Unity just fine.   If you have any issues, place router-based software
MTPs on your Cube gateway.  Many times you will encounter issues with
transfers, conference, etc with SIP users over a SIP trunk.  The reason is
that the re-invite is sent to the telco and many times they do not handle
those.  By tying to an MTP, you keep all call manipulation in-house and at
