Do they have a common criterion? If they do not have a common criterion, it is probably not logically possible to associate them. Asterisk is a back-to-back user agent, so it builds out distinct legs for every call with unique Call-IDs and dialogue tags. This makes it hard to meaningfully associate call flows like this inherently, unless you do state tracking in the software to make this possible. This has been an ongoing topic of discussion periodically on the Asterisk Developers' List (asterisk-dev). It seems there is considerable interest in reworking the CDR engine to account for this type of situation more meaningfully. You may wish to search the list archives for greater insight into what core developers are thinking, or to join the list and add your two cents to what you want to see from it. You're definitely not the first person to run into this or regard it as a serious impediment. :) Cheers, -- Alex Balashov Evariste Systems Web : http://www.evaristesys.com/ Tel : +1-678-954-0670 Direct : +1-678-954-0671 _______________________________________________ Sign up now for AstriCon 2007!
