CSC issues with Cloverleaf interface engine.

Our company recently purchased Relay Health which utilizes Cloverleaf Secure Courier instead of a VPN connection to our Cloverleaf interface engine.  We have a major issue in that when we send data and it pass through the CSC to the Relay health server, It sends back an acknowledgement message to the CSC  and that is all that happens. When the data is routed to the CSC it does not send an ACK Message back to the cloverleaf engine.  This is creating major issues.  I turned off the option on the engine to await replies and finally took the saveob_message proc off so that data would flow and not create a huge error log.  This allow data to flow but then we have no idea if this successfully posted in the CSC. When I took the proc to save ob msg off the vendor indicated that they no longer got the messages.  I think there was something else going on at the time but in the interim the proc has been put back on this thread creating huge error logs again. 😥

Does the CSC have the capability of sending an acknowledgement message.  The vendor seems unable to help us this our predicament.
