Here is a little bit harder question:

I want my local outbound calls to use an FXO interface
as described in this thread however...

If there is no available FXO interface then I'd like the
called go through my SIP service provider who will gateway
the call back to PSTN for me (for a small per minute fee and
slight loss of quality)  I want to use SIP as a backup.

In some long distance cases SIP will be primary with the
FXO as a backup (incase the Intrnet service is down or whatever)

So the generized question is how to do across channel type
fail overs?
