</div> ^^^^^<br>
The error IS clearle explained, isn't?<br>
<br>
Please check the doc about t_relay():<br>
<br>
<a href="http://www.kamailio.org/docs/modules/devel/tm.html#id2506628" target="_blank">http://www.kamailio.org/docs/modules/devel/tm.html#id2506628</a><br>
<br>
"This function can be used from REQUEST_ROUTE, FAILURE_ROUTE."<br>
<br>
<br>
You can't use t_relay in on_replyroute (in fact you don't need it at<br>
all, t_relay is used to send *requests*).<br>
<br>
Again, please read the documentation and tutorials instead of trying<br>
anything with no reason.<br>
<br>
Regards.<br>
