probably this is via MESSAGE requests, which is so called page-mode
instant messaging. Kamailio is enough to route them, no need for rtp
proxy or msrp relay. You can do a ngrep on the kamailio server and see
what sip requests are passing through.

Also here, watching the sip traffic on the kamailio server with ngrep
should give leads about how it is done, if it is SIP at all. You can use
a command like:
ngrep -d any -qt -W byline port 5060

Any linux/mac os x variant -- it is where I can test easily.
