<p class=MsoNormal>Hi,<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I'm trying to do a POC using FS, the goal is to have FS
handle REFERs containing proprietary data. <o:p></o:p></p>
<p class=MsoNormal>I want to have some logic on top of FS and also use the fail
over mechanism.<o:p></o:p></p>
<p class=MsoNormal>in short, I have something like this:<o:p></o:p></p>
<p class=MsoNormal>(third party) A side --- FS ---- B side (IVR server)<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>the IVR the sends a REFER to FS. I don't want A to deal with
it. <o:p></o:p></p>
<p class=MsoNormal>now say B refers to C, it would be considered as a
"group" C1, C2 ... to which I want FS to failover.<o:p></o:p></p>
<p class=MsoNormal>only when one has answered should A be updated (REINVITE)
and B notified and disconnected.<o:p></o:p></p>
<p class=MsoNormal>if all fails I would expect B to be notified of the failure
and proceed as I wish without "losing" A.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>from what I've read FS should be OK for the job but I have a
couple issues:<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>1 ) I have some issues getting FS handle a REFER while in
bypass-media mode.<o:p></o:p></p>
<p class=MsoNormal>(I tried with the release and some revisions including
latest)<o:p></o:p></p>
<p class=MsoNormal>first when I bridge A and B everything is fine and media is
bypassed.<o:p></o:p></p>
<p class=MsoNormal>When B sends REFER to C:<o:p></o:p></p>
<p class=MsoListParagraph style='text-indent:-18.0pt;mso-list:l0 level1 lfo2'><![if !supportLists]><span
style='mso-list:Ignore'>-<span style='font:7.0pt "Times New Roman"'>
</span></span><![endif]><span dir=LTR></span> FS immediately NOTIFY B of
success and send a reinvite to A with SDP containing its own media IP/port.<o:p></o:p></p>
<p class=MsoListParagraph style='text-indent:-18.0pt;mso-list:l0 level1 lfo2'><![if !supportLists]><span
style='mso-list:Ignore'>-<span style='font:7.0pt "Times New Roman"'>
</span></span><![endif]><span dir=LTR></span>then it does INVITE C with A's
SDP.<o:p></o:p></p>
<p class=MsoListParagraph style='text-indent:-18.0pt;mso-list:l0 level1 lfo2'><![if !supportLists]><span
style='mso-list:Ignore'>-<span style='font:7.0pt "Times New Roman"'>
</span></span><![endif]><span dir=LTR></span>B gets disconnected. A is not
updated with C's sdp.<o:p></o:p></p>
<p class=MsoNormal>so at this point A sends RTP to FS and C sends RTP to A.
…<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I basically have one extension for B: (set bypass-media and
bridge to B)<o:p></o:p></p>
<p class=MsoNormal>and another extension to C which does the same actions.<o:p></o:p></p>
<p class=MsoNormal>what do you think I do wrong? <o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>2 ) how can I catch the REFER and set variables from it?
(like ref-by or ref-to)<o:p></o:p></p>
<p class=MsoNormal>in the dial plan I do catch the INVITE sent to C, but how to
do it with the REFER itself?<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>thanks for your help!<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Best Regards,<o:p></o:p></p>
<p class=MsoNormal>Victor.<o:p></o:p></p>
