Dear all,<br>      started rtpproxy, enabled nat in cfg file. but still there is only<br>
    connection between two client from different network, unable <br>   to get 
audio if    used kamailio server.<br>
               something more that i should add, except rtpproxy     and 
enabling nathelper from cfg file.<br>
                or else is there any way to debug where it get stuck.<br>
         Thanks in advance.
