Shoretel PBX & SIP - VPN to MPLS

We are Migrating from a traditional internet VPN to MPLS network.  We have a shoretel PBX on premise and an ingate Siperator handling SIP calls.  We have QoS in place on switches.
Is it possible to house the SIperator at one of the sites rather than hosting in the DC?  If so how to route the traffic from Web to MPLS to site?

I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

So the Siperator sits in front of a firewall which sits in front of the PBX at the DC? If it's like a session border controller, probably "no". And I am not sure I follow why you'd want to de-couple the siperator from your PBX.

What are you trying to accomplish by changing the architecture?

Have fun!
