This response is based on the information provided.  We suggest you discuss with your contracting team, program manager and/or legal department as appropriate. 

We are assuming you are referring to Post Award Orientation, the details of which you will find in FAR subpart 42.5.  Post Award Orientations are commonly referred to as kick-offs.  "Multifunctional team meeting" is, we believe, a generic term - not specific to any particularly type of meeting.  It should seem to be the way the Management Information System/documentation database your organization is using refers to meetings.  Understanding the purpose of a meeting and its intended outcomes is the focus.
