This gives callers options that allow calls to be handled quicker and more effectively. The options available are almost limitless. Callers hear an up-front greeting, which often includes office hours, and are given choices to help “guide” their call. These choices, depending on your needs, may result in different actions. Pressing 0 might bring the caller to a CSR to take an order, pressing 1 might patch the caller to your customer service department, pressing 2 might send the caller to voicemail, etc.
