We use kamailio 3.2 and imsdroid to make videocalls, send messages etc. What we have to this moment is kamailio 3.2, rtpproxy, asterisk and modified imsdroid (for Android phones). Asterisk is used for billing and some other services.<div>
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. For other messages may be exactly something like MSRP is must. Doesn't matter what and how we do, best what we receive now is "attempt" to send message. Receiver receive notification and nothing more - neither user, nor content.</div>
<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><br><div class="gmail_quote">On Tue, Jan 17, 2012 at 6:00 PM, Carsten Bock <span dir="ltr"><<a href="mailto:carsten@ng-voice.com">carsten@ng-voice.com</a>></span> wrote:<br>
