Of those calls ended as a booked appointment (booking-outcome calls)
A booking-outcome call is a call that ended as a scheduled appointment in Cleo’s call log. It is not a completed appointment and it is not revenue: Cleo does not report whether customers arrived or what work was paid for. Booked appointments and transfers are separate outcomes, not a breakdown of the answered calls. These are one dealership’s results, not a promise of yours.
El Cerrito Honda, in a separate 30 days: 633 calls answered and 112 appointments booked, 34 of them while the dealership was closed.

What to compare
Three checks before you pick a phone agent.
01 · After hours and overflow
Check the hours it answers, how fast it picks up, and whether it covers nights, weekends and the moments your BDC is busy. Test each vendor after hours and at your busiest time of day, and note which calls end in a booking.
02 · Booking into your scheduler
Confirm which scheduling system it books into, whether it checks open times before offering one, and what it says when no time is available or a booking fails. A message taken is not an appointment.
03 · Handoff and setup time
Ask where calls go when a person is needed: a transfer, a callback task for your team, or nothing. Then ask who does the setup and how long until it answers real calls, and get the answer in writing.
Count outcomes the same way for every vendor. An answered call is not a booking, and a booked appointment is not a completed visit.
Before you sign
Questions to ask every vendor, Cleo included.
Ask for the same numbers
Ask each vendor for calls answered, appointments booked and after-hours bookings from one real dealership over the same 30 days, and for how it counts a booked appointment. Compare like with like.
Check the term and the exit
Ask what the contract term is, what you can export if you leave, and how locations are added. Confirm your scheduler connection and service rules before launch.
