Product capabilities
What this channel handles
01
Voice OTP fallback
When an SMS code fails or stalls, the same API call can place a voice call that reads the code aloud. Verification completes instead of customers giving up.
02
Text to speech
Type your message and we convert it to natural speech. Record your own audio instead whenever you want a familiar voice.
03
Call campaigns at scale
Send one announcement to thousands of numbers with per-call reports: answered, missed, duration.
04
Per-minute billing
Connected calls are billed by the minute at the published voice rate. Unanswered calls are not billed.
05
Retry rules you control
Set how many times to retry unanswered calls and how long to wait between attempts.
