Hi Medo, 1) you should make a packet trace, to figure out, why the Kamailio MSRP-Relay is not working. It is likely a problem with your clients (WebRTC or RCS) and not with Kamailio, The Kamailio MSRP-Relay works with different clients, successfully tested. 2) Unless you replaced the MSRP-Stack of RCS-Client (or at least do major changes), you will not have luck with your setup. RCS-MSRP (as per GSMA) is not really compatible with Plain-MSRP (as per RFC), you really need deep protocol knowledge to fix it; it cannot be easily fixed.
