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!
