<p class="MsoNormal">I have just commented my understanding of each snippet at the same line.<o:p></o:p></p>
<p class="MsoNormal">I don’t get why we need setflag(FLAG_180); after we drop the response.

<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal"><tt><span style="font-size:10.0pt">if ($rs==180) { //We are checking response is equal to 180

<tt> if (isflagset(FLAG_180)) // Checking the flag is set or not. If response is 180, flag will be set</tt><br>

<tt> setflag(FALG_180); ??</tt><br>

<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">(P.S) I tested without setting the flag after drop response. In this case it forwards both 180 response back to caller.
<o:p></o:p></p>
<p class="MsoNormal">Am curious how it controls it.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Is onreply_avp_mode controls dropping the 2nd response or setflag(FLAG_180);?<o:p></o:p></p>

<p class="MsoNormal">Thank you for your kind response. I will try the logic you told me. But I have a question in the below logic.<o:p></o:p></p>
<p class="MsoNormal">“FLAG_180”, is this something declared and maintained by opensips and set by default on its own if Ringing response is received or we need to define this flag explicitly ?<o:p></o:p></p>
<p class="MsoNormal"> <o:p></o:p></p>
<p class="MsoNormal">E.g for setting NAT flag, we are using ‘usrloc’ module and ‘nat_bflag’ as parameter and then value.<o:p></o:p></p>
<p class="MsoNormal">modparam("usrloc", "nat_bflag", "NAT")<o:p></o:p></p>
<p class="MsoNormal"> <o:p></o:p></p>
<p class="MsoNormal">Likewise if we need to define explicitly, what is the module in which we need to define the flag for FLAG_180?
