I have looked all over and found many references to how this might be done, but most of the references were 3 to 4 years old.

How do you configure the Quadro M8L (5.2.40) and the Phones so the Phones work on the WAN?

I have changed the Line Settings to Configure IP Phones on WAN.
Does the Auto-provisioning not work when the phones are connected to the WAN?
Do you still have to manually configure the phones like the older post indicate?
Do you need to connect the WAN and LAN port to the switch like the older post indicate to get the auto-provisioning to work?

Thanks in advance for your help, it is appreciated.
