Explanation

SIP Gateway enables compatible third-party SIP devices (such as Cisco handsets) to register with Microsoft Teams. The first step is to modify DHCP option 160 (or 66) to point the provisioning server URL to Microsoft's SIP Gateway provisioning service. When the Cisco handsets boot up, they query DHCP for the provisioning server address, download their configuration from Microsoft's provisioning endpoint, and then register with Teams. Without updating the DHCP provisioning URL, the phones will continue pointing to their old PBX provisioning server and cannot onboard to Teams. LLDP (B) is for network discovery, not provisioning. The web server (C) and PC port (D) steps may come later in the process but are not the first required action.
