Make an outbound phone call using one of your AI voice agents. The agent handles the conversation automatically based on its prompt and configuration.

​
Configuration

​
How follow-ups work

When a call results in no-answer or voicemail, the configured behavior determines what happens next:
  • None — The workflow stops at this step. No retry, no next step.
  • Retry — The workflow schedules another call after the follow-up delay. This repeats up to the max follow-ups limit.
  • Continue — The workflow skips the retry and moves to the next action in the flow.
Follow-ups respect calling days and hours. If a retry is scheduled outside the calling window, it’s deferred to the next available time.

​
Calling window and contact timezone

Calling days and hours are evaluated in the contact’s timezone, not your workspace timezone — so a 9 AM – 8 PM window means 9 AM – 8 PM where the contact is. Nedzo resolves the timezone from the contact’s phone number. If it can’t determine one, the call is not placed — it’s held rather than dialed against a UTC guess, which is what previously produced calls in the middle of the night. To fix a held contact, set its timezone on the contact record or correct the phone number.

​
Output

After the call completes, the following data is available to subsequent steps:
successEvaluation and dataExtracted require the corresponding features to be enabled on the agent’s Settings > Conversation Analysis tab. callDisposition replaces the previous “Call Outcome” output field.

Examples

Outreach with follow-up:
  1. Action: Voice call with sales agent
    • No-answer: Retry after 4 hours
    • Voicemail: Continue to next step
    • Max follow-ups: 3
    • Calling hours: 9 AM – 6 PM
    • Calling days: Mon–Fri
  2. Action: Send SMS — “Hi {{firstName}}, I tried to reach you. Let me know a good time to chat.”
Branch on success evaluation:
  1. Action: Voice call with qualification agent
  2. Action: Condition — Check successEvaluation
    • Path: pass → Send follow-up email with next steps
    • Path: fail → Add “needs-review” tag to contact

​
Timeout

Voice calls have a 5-minute timeout by default. If the call hasn’t connected within that time, it’s marked as failed.
