<p class="MsoNormal" style="margin-bottom:12.0pt">Hello,<o:p></o:p></p>
</div>
<p class="MsoNormal" style="margin-bottom:12.0pt">I am facing an issue when using opensips to serial fork Invites to some SIP gateways and using freeswitch in the middle as b2bua to send calls. That means if first Invite fails opensips will pick next available
gateway and append branch to send this again to freeswitch.<o:p></o:p></p>
</div>
<p class="MsoNormal" style="margin-bottom:12.0pt">But I have noticed when first gateway sends a failed response (and freeswitch log shows call destroyed) and second invite is sent (Same call id, cseq but different branch tag) , freeswitch seem to have old transaction
alive and sends 482 Request merged response.<o:p></o:p></p>
</div>
<p class="MsoNormal" style="margin-bottom:12.0pt">I saw in mail archives that it was discussed few years back but there was no conclusion.
<o:p></o:p></p>
</div>
<p class="MsoNormal" style="margin-bottom:12.0pt">Is there a reason freeswitch keeps transaction alive (for 4 seconds I think) even if it received "ACK" for failed response?<o:p></o:p></p>
