Shouldn't this be a function of the remote device as well.   After all, if
it has the mappings to the two different IP addresses for the WAN ports,
should you be able to register either way?  In a failure of it's primary
registration, you need it to register with the secondary WAN port.  A manual
way around this is with a client that allows for multiple accounts, and you
have one account registered to one WAN port, and one to a secondary WAN
port.

Well, technically if you are in a fail-over type situation and you have a
login type sip trunk provider your login should start using the other route.

 

Or, if you use a login type SIP trunk and a static IP type SIP trunk could
you route the two difference scenarios out different internet connections
based on destination address with the firewall?  A login type SIP trunk does
not require you to map traffic.  Actually, that might not work if one of
those needs a 1:1 nat.  Ok, 2 login type SIP trunks would probably work.

 

In fact, with a static IP type SIP trunk you need to do 1:1 nat to an
outside IP in the firewall...  I don't see how this type of connection would
work with only a single IP on the sipXecs box...  that brings up the whole
multiple network card type problem.

Right, but my use case was a simple system with dual wan. Seems like a
lot to go through (second sipx install or sbc install) to use a second
wan port fully, and it only affects remote users.
