</div></div>Hi!<br>
You don't start Kamailio in any mode - the decision on whether you respond or forward statelessly or with a stateful<br>
transaction is done entirely in your routing script. If you use functions in the TM/TMX modules, there's a transaction<br>
and Kamailio is stateful. If you use functions like "forward()" or "sl_send_reply" there's no transaction in Kamailio,<br>
and the message is handled without any transaction state.<br>
<br>
Best regards,<br>
/O<br>
