what would really help is also posting the stats of the computer
e.gprocessor speed and memory size , whether multipple pcs or a single
pc
e.t.c. instead of saying I can handle xyz no of concurrent calls

Steve,

Enswitch does a set of database queries at the start and end of each
call to:

1. Route the call, including things like caller and time of day routing.
2. Decide whether the customer has enough credit, and how long to let
the call run before cutting it off.
3. Update the table of active calls.
4. Write CDRs.
5. Bill the call and update the customer's and any parent resellers'
and/or affiliates' balances.
6. Minor tasks such as updating busy lamps, etc.

If calls are short, these tasks take up a larger fraction of the
processor time, leaving less processor time available for mid-call tasks
such as codec translation.
