<HTML><BODY><p style="margin-top: 0px;" dir="ltr">ReInvites like all in-dialog requests are processed in has_totag()/loose_route part. Default kamailio.cfg has almost identical part for this purpose.</p>
<p dir="ltr">Main idea is that an initial request (non in-dialog) hasn't To tag already. It appears only when your request "hits" remote side (called or callee, as you wish) and goes back to you. Simplified, but I hope you got an idea :)</p>

<br>
Thank you for your reply.<br>
<br>
Does below config forward all sip requests coming from the customer to the supplier , and relay sip replies back to customer ?<br>
<br>
Where re-invite packets are handled in the below config file?<br>
<br>
Thank you <br>

Try this for a main request route:<br>
<br>
---<br>
<br>
route {<br>
if(!mf_process_maxfwd_header("10")) {<br>
sl_send_reply("483", "Too Many Hops");<br>
exit;<br>
}<br>
<br>
# Maybe some sanity_check() here. <br>
<br>
if(has_totag()) {<br>
if(loose_route()) {<br>
if(!t_relay())<br>
sl_reply_error();<br>
<br>
exit;<br>
} else {<br>
if(is_method("ACK")) {<br>
if(t_check_trans())<br>
t_relay();<br>
} else<br>
sl_send_reply("403", "Forbidden");<br>
}<br>
<br>
exit;<br>
}<br>
<br>
# CANCELs / branches.<br>
<br>
if(is_method("CANCEL")) {<br>
if(!t_relay_cancel()) {<br>
sl_send_reply("500", "Server Internal Error");<br>
exit;<br>
}<br>
<br>
exit;<br>
}<br>
<br>
t_check_trans();<br>
<br>
if(is_method("OPTIONS")) {<br>
sl_send_reply("200", "OK");<br>
exit;<br>
} <br>
<br>
else if(is_method("INVITE")) {<br>
# Route your calls.<br>
<br>
exit;<br>
}<br>
<br>
sl_send_reply("403", "Method unsupported");<br>
exit;<br>
