[SR-Users] Limiting concurrent calls

[Aft nix]

Hi,
I need to limit the number of concurrent calls go through kamailio.
Its a simple set up(Not per user basis, a global limit will suffice).

I know i need to employ dialog module. But i'm a little confused about
profiles. I thought for simple application like this, i may be able to
use profile altogether.

Any code snippet to limit number of concurrent calls will be very helpful.

Thanks in advance.
