Kamailio does not send any command to RTPProxy unless it handles some
SIP messages, the U and L commands are typically for INVITEs and 200ok.
Have you looked at sip traffic? You can run ngrep on kamailio server:
ngrep -d any -qt -W byline port 5060

Hi Daniel,
My clients don't do anything when IP change occurs.From what I
inspect, it is because of rtpproxy does not accept the 2nd IP change.
The the rtpproxy protocol document
http://www.rtpproxy.org/wiki/RTPproxy/Protocol, the Update and
Lookup command have [arg] parameters.
U[args] callid addr port from_tag [to_tag [notify_socket
[notify_args]]]
L[args] callid addr port from_tag to_tag
I see Kamailio often send Uc and Lc to rtpproxy. I still can't
find out what these arg mean, but maybe it's the point

I have SIP proxy (Kamailio) works in conjunction with
rtpproxy <http://www.rtpproxy.org/> to support client
communication. When SIP proxy sends command to rtpproxy to
create new session, rtpproxy will create 2 ports (let's
called them port1 and port2). rtpproxy has 1 listen interface
Supposed A and B are 2 clients that use rtpproxy to relay RTP
stream, and works fine.
A <---> port1 [*rtpproxy*] port2 <---> B
Now that A loses his current network, and enter network2
(imagine a network handover) to become A2. In this case, I
see rtpproxy still works fine by relaying stream between A2 and B
A2 <---> port1 [*rtpproxy*] port2 <---> B
But when A2 lose his network2 and enters network3 to become
A3, rtpproxy stills relay stream between A2 and B. It seems
that A can change his network only once.
A2 <---> port1 [*rtpproxy*] port2 <---> B
A3
Why did the first handover succeed? How can I change rtpproxy
behavior to support many handovers ?
what I expect that happened between A and A2 is that the
client application sent a re-INVITE with its new IP address.
But then it didn't happen when going to A3. Rtpproxy itself
can do nothing here. You should look at sip traffic to see
what happens.
Cheers,
Daniel
