ONE-TIME PASSWORD

Secure authentication with one-time passwords

Deliver one-time PINs (OTPs) through a voice message that’s read aloud when the call is answered. This ensures security, accessibility, and flexibility—perfect for users who need a reliable alternative to SMS.

Voice OTP

VOICE NOTIFICATION

Deliver critical updates with voice notifications

Ensure timely delivery of urgent alerts through voice calls, cutting through notification fatigue. Reach customers when it matters most, whether for appointment reminders, delivery updates, or emergency alerts.

Voice Message API

NUMBER MASKING

Protect privacy with number masking

Keep communications secure and anonymous in logistics and real-time delivery. A delivery driver can call a customer about a drop-off, or a ride-share driver can coordinate a pickup, all without exposing personal phone numbers—ensuring privacy, compliance, and trust.
