These are two service console features that work together to improve the process of making a phone call to the customer based on the case notes. Macros are tools that allow agents to automate common or repetitive tasks on a record, such as sending an email or updating a field. Macros can help agents save time and avoid errors when making a phone call to the customer. History Utility is a tool that allows agents to view their recently accessed records or tabs in the service console. History Utility can help agents quickly return to a prior case and find the phone number in the case notes.
