Yes. Using Alexa only, you can directly call Bose smart products, Amazon Echo products and anyone in your contacts list. Simply say, “Alexa, call Mum”, to initiate a call. Or say “Alexa, answer”, to accept an incoming call. You do not need your phone to make or take a call, and it’s free of charge. However, when calling products, both parties are required to have this feature set up and must be on Wi-Fi in order to use it.Currently, Amazon Alexa works with QC35 headphones II, Headphones 700, Home Speaker 300, Smart Speaker 500, Portable Smart Speaker, Smart Soundbar 300, Soundbar 500 and Smart Soundbar 700.
