Once the app is installed, users may access the calling features from any HubSpot Object with an associated phone number.
Selecting the Call button on the record will display the calling options. Make sure that OneCloud is selected as the calling provider.
To place the outbound call, select the phone number in the dropdown you are attempting to call.
If this is your first time launching the application, you will need to enter your OneCloud credentials. Once you are authenticated, the call will be placed.

Your authentication session will be stored in your browser's cache allowing subsequent calls to be placed immediately.
