In Cox Call History? "Missed" is if you were on the phone during the call. "Incoming" is your phone rang during the call.
Both entries should not be there unless the call dialed immediately after detecting a busy signal. Some scammers will immediately dial again after detecting a busy signal because it could bypass Nomorobo or a local call-blocker.
Cox should log it as "Missed" each time...if you were on the phone.
Both call history and on the tv caller id. I never answer the phone when unrecognized numbers call and haven't been on the phone anytime this happened. It seems it has been happening only since August 2dt. More calls than usual too - it's just annoying and making me curios.
