Hello, Just some info regarding feature tags usages in 3gpp IMS: TS 23.279 and 24.279 specified csi(Combining Circuit Switched (CS) and IP Multimedia Subsystem (IMS) services;) and defined feature tags for this scenario.
Moreover, I guess, the SIP usage in IMS should be a topic of 3gpp instead of the ietf list.
