You can point a voxitas DID at a sipxecs 4.4 server using unified messaging. I do that with voxitas now.
I can also use a patton fxs port on a smartnode gateway to receive via paper (i register the fxs with sipx) and send out via voxitas. the patton smartnode is t.38 capable and is configured for it. I think of you were to do either of these things, it would work. Voxitas is not unusual that the DID/account has to be provisioned over a different route (where they can better guarantee t.38) becuase a lot of ITSP's don;t support t.38. Trying to fax over g711 is a joke. If you don't request it, it doesn't happen automatically.
