    SIP & Network

    Calls Per SecondCPS

    The rate at which new call attempts are offered to a network, and one of the clearest early indicators of an automated dialing campaign.

    Legitimate business traffic ramps up gradually and follows business hours. Illegal campaigns and compromised PBXs typically appear as a near-instant jump to a sustained high CPS rate, often outside business hours.

    CPS limits per customer and per trunk are a standard protective control and also protect your own signaling infrastructure from overload.

    Why it matters to carriers

    A CPS ceiling tied to each customer's declared traffic profile catches both fraud and honest misconfiguration within seconds instead of hours.
