Hi, I can't have a blind transfer work properly if I use bypass-media=true. My first message may have been unclear, here I added excerpt from the dialplan: <!--- ext MyIVR --> <extension name="Extension MyIVR" continue="false"> <condition field="destination_number" expression="^337$"> <action application="set" data="bypass_media=true"/> <action application="bridge" data="sofia/internal/337@10.10.5.51"/> </condition> </extension> <!--- ext MyServ --> <extension name="Extension MyServ " continue="false"> <condition field="destination_number" expression="^3341$"> <action application="set" data="bypass_media=true"/> <action application="bridge" data="sofia/internal/3341@10.10.5.48"/> </condition> </extension> The connection to MyIVR works. Then it sends Refer-to (3341@...) which fails as I described it in the previous mail. I would like to know if the feature has been validated and if I'm missing something in the configuration. Any help would be very appreciated. Thanks!

I want to have some logic on top of FS and also use the fail over mechanism. in short, I have something like this: (third party) A side --- FS ---- B side (IVR server) the IVR the sends a REFER to FS. I don't want A to deal with it. now say B refers to C, it would be considered as a "group" C1, C2 ... to which I want FS to failover. only when one has answered should A be updated (REINVITE) and B notified and disconnected. if all fails I would expect B to be notified of the failure and proceed as I wish without "losing" A. from what I've read FS should be OK for the job but I have a couple issues: 1 ) I have some issues getting FS handle a REFER while in bypass-media mode. (I tried with the release and some revisions including latest) first when I bridge A and B everything is fine and media is bypassed. When B sends REFER to C: - FS immediately NOTIFY B of success and send a reinvite to A with SDP containing its own media IP/port. - then it does INVITE C with A's SDP. - B gets disconnected. A is not updated with C's sdp. so at this point A sends RTP to FS and C sends RTP to A. ... I basically have one extension for B: (set bypass-media and bridge to B) and another extension to C which does the same actions. what do you think I do wrong? 2 ) how can I catch the REFER and set variables from it? (like ref-by or ref-to) in the dial plan I do catch the INVITE sent to C, but how to do it with the REFER itself? thanks for your help! Best Regards, Victor.
