How will I know when someone is calling my QuickPBX line? How do I change it?

The caller ID on your phone will show your QuickPBX number as the calling number, so you'll know it's someone who dialed that number. You can easily set your QuickPBX number with an identifying name in your Caller ID so that it pops up when someone calls.

You can change the setting of any extension to show the Caller ID of the caller instead of your QuickPBX number in Call Forwarding settings.
