When BypassMode is defined, Direct Routing adds X-MS-UserLocation (internal or external), X-MS-MediaPath (the ordered SBCs for the media path, target SBC last) and X-MS-UserSite (the administrator-defined site) to INVITEs and re-INVITEs, and puts the target SBC FQDN in the Request-URI even when that SBC is not directly connected.
