I get calls from this number and ignore them.
Have entered the name "DO NOT ANSWER!" in my cellphone, which takes calls switched from my home phone.
Another tactic when I am called from a solicitor.
I play the role of stalker and ask, "What are you wearing?"
If they describe innocuous outer clothing, "No. I meant what are you wearing under that?"
One woman told me I couldn't talk to her like that but I reminded her that she had called ME.
Just act real friendly and swarmy and see if you can get under their skin.
Like email and social networking requests from folks you are not familiar with, same goes with phone calls - DO NOT RESPOND OR PICK UP. Also be careful about calling back numbers to see who they are. I did this a few times and the next thing I knew 3rd party long distance charges were showing up on my phone bill (also known as slamming, I think). I chose Sprint as my own long distance provider and I was seeing LD charges for companies I never heard of. I had to fight tooth and nail with Qwest/Century Link to get these charges off my bill. Just use common sense and don't answer if you don't recognize the number.
Calls, hangs up when they get my answering machine. I'm on Do Not Call list. Very annoying!! I have caller ID and I don't answer the telephone if I don't recognize the number.
