A mini frame is simply a frame containing minimal information about the call itself (the meta data), and a full frame contains all of the meta-data information. Sending mini-frames is part of the IAX protocol, as a way of saving significant bandwidth over the course of a call. However, a mini frame cannot be interpreted correctly independently of a full frame. In every media stream, a full frame is send approximately once every 60 seconds, to sync the timestamps. You could think about it in a different way, by considering a video encoding method, whereby the full image is sent every once in a while, but only the differences (which are much smaller) are sent most of the time. If you have only a frame containing the differences to an image that you never got in the first place, then it's very difficult to know what to do with that. > I'm running Asterisk 1.4.11 on debian Etch. There have been many changes, bug fixes, and even security issues fixed since 1.4.11. I'd really recommend that you try something more recent (and even the latest, because we fixed 2 security issues in the latest release, 1.4.21.2). -- Tilghman _______________________________________________ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- AstriCon 2008 - September 22 - 25 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
