Campaigns
Running a voice agent against a list of contacts at scale
A campaign is how you run a workflow against many contacts automatically. Instead of triggering calls one by one via the API, you upload a list of phone numbers and Talkr dials them for you — respecting scheduling windows, concurrency limits, and retry rules.

phone_numbercolumn; any extra columns becomeinitial_contextfor each call - Create the campaign — link it to a workflow, set concurrency, time slots, and retry behaviour
- Start it — Talkr begins dialing contacts up to your concurrency limit
- Monitor progress — track processed, completed, failed, and pending counts in real time
- Pause and resume — stop and restart at any point without losing progress
The contacts CSV
The CSV drives the campaign. Each row is one contact.
phone_number,customer_name,account_id,plan
+14155550100,Jane Smith,acc_001,premium
+14155550101,Bob Jones,acc_002,basicColumns beyond phone_number are automatically passed as initial_context to each call, making them available as template variables in your agent's prompt — so each call can feel personalised at scale.
Scheduling and concurrency
Concurrency controls how many calls run simultaneously. It's capped by your telephony plan. Set it conservatively to start.
Time slots restrict when Talkr is allowed to dial — useful for respecting business hours or regulations:
{
"timezone": "America/New_York",
"time_slots": [
{ "day": "monday", "start": "09:00", "end": "17:00" },
{ "day": "tuesday", "start": "09:00", "end": "17:00" }
]
}If no time slots are set, Talkr dials continuously once the campaign is started.
Retry behaviour
Talkr can automatically retry contacts who didn't answer, were busy, or went to voicemail:
{
"retry_config": {
"enabled": true,
"max_retries": 2,
"retry_delay_seconds": 120,
"retry_on_busy": true,
"retry_on_no_answer": true,
"retry_on_voicemail": true
}
}Circuit breaker
The circuit breaker automatically pauses a campaign when the call failure rate gets too high — protecting against wasted spend and telephony reputation issues caused by a misconfigured agent or a bad contact list.
When enabled, Talkr monitors the failure rate within a rolling time window. If it exceeds the threshold, the campaign is paused automatically and must be manually resumed after the issue is investigated.
| Setting | Default | Description |
|---|---|---|
| Failure Threshold (%) | 50 | Pause when the failure rate within the window exceeds this percentage |
| Window (seconds) | 120 | Rolling time window over which the failure rate is calculated |
| Min Calls in Window | 5 | Minimum number of calls required before the circuit breaker can trip — prevents false positives on small samples |
A campaign paused by the circuit breaker behaves the same as a manually paused campaign — in-flight calls complete normally, and it can be resumed once the underlying issue is resolved.
Campaign lifecycle
| Status | Meaning |
|---|---|
created | Set up but not started |
syncing | Processing the uploaded contacts CSV |
running | Actively dialing |
paused | Stopped; resumes from where it left off |
completed | All contacts processed |
failed | Encountered a fatal error |
You can pause and resume a campaign at any time. In-flight calls complete normally before a pause takes effect.
Results
Each contact's call creates a run record with the full transcript, recording, and gathered context — same as a manually triggered call. Use the Get Campaign Runs endpoint to retrieve them all.
