Yes, that would be a much better way of expressing the issue.

Without topology hiding, the Mitel will ignore Record-Route headers. If
using topology hiding, they will send an in-dialog invite to the sdp c=
address...

Can hack around it by using both topology hiding and rtpproxy but would
rather see if I could get the Mitel to behave in a more respectful manner.

I've also thrown in either FreeSWITCH or Asterisk as a media server for
those end-points to just "handle" it; which may end up being a decent
solution for the trouble-making end-points.
