This package contains a Python SDK for Azure Communication Call Automation. Call Automation provides developers the ability to build server-based, intelligent call workflows, and call recording for voice and PSTN channels.

DisclaimerAzure SDK Python packages support for Python 2.7 has ended 01 January 2022. For more information and questions, please refer to https://github.com/Azure/azure-sdk-for-python/issues/20691
Getting started PrerequisitesInstall the Azure Communication Service Call Automation SDK.
pip install azure-communication-callautomation
CallAutomationClient is the primary interface for developers using this client library. It can be used to initiate calls by createCall or answerCall. It can also be used to do recording actions such as startRecording CallConnectionClient CallConnectionClient represents a ongoing call. Once the call is established with createCall or answerCall, further actions can be performed for the call, such as transfer or play_media. Callback Events Callback events are events sent back during duration of the call. It gives information and state of the call, such as CallConnected. CallbackUrl must be provided during createCall and answerCall, and callback events will be sent to this url. Incoming Call Event When incoming call happens (that can be answered with answerCall), incoming call eventgrid event will be sent. This is different from Callback events above, and should be setup on Azure portal. See Incoming Call for detail. 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)
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
# 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)
