Source note · Setting up an Oracle SBC for Teams Direct Routing

In the current carrier model, the carrier creates one carrier trunk in its own tenant with New-CSOnlinePSTNGateway; customer tenants add the derived trunk FQDN (for example customer.sbc1.base) to voice routes without registering it, derived trunks inherit all carrier-trunk settings including media bypass and port, OPTIONS go only to the carrier trunk FQDN, and the carrier must publish DNS resolving each derived FQDN to the SBC.
