We have a BT Digital Voice phone with built-in Alexa. We also have two mobile phones on BT contracts but cannot link them to our Amazon Echo. This could be done with an EE contract. As BT own EE it would be great if we could link our BT phones to our Amazon Echo (via EE?) to allow us to make hands-free calls.
have you installed alexa app on your phones? that way you will link alexa with hub and phone and then use alexa to make calls using your mobile phone contact list
