It seems to me that this has to do with the fact that in 999, the dialog is kept in an early state and is never actually answered. Thus, technically tt-weasels is in-band ringback, and no actual call took place. What I'm a little hazy on is which dial plan applications imply a full Answer() and which don't; I do not remember if Playback() is one of the ones that doesn't imply it, but if that's so, it would explain the lack of CDR. Its cousin Background() implies an answer for sure, as that requires a bidirectional media path for possible DTMF input from the user that may preempt the announcement. There is a very limited amount of things that can actually take place in the dial plan that don't require picking up the call (200 OK) and establishing a bidirectional media path; basically, it's the set of actions that involve playing things to the user unidirectionally. Everything else will trigger an answer if an answer is not required but not explicitly enacted with Answer(). -- Alex -- Alex Balashov Evariste Systems Web : http://www.evaristesys.com/ Tel : (+1) (678) 954-0670 Direct : (+1) (678) 954-0671 Mobile : (+1) (678) 237-1775 _______________________________________________ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- AstriCon 2009 - October 13 - 15 Phoenix, Arizona Register Now: http://www.astricon.net asterisk-users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
