title: Where does Mirth Listen for HL7 acknowledgement messages?
body: <p>I have a mirth channel that listens to a source and then deploys the inbound communications to several channels.   One of these channels sends the HL7 to an application I am developing, and I do not know where to send my ack message. Should I send it to the inbound port of the original message, or does MIRTH have a specific process for sending acknowledgements?  </p>
