Use Google Assistant to Make Calls

Ask Google to make a call using 3CX, be it by name e.g. “OK Google, call James using 3CX” or by number e.g. “OK Google, call 101 using 3CX”. When calling by name, the Google Assistant will try to find a person in your device’s contacts, to pass on to the 3CX App.

  • If only one contact is found to have one number, the call is initiated immediately.
  • If the contact has multiple numbers, the 3CX App will open the contact card for you to choose the number to call.
  • In the case of several people with the same name, the 3CX App will filter all contacts by name for you to choose the correct contact.

To set up:

  • Enable Google Assistant on your device.
  • Ensure both the device and Google assistant region are set to “English (US)”.
  • Install the 3CX App with an active account.
