What I want to know is how "the regularity of completed calls, call duration, long-term inactivity, range activity, or successful incoming traffic" translates to a trust score. Do less trustworthy people tend to make longer or shorter phone calls than more trustworthy people? And what even is range activity, not to mention how does it relate to trustworthiness?
I haven't worked with Telesign data but I can attempt a guess. Think of how a fraudster uses a phone versus how a legitimate customer uses a phone:
1. The former is likely using a throwaway phone number, the latter is using an established phone number. You can tell the difference with the number of completed calls over time, call duration etc. Burner phones will have bursts of high intensity activity to several different phone numbers whereas legitimate phones will have lots of successfully completed phone calls over a long period of time to repeating phone numbers.
2. The former will likely place calls all over the country or world as they attempt to raid several bank accounts digitally. The latter will probably have more local calls since they're calling their doctors, schools, etc. This is probably where range activity plays a role.
I'm not defending Telesign or how they collect data - I'm merely saying this data has value in account protection.
