spam call frusteration

You may try searching for the phone in Google or Bing. As long as the phone number is publicly advertised, you should be able to identify the calling company quite easily.

If the phone number is not public, you may want to try the WhitePages (link removed by moderator) and their reverse lookup feature.

If you already know what kind of company is calling, there are industry-specific DB's online that can be of much help. In my case, I was being called by a debt collection agency called RAB in Texas, (link removed by moderator). I know there are other DB's like that.

My answer is being deleted?

Note from moderator: the links and business names you included trigger the spam filters, this results in your posts being marked as spam, deleted and your posting privileges revoked. Use care when mentioning web sites on the forums (from experience!)
