<tt>Hi Rodrigo,<br>
<br>
Your scenario 1) is not sequential forking, but parallel forking
(if you have multiple callee reached in the same time).<br>
<br>
And 2), yes, it is serial / sequential forking.<br>
<br>
Both are supported by OpenSIPS.<br>
<br>
Regards,<br>

<p>Dear OpenSIPS users,</p>
<p><br>
</p>
<p>When sequential forking is used by means of OpenSIS, <br>
</p>
<p><br>
</p>
<p>1 - can we have every callee ringing simultaneously in
sometime, when nobody answers the call?</p>
<p><br>
</p>
<p>Or <br>
</p>
<p><br>
</p>
<p>2 - each callee will ring only after a previous one stop
ringing if the call was not answered until that moment?</p>
<p><br>
</p>
<p>If the answer is number 2, is it possible to change this
behavior to put all callees ringing at same time in some
moment?</p>
<p><br>
</p>
<p>I would like to experiment sequential forking, just to see if
helps me to avoid an UAC to mute dialogs (vide RFC 3960) when
it receives multiple SIP 183 due to a parallel forking.<br>
</p>
<p><br>
</p>
<p>Best regards!</p>
