AI appointment setter that keeps your calendar full
CallUltra books and reschedules appointments in real time, syncs straight to your calendar, and fills open slots automatically, so your team spends more time in meetings, and less time chasing them.
Where appointment setting falls apart
Booking by hand is slow, and every gap in the process costs you a meeting.
Every appointment booked, rescheduled, and refilled without your team lifting a finger. CallUltra calls leads the moment they’re ready, offers open times from your live calendar, and locks in the meeting, so your schedule stays full on its own.
Why teams hand booking to CallUltra
Fill your calendar automatically and get your team out of scheduling.
Instant booking
The agent confirms and schedules in real time, with no endless back and forth to find a slot.

Real-time rescheduling
Calendar sync means when a slot changes, a new one is booked on the spot, so no gaps open up.

Optimize for bookings
Leads lock in a time at the moment of interest, before they drift away and go cold.

Less chasing, more meeting
Your team shows up to meetings instead of chasing people to attend them.

Everything you need to book at scale
One agent to reach, qualify, schedule, and refill, all synced to your calendar.
Live calendar booking
CallUltra offers open times from your real calendar and books the meeting during the call, so availability is always current.

Instant slot refill
When someone cancels, the agent automatically reaches the next lead and fills the slot, so a cancellation doesn’t cost you the hour.

Speed to lead
The agent calls a new lead within seconds of a form fill or trigger and books them while intent is high.

Real-time CRM and calendar sync
Every booking reads and writes to your CRM and scheduling tools live, so records stay accurate without manual entry.

White-glove partnership
A dedicated Success Manager builds your booking scripts, applies proven best practices, and keeps optimizing the flow with you, on every plan.
