[asterisk-users] Maximum number of concurrent calls

[Emrah]

Hi,

I remember reading that Asterisk allows only 100 simultaneous calls. Is
that correct?
If it is so, how is it possible to have a conference call with more then
100 users? I think I read here that some people managed to have 500
people in a conf room...
Or, how do I increase this limit? Is it as easy as changing a value in a
config.h?

Thanks for your help,
Emrah
