Discussion on the last point from October 18th:

  1. Current requirement for the use of Direct addresses:
    • The From address in the initial request SHALL be used by the recipient to send back an accept or decline
  2. Add the following
    • When the recipient sends an Accept response back to the initiator, the From address MAY be different from the To address on the initial request.
    • If the initiator receives an Accept response with a From address which is different from the To address used on the initial request, it SHALL process the response properly based on the patient and referral identifiers in the metadata. Any further transactions from the initiator to the recipient can use either the new From address or the original To address as the destination.
    • If an Accept response is sent back to the initiator with a From address that is different from the To address on the initial request, the recipient SHALL be able to process any further transactions from the initiator on either of these two addresses.
