A method for using voice interaction to access functionality of a digital assistant, the method comprising:

• at a primary electronic device having a processor, memory, and a speaker:
• receiving, from a companion electronic device, audio data of a communication session, wherein the audio data represents an utterance received by the primary electronic device, wherein the audio data is transmitted from a far-end party of an active call via the communication session connection, wherein the far-end party includes a third an external electronic device, and wherein the primary electronic device is in communication with the companion electronic device;
• invoke, based on the received audio data, a digital assistant on the primary electronic device;
• determining, based on the audio data, a user intent corresponding to the utterance;
• determining one or more tasks to satisfy the user intent;
• determining, based on results of performing the one or more tasks, a digital assistant response;
• and transmitting the digital assistant response to the companion electronic device, wherein the primary electronic device transmits the digital assistant response to the external electronic device of the far-end party via the communication session connection.
