rtpproxy, asterisk and modified imsdroid (for Android phones).
Asterisk is used for billing and some other services.

Imsdroid can send 2 kind of messages. One of them is called SMS
and they can go directly using kamailio and rtpproxy. I can get
logs and provide here as much as possible about this type of
messages. </div>

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.<br>

<div>For other messages may be exactly something like MSRP is

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:<br>
<br>
ngrep -d any -qt -W byline port 5060<br>

<div>We have lot of experience with Asterisk, but only few months
with Kamailio and almost no experience with messages. May be we
do something else wrong, but what I can do is using wireshark to
post here some results.</div>
<div>By the way - there are variants of imsdroid (with other
names) for iPhone, and Windows - but with windows version we got
bad results. Android version works very well.<br>

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