What I do is when ever a call comes in I update a table in MySQL to active = (active +1). On hang up I do active = (active -1).

I have a cron that checks once a minute to see how many active and stores it along with epoch in db.

I then have a graph that shows channel usage. If you want the code let me know.

How do you handle table locking in case more than 1 call arrives 'at the same time?'

How do you handle a crash?

Using group() and group_count() with a bit of AMI to retrieve the count and stuff it in the database sounds like a 'better practice.'
