First-call resolution

First-call resolution is when a caller's question or request is fully handled during their first call, with no need for a callback or follow-up to complete it.

First-call resolution is a common measure of service quality, because resolving an enquiry in one contact saves time for both the caller and the business and tends to leave callers more satisfied. Achieving it depends on the person or system having the information and ability to act on the spot. An AI receptionist can support this by answering common questions and booking appointments within the same call.
