Hi,<br>
<br>
default kamailio config file(its routing part) already has rtpproxy
support in case if WITH_NAT is defined.<br>
And there is no problems when NATed subscribers calls one to other...<br>
I have problem only with PSTN and only with incoming call.<br>
<br>

<div>I'm not overly familiar with rtpproxy as we use mediaproxy but
you will need to engage it somewhere in your script, are you doing that?</div>
<div><br>
</div>
<div>Take a look at <a href="http://www.voip-info.org/wiki/view/Kamailio+1.5.x+and+RTPProxy" target="_blank">http://www.voip-info.org/wiki/view/Kamailio+1.5.x+and+RTPProxy</a></div>
<div><br>

<div>Can you see any rtpproxy messages in syslog?</div>

<br>
I have kamailio installation WITH_PSTN, WITH_NAT and rtpproxy.<br>
Using following scenario:<br>
[kamailio]<-sip trunk ->[asterisk gw] <->sip trunk
<-> [PSTN provider]<br>
<br>
All kamailio sip subscribers are behind nat in different networks.<br>
<br>
1. OK. Local kamailio users can call one to other even they are on
different networks behind nat.<br>
2. OK. Outgoing calls from kamailio users to PSTN work also very well.<br>
3. Not OK. Incoming from PSTN side calls have only one way audio.<br>
<br>
I tcpdump'ed kamailio box and found, that pstn provider sends RTP
packets to kamailio IP in case of answered call.<br>
<br>
I guess that rtpproxy is not active in case of pstn call. Is it true ?<br>
<br>
I am using more less default kamailio config<br>
<br>
Could you please suggest solution ?<br>
<br>
