HL7 to Quadramed

Hi,

IHAC who is trying to connect Ensemble to Quadramed for HL7 messaging, however, it seems that in order to do this, the following is required:

"we open a passive connection to Quadramed and then listen for a connection request from Quadramed, once this is established we then send messages"

Has anyone done this before?  Is this possible with the standard HL7 components?

Thanks,

Steve.
