Our problem was that failover was being invoked on receipt of any rejection code due to the bug described in FS-7678 and this led to the error you are seeing. What we wanted was for failover to only occur if the gateway was actually unavailable, in which case there would be no existing session to be a duplicate of. The solution I described worked for us but perhaps your requirements and scenario are slightly different and Steven's approach would be more appropriate.<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-GB style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><b><span lang=EN-US style='font-size:11.0pt;font-family:"Calibri","sans-serif"'>From:</span></b><span lang=EN-US style='font-size:11.0pt;font-family:"Calibri","sans-serif"'> <a href="mailto:freeswitch-users-bounces@lists.freeswitch.org">freeswitch-users-bounces@lists.freeswitch.org</a> [<a href="mailto:freeswitch-users-bounces@lists.freeswitch.org">mailto:freeswitch-users-bounces@lists.freeswitch.org</a>] <b>On Behalf Of </b>Steven Ayre<br><b>Sent:</b> 29 July 2016 10:35<br><b>To:</b> FreeSWITCH Users Help <<a href="mailto:freeswitch-users@lists.freeswitch.org">freeswitch-users@lists.freeswitch.org</a>><br><b>Subject:</b> Re: [Freeswitch-users] Duplicate UUID<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-GB><o:p> </o:p></span></p><div><div><p class=MsoNormal><span lang=EN-GB>If you set the origination_uuid in {} braces it'll try to use that UUID for all of the B-legs.<o:p></o:p></span></p></div><p class=MsoNormal><span lang=EN-GB><br>You need to set a different uuid for each leg in [] braces, for example:<o:p></o:p></span></p><div><p class=MsoNormal><span lang=EN-GB><br><action application="set" data="uuid1=${create_uuid()}"/><o:p></o:p></span></p></div><p class=MsoNormal><span lang=EN-GB><action application="set" data="uuid2=${create_uuid()}"/><br><action application="set" data="uuid3=${create_uuid()}"/><o:p></o:p></span></p><div><p class=MsoNormal><span lang=EN-GB><action application="bridge" data="[origination_uuid=${uuid1}]sofia/gateway/gw1/12345|[origination_uuid=${uuid2}]sofia/gateway/gw2/12345|[origination_uuid=${uuid3}]sofia/gateway/gw3/12345"/><o:p></o:p></span></p></div><div><p class=MsoNormal><span lang=EN-GB><o:p> </o:p></span></p></div><div><p class=MsoNormal><span lang=EN-GB>fail_on_single_reject wouldn't help you if you're using {} since if you failover to the 2nd leg both 1st and 2nd leg would try using the same UUID<o:p></o:p></span></p></div></div><div><p class=MsoNormal><span lang=EN-GB><o:p> </o:p></span></p><div><p class=MsoNormal><span lang=EN-GB>On 29 July 2016 at 06:36, Petr Parýzek <<a href="mailto:PetrParyzek@seznam.cz" target="_blank">PetrParyzek@seznam.cz</a>> wrote:<o:p></o:p></span></p><blockquote style='border:none;border-left:solid #CCCCCC 1.0pt;padding:0cm 0cm 0cm 6.0pt;margin-left:4.8pt;margin-top:5.0pt;margin-right:0cm;margin-bottom:5.0pt'><div><div><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'>Thanks for reply!</span><o:p></o:p></p><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'>I</span><span lang=EN-CA style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'>'m using uuid created with create_uuid api function, so by my opinion it should be unique.</span><o:p></o:p></p><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'><span lang=EN-CA style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'>The error began occur after I started using operator | for failover.
