I am trying to make a test setup to test the RTPENGINE.</pre><pre id="yui_3_16_0_ym19_1_1464683615850_455819"><br></pre><pre id="yui_3_16_0_ym19_1_1464683615850_455819">Case 1:
Now my setup is Kazoo . i.e.:
Subsriber A ---Asterisk (192.168.175.136)-----via NAT(10.111.101.3)-------------Kamailio(10.10.11.104) ----FreeSwitch(10.10.11.104)
Subscriber B is connected directly to Kamailio (this subscriber is in the same network)

When A calls to B - the sound both ways, so it is ok.

Subscriber B is connected directly to Kamailio (this subscriber is in the same network)
WITH RTPENGINE:
When A calls to B - the sound is absent, no sound.</pre><pre id="yui_3_16_0_ym19_1_1464683615850_455889"><br></pre><pre id="yui_3_16_0_ym19_1_1464683615850_455889">I compared both dumps the difference only in addresses</pre><pre id="yui_3_16_0_ym19_1_1464683615850_455889">And what I read in nathelper module:</pre><pre id="yui_3_16_0_ym19_1_1464683615850_455889"><div style="font-family: Helvetica, Arial;
