Voice agents that schedule meetings through Cal.com
Connect AgentVoice to Cal.com and let your voice agents check availability, book meetings, and manage appointments during live phone calls. Your agents use Cal.com’s open scheduling infrastructure to find open slots across your team and confirm bookings before the caller hangs up.
Cal.com’s developer-friendly API and open-source architecture make this a natural fit for teams that want full control over their scheduling workflows. Your voice agent steps through the same booking process your Cal.com links use — checking event types, verifying availability, collecting attendee details, and creating the meeting — but does it all conversationally, without sending anyone to a link.
What your agent can do
During the call
- Fetch Available Slots — Query Cal.com for open time slots based on event type, team member, and date range to offer callers real options in real time.
- Handle Event Types — Support multiple meeting types — discovery calls, demos, consultations, follow-ups — each with their own duration, buffer, and availability rules.
- Confirm Time Zones — Verify the caller’s time zone and present availability in their local time so there’s no confusion when the invite arrives.
After the call
- Book Meetings — Create confirmed bookings through Cal.com’s API with attendee name, email, meeting type, and any custom fields your event type requires.
- Trigger Notifications — Cal.com handles confirmation emails, calendar invites, and any workflow automations you’ve configured — reminders, SMS confirmations, or webhook triggers.
- Add Meeting Notes — Attach conversation context, caller requirements, and preparation notes to the booking so your team shows up informed.
- Reschedule Bookings — Handle rescheduling requests by finding a new available slot and updating the existing Cal.com booking.
Use Cases
Inbound Lead-to-Meeting
- Voice agent qualifies inbound callers and immediately books a meeting with the right team member through Cal.com
- Caller gets confirmed on the spot — no scheduling link to open later, no follow-up email to wait for
- Cal.com sends the calendar invite and any configured reminders automatically after the booking is created
Multi-Event-Type Routing
- Agent determines what the caller needs — sales demo, technical consultation, support call — and selects the right Cal.com event type
- Each event type has its own availability rules, duration, and team assignment, so the booking matches the request
- Callers who need a 15-minute intro get different slots than those booking a 60-minute deep dive, all handled automatically
Team Round-Robin Scheduling
- Agent books meetings using Cal.com’s round-robin event types, distributing appointments fairly across your team
- Availability is checked across all team members assigned to the event type, and the caller gets the first available slot
- Each team member’s calendar stays balanced, and the caller always gets a confirmed time with a specific person
