<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"> <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?
