Passthrough media change method optimizes or consumes mid-call, media-related signaling within the call. Mid-call signaling changes will be passed through only when bidirectional media like T.38 (aka fax) or video is added. The command midcall-signaling passthru media-change needs to be configured to enable passthrough media change. https://www.cisco.com/c/en/us/td/docs/ios-xml/ios/voice/cube/configuration/cube-book/voi-cube-midcall-reinvite.html#GUID-F5641A05-14F7-4396-B04B-5F1D4F527457
