You have to run rtpproxy (or rtpengine) in bridging mode and
instruct it to do bridging from kamailio cfg using 'e' and 'i' flags
(iirc, there is an alg.cfg inside nathelper examples folder that
gives some hints, good for starting -- also searching on web for
rtpproxy in brdige mode may reveal some useful info).<br>

<div>I do have a similar setup and encounter the audio
problem<br>
<br>
</div>
My Kamailio sits behind a router listening to the public ip
sip port 5060 and use internal lan ip to communicate with
other service, Asterisk. Rtpproxy and WITH_NAT are set up
according to instruction.<br>
<br>
</div>
However, I notice when kamailio communicates with Asterisk
(which is on the same LAN subnet), a lan IP is passed to
Asterisk.My sip client on outside public network does not
receive any audio stream.<br>
<br>
</div>
Is it wrong with the Kamailio setup?<br>

if the users are behind nat, install rtpproxy and enable
WITH_NAT in default config file. Read the comments at the
top of kamailio.cfg to see how to set the control socket
for rtpproxy.<br>

<div>1. No audio</div>
