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!

Subject: [Freeswitch-users] Bypass-media and REFER method

Hi,

I'm trying to do a POC using FS, the goal is to have FS handle REFERs
containing proprietary data. 

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.
