<p class="MsoNormal"><span style="font-size:10.0pt;font-family:Verdana;color:black">Hi, <br>
<br>
I'm using opensip as a load balancer in front of Freeswitch nodes. <br>
<br>
Opensips Version 1.11 is used for a reason and can't change the version. <br>
<br>
When an INVITE comes from mobile to Freeswitch through Opensips, call will be answered. Then at the end of call, Freeswitch sends BYE to Opensips. <br>
<br>
I want Opensip to convert BYE to Cancel - 480 Temporary not available and forward. <br>
<br>
Please let me know how to do it with Opensips. <br>
<br>
<br>
Thanks, <br>
Pradee</span><o:p></o:p></p>
