RECOMMENDED*– Operator may be associated with a key other than
0 *ALSO NOT RECOMMENDED*– Upside: Lower call transfer out volumes– Downside: Lower caller satisfaction

Zero Out Strategies• Example 2: “Super Serviceable”
– Zero out is enabled everywhere– Zero out is prominently advertised
• Main menu• First dialog state• Initial prompts
– Downside: Call volume coming out of the system– Upside: Caller satisfaction
• If you only have one call center group
– Downside: Caller dissatisfaction if they get to the wrong place and have to be transferred

– Zero out is strategically advertised• Places where caller appears to be having difficulty• Second and/or third reprompt• After caller has already done some self-service
– “Backoff” menu may be employed to route callers whose final destination is unclear.
