Shortly after I sent this I figured out that I could use AMP found at Advanced->Configuration->Phone Setup to setup the multiple phone lines and adapters. This, however, did not setup the phone devices in the Wizard and also seemed to removed the Phone Lines entries in the Wizard.
Since it's really late I can't do much more testing on the phone lines. I was , however, able to verify that outbound calling is working, but inbound is not. For some reason Asterisk is detecting the wrong phone number. This did not happen with the standalone asterisk using the exact same register string... I'll work on it some more tomorrow...
