Unknown caller. Did not leave message. Caller i.d. reads "unavailable". If you do not identify yourself via caller i.d. or fail to leave a message, you are immediately added to my call blocking "reject call" list. BLOCKED!!!!  Next time you call your call will not even ring my phone. It will be rejected instantly. Later, dude.

No message left. CID was Novato,CA.
Telemarketers are busy today, its only 9am and I have received 12 calls already, ouch.
Caller ID is Great to have.

I never answer calls from numbers I don't recognize.  If it's important, they'll leave a message.

Unknown number and never b leaves a voicemail so I don't answer.

Not many comments on here, but I have received 15 calls to my blocker in the past 6 weeks. Just lucky, I guess.
Persistence is Futile.
