Hello,
kamailio has an embedded msrp relay functionality. You have to load and
configure msrp module -- it is new in upcoming release (3.3.0, planned
to be out about mid of June):
http://kamailio.org/docs/modules/devel/modules/msrp.html
Have you tried with it as well? I developed the current version, but had
no good clients I could test with at that time, so I used mainly network
sending tools to simulate msrp traffic.
Cheers,
Daniel

Hi,
We are developing a Java based SIP gateway implementation and are
performing some integration tests on a kamailio/msrprelay server
(plugin from www.msrprelay.org).
The SIP signaling part works so far, but when sending a MSRP message,
the client receives a 501 "Unknown method" error. However, it seems
the request does not reach the MSRP module on the server as there is
no corresponding trace log on the server side.
On Protocol level, everything looks fine so far, the sequence executed
is as follows:
-->SIP REGISTER
<-- SIP/2.0 401 Unauthorized
-->SIP REGISTER
<--SIP/2.0 200 OK
-->INVITE
<--SIP/2.0 407 Proxy Authentication Required
-->ACK
-->INVITE
<--SIP/2.0 180 Ringing
<--SIP/2.0 180 Ringing
<--SIP/2.0 200 OK
-->ACK
The INVITE is processed with the following SDP packet in the request:
v=0
o=- 1337788359935 1337788359935 IN IP4 localhost
s=MSRP Session
c=IN IP4 localhost
t=0 0
m=message 2855 TCP/MSRP *
a=path:msrp://localhost:2855/U3FuvW00m62UY0020H71;tcp
a=accept-types:message/cpim text/* application/im-iscomposing+xml
a=accept-wrapped-types:*
a=setup:active
And response:
v=0
o=- 3546777215 3546777216 IN IP4 46.105.78.68
s=sipsimple 0.20.0
c=IN IP4 46.105.78.68
t=0 0
m=message 57233 TCP/MSRP *
a=path:msrp://msrphost:2855/5AUNTOt7XlFsK7VuT4SzETEzMzc3ODg0MTUuMDcyOjQ2LjEwNS43OC42OA==;tcp
msrp://msrphost:57233/6bf6dd73b9e4587b65b6;tcp
a=accept-types:message/cpim text/* application/im-iscomposing+xml
a=accept-wrapped-types:*
a=setup:passive
But when sending the MSRP message, 501 is returned:
MSRP f0CHA1TD SEND
To-Path: msrp://msrphost:57233/6bf6dd73b9e4587b65b6;tcp
From-Path: msrp://localhost:52673/b10XadK9;tcp
Message-ID: 13377883623135c260a3568cc
Byte-Range: 1-*/14
Hello Francois
-------f0CHA1TD$
MSRP f0CHA1TD 501 Unknown method: SEND
To-Path: msrp://localhost:52673/b10XadK9;tcp
From-Path: msrp://msrphost:57233/6bf6dd73b9e4587b65b6;tcp
-------f0CHA1TD$
When testing with two sip-simple client endpoints, MSRP messaging
works fine, but on protocol traces we cannot identify any differences
between sip-simple communication flows and the ones we are implementing.
Does anyone have a hint on what is wrong in this message flow? Any
advice is appreciated.
Thanks,
Alex
