We are using the dispatcher module to send calls to the asterisk clusters in round robin and failover algorithms. <o:p></o:p></p><p class=MsoNormal>We need a solution to fail a call and hand it over to another asterisk server after Kamailio has received a 200OK from Asterisk server A. I understand the failover works before the 200OK is sent from asterisk A and calls can easily be sent to asterisk B but again the challenge here to fail the call over to another asterisk server after a 200OK is received from the first one.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>If this is impossible I was wondering if refer and re-direct is an option to get this done. Thanks in advance for looking at this and for your responses. <o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal><o:p> </o:p></p></div></body></html>
