OBD stands for Outbound, whereas IVR is the acronym for Interactive Voice Response. Typically, outbound solutions are used to provide information to customers using calls, SMS, or emails. IVR is an interactive recorded message to handle routine inquiries with self-service options where the customer uses the dial pad or voice instructions to give and receive information or navigate to the right agent. It is possible to combine IVR and Outbound service to interact with the customer and get their feedback.
