SIP & Network
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.
A CPS ceiling tied to each customer's declared traffic profile catches both fraud and honest misconfiguration within seconds instead of hours.
An automatically dialed call that delivers a pre-recorded or artificial voice message, legal only with the right consent or exemption.
A virtual connection that carries voice calls over IP between a business phone system and a voice provider, replacing physical phone lines.
The unauthorized use of a phone system or account to place calls that someone else has to pay for, usually to expensive international destinations.
The percentage of call attempts that are actually answered, used as both a route-quality measure and a fraud indicator.
