Hey there! If you want to make bulk calls in LiveKit, you can totally use the SIP participant creation API. Let me walk you through it step-by-step: 1. Prepare Your Data: Start by creating a CSV file with phone numbers and any extra info you want to include. For example:

phone_number,question
+1234567890,Hello! How are you today?
+9876543210,This is a test call.

2. Use the Python Example: You can use a script to read your CSV and make the calls. The script will create a room, dispatch, and a SIP participant for each call. Here’s a quick example:

async def make_survey_call(phone_number, question, row_index):
    room_name = f"room_{row_index}"
    metadata = json.dumps({"phone_number": phone_number, "question": question})
    sip_participant = await lkapi.sip.create_sip_participant(
        api.CreateSIPParticipantRequest(
            room_name=room_name,
            sip_trunk_id=outbound_trunk_id,
            sip_call_to=phone_number,
            participant_identity="phone_user"))

3. Process the CSV: Just read through your CSV and kick off calls for each row. 4. Set Environment Variables: Make sure you’ve got these set up: ◦ LIVEKIT_API_KEY ◦ LIVEKIT_API_SECRET ◦ LIVEKIT_URL ◦ SIP_OUTBOUND_TRUNK_ID 1. Run the Script: Run your script with all the right dependencies, and don’t forget to handle things like rate limits, errors, and retries so everything goes smoothly.

Hey there! Here’s a handy Python script to help you make bulk calls using LiveKit with a CSV file named

sample.csv

. Just make sure you have the necessary dependencies and environment variables set up as explained below: 1. Install Dependencies: Simply run

pip install livekit python-dotenv

to get started. 2. Create a .env File: Pop in your LiveKit credentials like this:

LIVEKIT_URL=<your_livekit_server_url>
LIVEKIT_API_KEY=<your_api_key>
LIVEKIT_API_SECRET=<your_api_secret>
SIP_OUTBOUND_TRUNK_ID=<your_sip_outbound_trunk_id>

3. CSV File Format: Make sure your

sample.csv

looks like this:

Phone Number,Question,Answer,Status
+1231231231,Do you prefer chocolate or vanilla ice cream?,,

Here’s the script for you:

import asyncio
import csv
import json
import os
from dotenv import load_dotenv
from livekit import api

load_dotenv()

async def make_call(phone_number, question, row_index):
    room_name = f"bulk-call-{row_index}"
    metadata = json.dumps({"phone_number": phone_number, "question": question})
    lkapi = api.LiveKitAPI()
    await lkapi.sip.create_sip_participant(api.CreateSIPParticipantRequest(
        room_name=room_name,
        sip_trunk_id=os.getenv("SIP_OUTBOUND_TRUNK_ID"),
        sip_call_to=phone_number,
        participant_identity="phone_user"))
    await lkapi.aclose()

async def process_calls():
    with open("sample.csv", "r") as f:
        reader = csv.DictReader(f)
        for i, row in enumerate(reader):
            if not row["Answer"]:
                await make_call(row["Phone Number"], row["Question"], i+1)

asyncio.run(process_calls())

Just save this as

bulk_caller.py

and run it with

python3 bulk_caller.py

. If you hit any bumps or have questions, feel free to ask—I’m here to help!
