<tt>Hi Agalya,<br>
<br>
<tt>F<tt>or the first 180, the <tt>flag is not<tt> set (by
default, the <tt>flags are o<tt>ff), so no drop will be
done<tt> and the e<tt>xecution wi<tt>ll get to the set<tt>flag(),
setting the flag. (only the drop is unde<tt>r
the <tt>IF).</tt></tt></tt></tt></tt></tt></tt></tt></tt></tt></tt></tt><br>

<p class="MsoNormal">I don’t get why we need setflag(FLAG_180);
after we drop the response.

<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.

<p class="MsoNormal">Is onreply_avp_mode controls dropping the
2nd response or setflag(FLAG_180);?<o:p></o:p></p>

<p class="MsoNormal">“FLAG_180”, is this something declared

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">Likewise if we need to define explicitly,
what is the module in which we need to define the flag for
