When an agent is involved in an outbound dialing campaign and needs to transfer a call to another agent while also passing interaction information, the most appropriate method is to use the Notes section in Genesys Cloud CX. The Notes section allows agents to input relevant details about the interaction, which can then be viewed by the next agent handling the call. This is a simple and efficient way to pass context between agents during a transfer. Options A and B involve updating customer data, but this is not the most direct or recommended method for passing interaction-specific information during a transfer.
