In Microsoft's Always-bypass examples, an outbound call from an internal user at the downstream site carries X-MS-UserLocation: internal and X-MS-MediaPath naming only the downstream SBC, while an external user's call carries X-MS-UserLocation: external and X-MS-MediaPath listing the proxy SBC then the downstream SBC.
