[asterisk-users] Attended Transfer with REFER

Hi guys,

I am wondering (and have been unable to find out thus far) whether Asterisk
sets some special channel variables or something when a call is transfered
with the REFER method.
Basically, I'm trying to figure out if it is possible to somehow get a
transferred call back to the transferrer (as it is done with the built-in
atxfer) after X seconds (or an unsuccessful attempt).

Using a timeout in the Dial command is not suitable unless I am able to tell
somehow that the call in question is being forwarded (which is of course not
the case, as the Dial command is called befer the REFER is sent).

Can anyone think of a way to get the call back to the transferrer after this
timeout?

Best regards,
Örn Arnarson
