This number also showed on my caller ID as "wireless" caller with a 310 area code, so I picked up the phone.  I said "Hello" several times and finally a male voice came online and said he was from the Firefighters Fund.  I told him not to call my unlisted home number and that I did not appreciate telephone solicitations.  This one is also going on the blocked calls list as they call several times a week always at dinner time.

SPAM

Calls every evening for the last several days.  Telemarketer with fake caller ID.  
Long Live PhoneTray screening - all I get is half a ring and then they are zapped!!!  Funny, 20 years ago there were SO MANY apps like it and now we are down to one (along with modem cards and such :) ).

Call from wireless caller. Silence after answering. Report to ' Do Not Call List'wire
