<p>Hello,<br>
</p>
this is the behaviour required by rfc, to send cancel only after
receiving a provisional reply 1xx.<br>
<br>
The cancel_b_method parameter is there to control this behaviour,
but it may apply only to the case when the cancel is received and
needs to be forwarded, so this needs to be investigated for
t_cancel_branches("others").<br>
<br>
Perhaps the best is to open an item on issue tracker from
<a href="http://github.com/kamailio/kamailio" target="_blank">github.com/kamailio/kamailio</a> not to forget about it -- these days
are rather busy, with the freezing of the release in few days.<br>
<br>
Cheers,<br>

<div dir="ltr">Greetings list,
<div>I am forking a call to multiple destinations and want to
keep the only branch which sends quicker first 180/183 reply
and cancel the remaining branches. Below is my related
cfg snippet.</div>

<div> xlog("L_INFO","cancelled all
other branches\n");</div>

</div>
<div>...</div>
<div><br>
</div>
<div>But I see kamailio does not instantly send CANCEL to other
branches after it has received 180/180 from any branch. </div>
<div>Kamailio is sending CANCEL to other branches after they
start sending 180/183 one by one. How can I cancel all other
branches instantly?</div>
<div><br>
</div>
<div>I am sure there is something wrongly configured in my
configuration. </div>
<div><br>
</div>
<div>Any suggestion is much appreciated. </div>
<div>Best Regards.</div>
