[Freeswitch-users] custom call counter

[Michael Jerris]

It depends on the timing of when your increment and decrement are vs when the sql calls to push the events into the tables that are used for show calls are.  Also, the sql calls are batched and queued causing a little delay (less than a second).  If your doing a lot of short lived calls there is sure to be timing discrepancy.  I am sure there is even more discrepancy if you look at the output of status which shows the current number of sessions (those are individual call legs) as that information is a little more real time.
