How it works
Failed attempts have different causes—busy, unreachable, no answer or network error—and retry rules should use the actual outcome. Automated calls and verification flows start from events, rules or schedules. The system records their outcomes to determine subsequent actions.
Business example
A dialler distinguishes busy and no-answer results from a successfully connected conversation.
What to consider
Define retry limits, appropriate contact hours and no-answer handling. Check recipient-consent rules and protect one-time verification codes.
