[Spce-user] Concurrent calls not going above 550

[Daniel Grotti]

Hi Pedro,

how is your test scenario ?
How long does a call last ?

For example:
If you get about 500 concurrent calls with 20cps it looks like you have

20cps * 25sec = 500cc

so, if your calls last 25 seconds you will reach 500 cc after 25 sec
(with 20cps), after that the calls will start to be hung up (with BYE).
So after 25sec the different between new calls created and calls hung up
will be stable around 500cc.

br,
Daniel
