This conversation has been merged. Please reference the main conversation: Control ring order of Desktop App and Mobile App.
The system currently supports simultaneous soft android and soft PC ringing when an extension is dial directly, but not upon sequential transfer. There is no workaround in call handling or groups. Seems like a basis feature is missing here. This is important, because small business owners (your niche) are sometimes sitting at their desks and sometimes walking around with their mobiles.
