<br>The main task is to configure RTP Proxy with full topology hiding - OPERATOR_1 ------- Freeswitch ------- OPERATOR_2<br>




Here is a prt of my config:<br>- sip profile.<br>I have one new sip profile with two gateways (OPERATOR_1 and OPERATOR_2)<br>&lt;include&gt;<br>  &lt;gateway name=&quot;OP1&quot;&gt;<br>    &lt;param name=&quot;username&quot; value=&quot;X1.Y1.V1.Z1&quot;/&gt;<br>





    &lt;param name=&quot;password&quot; value=&quot;09321234&quot;/&gt;<br>    &lt;param name=&quot;proxy&quot; value=&quot;X1.Y1.V1.Z1&quot;/&gt;<br>    &lt;param name=&quot;from-domain&quot; value=&quot;<a href="http://test.com/" target="_blank">test.com</a>&quot;/&gt;<br>

Refering to <a href="http://wiki.freeswitch.org/wiki/Misc._Dialplan_Tools_start_dtmf" target="_blank">http://wiki.freeswitch.org/wiki/Misc._Dialplan_Tools_start_dtmf</a> and <a href="http://wiki.freeswitch.org/wiki/Proxy_Media" target="_blank">http://wiki.freeswitch.org/wiki/Proxy_Media</a> i have done all the necessary things.<br>





<br>vars.xml<br>  &lt;X-PRE-PROCESS cmd=&quot;set&quot; data=&quot;global_codec_prefs=PCMA,G.729,PCMU,GSM&quot;/&gt;<br>  &lt;X-PRE-PROCESS cmd=&quot;set&quot; data=&quot;outbound_codec_prefs=PCMA,G.729,PCMU,GSM&quot;/&gt;<br>




<br>The after-effect is following output:<br>[ERR] switch_core_io.c:1055 Codec PROXY PASS-THROUGH encoder error!<br><br>Placing  &lt;param name=&quot;dtmf-type&quot; value=&quot;none&quot;/&gt; does not help anyway.<br><br>



Could sb point me where the problem is located?<br><br>Thanks in advance,<br><font color="#888888"><font color="#888888">Mac</font></font></div>
