Actually, The goal is to not limit the functionality by over thinking how things will be used but to provide building blocks to make much more possible. Our analogy for this is that if you take the common lego reference, If you have something cool built out of legos but they are super glued together it limits what you *could* have done had then not been.
The system that David described is indeed ideal. I have mentioned it more than once and its no coincidence that FreeSWITCH plays into that model to a tee. I do not mention it very often because I think understanding that concept alone is valuable advice that I'd prefer not to waste on deaf ears so I recommend you heed his suggestion. Logging direct to DB is not a sin or anything but it's just not very reliable. We have so many ways to process call records as it is. you can use the cdr_csv if you want legacy support from asterisk that you can eventually tweak with templatable output, you can even make a template that generates the log as ready to roll sql statements you can just cat into mysql. We have event_socket + channel_hangup event which has all the same info that the cdr_csv uses to generate the file. We have the XML cdr that is a 3 dimensional view of the call with an account of nearly everything that happend including each application executed, branching records when the call is transferred complete with a timestamp for each occurance. --"However it would be great if freeswitch had the options for extra functionality (auto log rotation, db cdrs etc) so that it meets the peculiarities of every different project." A single cron entry that does kill -HUP `cat freeswitch.pid` and you have automatic rotation in unix. In windows there are several cron equivs and instead of kill you can use an xml-rpc script to call the FSAPI call "fsctl send_sighup" also you can schedule it to happen automaticly with the FSAPI sched_api @300 mygroup fsctl send_sighup A script connected to event socket subscribed to channel_hangup can act as your DB cdr engine and has the bonus that it could connect to N boxes at once as well as be able to tell if the system was in trouble by listening for system heartbeat events and or socket disconnect. Moral of the story, there is more already there than first appears. I've always hated the M$ paper clip so I strive not to bring him back. "It looks like you are trying to run a VoIP termination company! Shall I assume how you want your call details?"
