Thanks. Actually, I want to have some information about the call transfer just like to queue_log in queue. According to your message, there is no such mechanism to associate the call in call transfer. How about any variable that I can identify the call which is made by call transfer? As I know there is a variable ${BLINDTRANSFER} that will fill in a value in blind transfer. However, I can't find any variable that will fill in a attended transfer. Anyone can advise?
