It's added for each channel, but as you know, the dialplan
processing
only involves the caller's channel.
The channel variables was just a bad hack. Someone
contributed code
for RTCP, but did not make the report available. After
sending out
several mails to the mailing lists asking for input on what
to do with
it, I added the channel variables just to be able to check
that I got
any data. Another developer then fixed these so that they
worked for
more call cases. Feel free to suggest modifications and
improvements,
but please don't use phrases that insinuate that we had no
clue. You
are not encouraging us to answer you that way.
Reaching the outbound channel from the dialplan, especially
after a
hangup, will be tricky. So what you might want is that the
bridged
channel (outbound) sends the data across the bridge at
hangup time,
maybe in the control frame.
Patches are always welcome!
