<p class="MsoNormal">Good morning,<br>
<br>
I'm using freeswitch Version 1.8.2 -3-a98a958ac3 64bit, and i have an issue with the following scenario :<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">I bridge an outgoing call through a PSTN gateway, using group_confirm_key = exec, mainly to ask the called party confirmation before establishing the call.
<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal">To do this, i use group_confirm_key=exec to start a lua script that :<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal">* Plays a vocal prompt to warn the calleR party that he has to wait for his call to be accepted.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal">* Plays a vocal prompt to request the calleD to press a DTMF to confirm that he accept the call.<br>
<br>
This worked fine until i start dialing numbers that make the PSTN gateway to return a 183-session progress before 200-OK.<br>
When this happen, the group_confirm script is triggered on reception of 183-session progress : before the calleD party actually has answered the call !<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">Maybe i'm missing something, but I don't get why group_confirm_key=exec start on 183-session progress, as per my understanding, confirmation message should be requested only when B party has answered (200-OK).<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal" style="margin-bottom:12.0pt"><br>
Does somebody knows how group_confirm_key=exec is supposed to work ?<br>
Should this be reported as an issue ?<o:p></o:p></p>
