They are, in order of increasing likelihood of being a spammer/scammer:
DEFINITELY_NOT (-1.0)
ALMOST_CERTAINLY_NOT (-0.8)
PROBABLY_NOT (-0.6)
MAYBE_NOT (-0.4)
UNKNOWN (0.0)
MAYBE (0.4)
PROBABLY (0.6)
ALMOST_CERTAINLY (0.8)
DEFINITELY (1.0)
Not all of these likelihoods will be present in the SPAM Databasedatabase. Typically Typically, 98% or more of the phone numbers in the SPAM Database have an ALMOSTALMOST_CERTAINLY or PROBABLY likelihood. Less than 1% will be MAYBE, and phone numbers with other likelihoods will often not be present in the SPAM Databasedatabase.
The Orchestrator will only allow associating an action (Blocking the Call or Rewriting the Caller ID) for likelihoods with a 0.0 or higher probability.
