IM a realtor- EVERY TIME I CALL them on their TOLL free number, this means they will telemarket me 8 to 10 times in a day or so,     SO what I do is I CALL from my GOOGLE PHONE, then they call back AND then I BLOCK them, they are such ASSSS holes. I TOLD THEM just because I CALLED does not meant to dial the s*** out of my number, they do it EVERY TIME so thats why I gave them my "SPECIAL" phone number -   google offers FREE voice mail and FREE phone number, I forward my calls to my GOOGLE number and block all the losers as they call,

THIS IS WHY I HATE calling TOLL FREEE NUMBERS its lke a open inveitation to allow companies to ABUSE your confidential INFORMATION,   so ALWAYS tell companies that you prefer to call them on their NON TOLL FREE number and then BLOCK yours otherwise you are giving them your FULL NAME, HOME ADDRESS and phone number when they get their next bill from their phone company

TRY GOOGLE VOICE
ALSO there is a PRODUCT out there CALLED " CALL BLOCKER" its about $50 and totaly worth it I have it on my land line, I
I BLOCK INCOMING calls from all 800 877 855 numbers    
you can also block SPECIFIC numbers from calling you


ALLIED CALLED ME 11 times today and got a BUSY signal lol  disconected signal
