Explanation

Microsoft SIP Gateway works by redirecting SIP handsets to a Microsoft-hosted provisioning server, which re-provisions the device with firmware and configuration that enables Teams sign-in. If the Teams sign-in option does not appear, it means the handset has not yet been pointed to the Microsoft SIP Gateway provisioning server URL. Setting the correct provisioning server URL in the handset's configuration causes it to contact Microsoft's server, download the required Teams-compatible configuration, and present the Teams sign-in option. IPv6 (Option A), MAC address registration (Option B), password complexity (Option C), and PC port connections (Option D) are not required for the sign-in option to appear.
