When we direct a call to another JustCall user or JC number, we don't mention whether it is a transferred call or a direct inbound call from the customer on any platform, be it a web dialer, desktop app, extension, or mobile app.
Below call was a direct transfer call but no details were specified on the dialer and it goes for all the platforms.
It does show on the desktop app, but would love this feature for phones. Not many people use the desktop app and are always confused whether the call is being transferred or direct.
