This should be possible.  The trick is, the domain sip:sbc.network.net 
should not resolve as the local address of OpenSBC.   If 
sip:sbc.network.net is a local address, then OpenSBC would try to be 
authoritative over the registrations.    The correct format would be:

[sip:sipx.network.net*] sip:sipx.network.net:5060

I am suggesting B2BUpperReg Mode.  This would limit the work of OpenSBC 
to b2bua and upper reg.  Full mode includes the proxy functionality.

No.  B2BUpperReg routes are just static routes for OpenSBC to follow in 
case the remote domain is not resolvable via DNS.  In  B2BUpperReg mode, 
you don't even have to put anything in the routes as long as the To-URI 
resolves to a remote domain.

Solegy (Sponsor Company of OpenSBC) has a similar setup.  In fact 
B2BUpperReg mode came into life when we started to evaluate sipXecs.
