Calling windows and retries

The schedule step of an outbound campaign: dates, daily call hours, days of the week, timezone, and how many times to call back a number that did not answer.

Voice agents

The second step of the outbound wizard, Set when the campaign runs and how retries behave, decides when a contact’s phone is allowed to ring. Everything on it can be changed later in the Schedule section of the campaign’s Settings page, while the campaign is paused.

Fields

Field	Default	Notes
Start Date	Today	The first day calls may go out. A future date leaves the campaign `scheduled` until then.
End Date (Optional)	Blank	The last day. Blank means the campaign runs until its list is exhausted or you stop it.
Call Time - From	`09:00`	Start of the daily window.
Call Time - To	`17:00`	End of the daily window. A call that is in progress at this time is not cut.
Days of Week		Tick each day calls are allowed.
Timezone	Your browser’s	The zone the window is expressed in, with its offset, as in `Europe/Paris (GMT+2)`.
Enable retry attempts	Off	Reveals Retry Configuration.

The Retry Configuration section with two attempts, each with a delay and units — The schedule step with two retry attempts.

Choosing the timezone

The window is one clock for the whole campaign. Set Timezone to where the contacts are, not where you are: a 09:00 to 17:00 window in America/Chicago rings a list of Texas numbers during their working day. The campaign’s page shows the window in the campaign zone and, when your zone differs, underneath converted to your local time, so the two can be checked against each other.

A list that spans several zones is better split into one campaign per zone, on the same agent and number, with a tag per zone.

Retries

With Enable retry attempts on, Retry Configuration lists attempts. Each has a Delay (60 by default) and Units (Seconds, Minutes, Hours or Days; Minutes by default). Add Another Retry appends the next attempt. A contact whose call ended without a conversation is called again after the delay, inside the window; after the last attempt it is left alone.

Retries apply to calls that did not reach a person: busy, no answer, unreachable, and, when answering machine detection is on, voicemail. A call the agent held is not retried.

A sensible first policy is 2 attempts: 2 Hours, then 1 Days. Calling back in minutes reaches the same voicemail.

Verify

The campaign card under Launch AI Voice shows the window and zone, as in 9:00–17:00 Europe/Paris, or Anytime when no hours were set.
On the campaign’s page, Campaign configuration repeats Time Zone, Call Hours (with your local equivalent), Days of Week, Start Date and, when set, End Date.
Outside the window the campaign holds and Total Calls stays flat; inside it the count moves.

Troubleshooting

Nothing dials on the start date. Check that the day is ticked under Days of Week and that the current time falls inside Call Time in the campaign’s Timezone, not yours.
A contact was called twice in a minute. The first retry’s Delay is in Seconds. Change the Units.
Contacts who answered are being called again. They hung up before the agent spoke, so the call counted as unanswered. Check the agent’s first message and who talks first.
