Reverse Invoke Vs Outbound

Hi,

I have done the setup for the reverse invoke. One IS is inside firewall and one is in DMZ. The DMZ box is connected to Trading partner via secure pipeline. And the port 80 is open for ourbound and 8080 for inbound.

The questions is, How do I make http outbound calls from internal IS to Trading partner?. Will reverse invoke work for only inbound calls?.

Thanks,
Jey.
