Automated Voice Call Reminders for Appointments
SchedulingKit uses Twilio's programmable voice API to deliver automated phone call reminders before appointments. Clients hear a professional recorded message with their appointment details and can press a key to confirm, reschedule, or connect to your office. Ideal for demographics that prefer phone calls over text messages.

Set up voice reminders with Twilio in just a few steps.
Connect Twilio voice
Enter your Twilio credentials and select a phone number for outbound reminder calls.
Record or generate voice messages
Upload a recorded message or use text-to-speech with your preferred voice. Include merge fields for appointment details.
Set call timing and retry rules
Schedule calls at 48 or 24 hours before appointments. Set retry logic: if no answer, retry once 2 hours later.

Callers press 1 to confirm, 2 to reschedule, or 3 to speak with a staff member. Responses update the booking status automatically.
Benefits
Why voice reminders with Twilio and SchedulingKit makes a difference.
Reach clients who do not read texts
Older demographics and clients without smartphones respond to voice calls at higher rates than SMS or email.
Keypad confirmation reduces no-shows
Interactive key-press confirmation gets clients to actively acknowledge the appointment, reducing no-shows by 30-45%.
Professional brand impression
A recorded voice message from your business sounds more personal than a text. Customizable voices and scripts match your brand tone.
Fallback to voicemail
If the client does not answer, Twilio leaves the reminder as a voicemail. The message still reaches the client even if they screen the call.
Voice Reminders in Practice
A real-world look at how Twilio voice reminders works with SchedulingKit.
A home healthcare agency coordinates 200 weekly in-home visits for elderly patients, with an average patient age of 74. Email open rates are 12% and SMS read rates are 65% for this demographic. The agency implements Twilio voice reminders through SchedulingKit to improve appointment adherence.
Each patient receives an automated call 24 hours before their visit: "Hello, this is a reminder from Sunrise Home Health. Your nurse, Jennifer, is scheduled to visit you tomorrow, Wednesday March 11th, at 10 AM. Press 1 to confirm, press 2 if you need to reschedule, or press 3 to speak with our office." The message is recorded by the agency's office manager in a warm, clear tone.
Of 200 weekly calls, 72% are answered live and 24% go to voicemail (the message is left automatically). Only 4% of calls fail to connect entirely. Among live answers, 85% press 1 to confirm, 8% press 2 to reschedule, and 7% press 3 to speak with staff. Before voice reminders, the agency experienced a 15% no-show rate for in-home visits, meaning caregivers drove to 30 empty homes per week. After implementation, the no-show rate dropped to 5%, saving an estimated 20 wasted trips per week.
At $35 per wasted trip (fuel, time, opportunity cost), the agency saves $700 weekly or $36,400 annually. Twilio voice calls cost approximately $0.014 per minute — a 2-minute reminder call costs $0.028. The 800 monthly calls total $22.40, delivering a 130x return on the messaging cost.
