No, Folks- I strongly suspect that this is a number-verification system. Somebody (collection agencies?) pay to have our numbers verified. Other theories?
Called my business office last night late around 8pm. No message left. I called back today. The greeting said it is Comnet - an organization that helps recruit members for non-profits. The messages said that my number was supplied by a non-profit organization with which you have a relationship. I do contribute from time to time to local non-profits. So, it is possible.. Don't know the reason for the call though.
Received NINE calls from this number dating back to 2/6/07. They have never left a message. Today I answered for the first time--no voice. Enough please!
