Settings > Phone > Mobile forwarding. Enable. Pick which numbers forward to your mobile (default: all). Set a delay (default: 12 seconds, then mobile).
How it sounds
When a customer calls, we route to your mobile via the carrier. Your phone shows the Message caller ID with the customer name (if known).
Status sync
Picking up the call on mobile sets your dashboard status to On call automatically. Other agents see the call is being handled.
