MSRP is another type of media, like RTP media which is used for audio/video.
If SylkServer is sitting on a public IP, MSRP media should just work as the server is always reachable by an MSRP client.
Short hint, enable logging and see what happens, each protocol can be debugged to a file logged by SylkServer.
