notes. Thus, ACW is the most appropriate and accurate choice for this scenario.
