Hi Medo, even if the popular IMS books (e.g. Camarillo's: "The 3G IP Multimedia Subsystem") states something different and i made the mistake at my last presentation at KamailioWorld stating something different, the current MSRP-Implementation of Kamailio is not compliant to GSMA's RCS-Specs. With the known Implementations of RCS-Clients, you cannot configure a MSRP-Relay. According to the Specs, you do not need a MSRP-Relay, but more a MSRP-Back-2-Back-Useragent (to implement "Store-and-Forward" and Offline Message storage, instead of making an End-2-End Session), which is not implemented in any Open-Source solution i know.
