Yes, I suspected as much. I've seen that app_dial keeps a list of
outbound channels, but doesn't store it anywhere. So that's a dead end,
pretty much.

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.
Please don't do that. :)
So, Alice (transferee) is on an existing call (channel transferer1),
she transfers to Bob (transfer target), Asterisk sets up channel
transferer2 to call Bob and Bob is ringing but hasn't answered yet.
Right? Optionally, Alice transfers to a "ring group" which causes
Asterisk to create multiple outbound channels, correct? The only
place I can think of that knows about this is app_dial.

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?
