First time I received a call from them. I never answer a call that I do not know. Web search does not find much on the number. I have added this number to my "Nuisance numbers" group folder in my address book. This way when I receive a call from unlisted numbers my computer will list who is calling.

Program I use: Caller ID, Shareware $20 by apimac.com, very basic program but does what I need it for. Installed it on 24 Oct 2009

As of 12/4/2009, I have 15 listings with 34 phone numbers that are no longer "unknown" to me. And of course, I still do not answer the phone for them, but now I have some idea who they might be.

this number is for big time bats. they sell high end sports collectibles.

Yes, the call is from Big Time Bats.  I purchased something from the in the past so I assume they are calling to sell something else...
