OK, I see that RFC4244 relates to history-info. I'm adding this here for reference. > That being said, in > practice, the diversion header is used by several phones.

Is it planned to support in Asterisk both history-info and diversion headers ? (I can't access reviewboard at the moment soI can't check by myself).
