Looks like I just answered my own question. You can't have a device
that matches the user extension. With it configured like this the
invite from won't match a SIP peer and it will default to IP lookup.

Using INVITE request as basis request - 413feda8-186c-4fe1-a82d-eb074be527e1
Found peer 'exchange-vm' for '2001' from 10.10.1.31:63436
Peer has insecure flags port,invite
Looking for 2001 in from-internal (domain voip.mydomain.net)
