In my bridge, the “back up” expensive gateway starts connecting after only 8 seconds. Using your schema, in some cases, the first or “cheap” gateway takes the full timeout limit to expire. Only then, after 25 or 30 seconds, does the backup start trying to connect. Too many users give up after 20 or 25 seconds of silence. Few will wait for a 25 second timeout, followed by a 12 to 15 second connection.<o:p></o:p></span></p><p class=MsoNormal><span style='font-family:"Verdana","sans-serif";color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-family:"Verdana","sans-serif";color:#1F497D'>But, if error detection is not possible in the sequential dial way, I like your approach, but with an extra “play” message saying “ooops, rerouting, hang on, hang on I can do this”<o:p></o:p></span></p><p class=MsoNormal><span style='font-family:"Verdana","sans-serif";color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><b><span style='font-size:10.0pt;font-family:"Tahoma","sans-serif"'>From:</span></b><span style='font-size:10.0pt;font-family:"Tahoma","sans-serif"'> freeswitch-users-bounces@lists.freeswitch.org [mailto:freeswitch-users-bounces@lists.freeswitch.org] <b>On Behalf Of </b>Michael Collins<br><b>Sent:</b> Friday, May 17, 2013 7:17 PM<br><b>To:</b> FreeSWITCH Users Help<br><b>Subject:</b> Re: [Freeswitch-users] Detecting Errors when dialing through multiple gateways<o:p></o:p></span></p><p class=MsoNormal><o:p> </o:p></p><div><p class=MsoNormal><o:p> </o:p></p><div><p class=MsoNormal style='margin-bottom:12.0pt'><o:p> </o:p></p><div><p class=MsoNormal>On Fri, May 17, 2013 at 1:53 PM, Sean Devoy <<a href="mailto:sdevoy@bizfocused.com" target="_blank">sdevoy@bizfocused.com</a>> wrote:<o:p></o:p></p><div><p class=MsoNormal><img border=0 width=31 height=31 id="_x0000_i1025" src="cid:image001.gif@01CE53EA.3573D780"><o:p></o:p></p><div><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'><span style='color:#1F497D'>Hi All,</span><o:p></o:p></p><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'><span style='color:#1F497D'> </span><o:p></o:p></p><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'><span style='color:#1F497D'>I have been having pretty good luck with redundancy by dialing through multiple gateways like:</span><o:p></o:p></p><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto;text-autospace:none'><span style='font-size:9.5pt;font-family:Consolas;color:blue'><</span><span style='font-size:9.5pt;font-family:Consolas;color:#A31515'>action</span><span style='font-size:9.5pt;font-family:Consolas;color:blue'> </span><span style='font-size:9.5pt;font-family:Consolas;color:red'>application</span><span style='font-size:9.5pt;font-family:Consolas;color:blue'>=</span><span style='font-size:9.5pt;font-family:Consolas'>"<span style='color:blue'>bridge</span>"<span style='color:blue'> </span><span style='color:red'>data</span><span style='color:blue'>=</span>"<span style='color:blue'>sofia/gateway/cheap/1xxxxxxxxxx, [leg_delay_start=8]sofia/gateway/expensive/1xxxxxxxxxx</span>"<span style='color:blue'>/></span></span><o:p></o:p></p></div></div><div><p class=MsoNormal style='margin-bottom:12.0pt'>I'm curious why your're doing simultaneous dial instead of sequential dial here.
