I have checked it, and that led me to bridge.c. Perhaps I wasn't clear
enough. These are the channels involved in attended transfer:
(transferee) <> (transferer1) (transferer2) <> (transfer target)
Transferee and transfer target are not readily available in
res_pjsip_refer.c, but I can get them in bridge.c, as long as both calls
are bridged. But transfer target may be in ringing state, and in that
case there is no bridge whose members I can check. Also, there could be
multiple ringing channels. So in that case, I need a way to get all
ringing channels which belong to transferrer2 channel. I was wondering
if there is an existing method for that, or do I have to devise my own.
The only idea which comes to mind is to iterate over all channels in the
system and compare their LinkedId to transferer2 UniqueId.

Hello,
I am using chan_pjsip.
Check res_pjsip_refer.c you may be able to intercept both channels there.

Hello,
I am trying to modify bridge.c (function
ast_bridge_transfer_attended)
in order to send channels involved in SIP attended transfer
to the
dialplan. If both transferee and transfer target are bridged,
that is
relatively easy. However, if transfer target is ringing, I
don't know
how to find B-leg channels (there could be multiple, I
suppose). So the
question is, having a reference to A-leg channel, how to
obtain a list
of B-leg channels?
Best regards,
Which channel driver are you using?
