Installing

Install the Azure Communication Service Call Automation SDK.

pip install azure-communication-callautomation

Key concepts

Examples

Initialize CallAutomationClient

from azure.identity import DefaultAzureCredential
from azure.communication.callautomation import (CallAutomationClient)

# Your unique Azure Communication service endpoint
endpoint_url = '<ENDPOINT>'
credential = DefaultAzureCredential()
client = CallAutomationClient(endpoint_url, credential)

Create Call

from azure.communication.callautomation import (
    CallAutomationClient,
    CommunicationUserIdentifier
)

# target endpoint for ACS User
user = CommunicationUserIdentifier("8:acs:...")

# callback url to receive callback events
callback_url = "https://<MY-EVENT-HANDLER-URL>/events"

# send out the invitation, creating call
result = client.create_call(
    target_participant=user,
    callback_url=callback_url
)

# this id can be used to do further actions in the call
call_connection_id = result.call_connection_id

Play Media

# using call connection id, get call connection
call_connection = client.get_call_connection(call_connection_id)

# from callconnection of result above, play media to all participants
my_file = FileSource(url="https://<FILE-SOURCE>/<SOME-FILE>.wav")
call_connection.play_to_all(my_file)
