<br>
you can force the destination of a packet with:<br>
<br>
$du = <a class="moz-txt-link-rfc2396E" href="sip:ip:port;transport=tls">"sip:ip:port;transport=tls"</a>;<br>
t_relay();<br>
<br>
or use t_relay_to(...) or t_relay_to_tls(...) functions from tm
module (see its README).<br>

You can execute a RPC command from config file using jsonrpc module
and then can access the response using a json module like jansson:<br>
