John:
Good question, I have the answer for you.
You can tell the box to prefer one connection over the other for certain
routes (based on source or destination IP address) during normal operation
(both connections up). If the preferred connection fails, then the traffic
falls over to the other connection.

I 100% agree with the rational for what you are doing, however I wouldn't
do this on the Asterisk box.
I would look into a hardware appliance for this.
Something like a HotBrick LB-2 would work great for this and they are
fairly cheap as well.

This might not perform as you expect. It's probably used to load balance
things like HTTP sessions where the from IP address is less of an issue.
How would one control which WAN would be used to register SIP? Then when a
WAN connection fails Asterisk would still need to re-register. Could you
register via both?
When I've done this in the past, I've established a VPN over the Internet
(I controlled both ends) and when the IP changed the VPN would
re-establish and all the existing connections would lurch forward and
continue one. Still in your case calls would go dead until the LAN
re-established.
