Operations

1. Initiate an outbound call

Aircall:

POST https://api.aircall.io/v1/calls
Authorization: Bearer {TOKEN}
Content-Type: application/json

{
  "number_id": {AIRCALL_NUMBER_ID},
  "to": "+14155551234",
  "metadata": {
    "prospect_id": "abc123",
    "campaign": "outbound-email-li-calls",
    "signal_type": "funding_round"
  }
}

JustCall:

POST https://api.justcall.io/v1/calls/outbound
Authorization: Bearer {TOKEN}
Content-Type: application/json

{
  "from": "+14155559876",
  "to": "+14155551234",
  "contact_name": "Jane Smith",
  "custom_fields": {
    "campaign": "outbound-email-li-calls",
    "prospect_tier": "1"
  }
}

2. Log call outcome

After the call ends, update the disposition:

Aircall:

PUT https://api.aircall.io/v1/calls/{CALL_ID}
{
  "tags": ["meeting_set"],
  "comment": "Discussed pipeline challenges. Booked 30-min demo for Thursday."
}

JustCall:

PUT https://api.justcall.io/v1/calls/{CALL_ID}/disposition
{
  "disposition": "meeting_booked",
  "notes": "Interested in demo. Confirmed Thursday 2pm."
}

3. Drop a pre-recorded voicemail

When a call goes to voicemail, drop a pre-recorded message instead of speaking live:

PhoneBurner:

POST https://api.phoneburner.com/rest/1/voicemail/drop
{
  "call_id": "{CALL_ID}",
  "voicemail_id": "{PRE_RECORDED_VM_ID}"
}

Pre-record 2-3 voicemail variants. Keep each under 20 seconds. Reference the email you sent: "Hi [name], this is [founder] from [company]. I sent you a note earlier this week about [topic]. Would love 15 minutes to discuss. My number is [number]."

4. Retrieve call recordings

GET https://api.aircall.io/v1/calls/{CALL_ID}

Response includes recording URL. Download or pass to Fireflies/Gong for transcription and analysis.

5. Get call analytics

Aircall:

GET https://api.aircall.io/v1/calls?direction=outbound&from={START_DATE}&to={END_DATE}

Returns all outbound calls with duration, outcome tags, and recording URLs. Aggregate for connect rate and meeting conversion.

Error Handling

• Number not reachable: Log as call_no_answer with attempt count. Retry max 3 times across 3 different days/times.
• Wrong number: Remove from call list and flag in CRM. Do not retry.
• Rate limits: Most dialers allow 1 concurrent call per user/line. Queue calls in n8n and process sequentially.
• Local presence: Use local area code matching when available (Kixie, Aircall) to increase connect rates by 2-3x.

CRM Sync

After every call, push the outcome to your CRM:

POST https://api.attio.com/v2/objects/people/records/{PERSON_ID}/notes
{
  "data": {
    "title": "Outbound call - {DISPOSITION}",
    "content": "{CALL_NOTES}",
    "created_at": "{TIMESTAMP}"
  }
}

Tag the contact with last_call_date, call_disposition, and call_attempt_count.
