[SR-Users] Kamailio stops accepting calls for few seconds after 80 CPS.

[Aqs Younas]

Dear Hamstra thanks you for your suggestion.

Surely it was pike module that was kicking in and blocking my IP address.
But I am unable to clearly understand these two params of pike module.

modparam("pike", "sampling_time_unit", 1)
modparam("pike", "reqs_density_per_unit", 500)

If I want to block any IP sending more than  500 CPS, what should be the
values of these two params?

Thank you for your time.

Best wishes,
