Key concepts

Name
Description

CallAutomationClient
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.communication.callautomation import (CallAutomationClient)

# Your unique Azure Communication service endpoint
endpoint_url = '<ENDPOINT>'
client = CallAutomationClient.from_connection_string(endpoint_url)

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_uri
)

# 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)
