The Caller ID is EDF ORG which can be found on the web www.edf.org
I'm sure this is a fund raising call from a worthwhile organization working to clean up the earth, which because of Global Climate change and many other issues, is a noble endeavor.
I got a call from them and they did not leave a message. They may be Environmental Defense Fund....a good organization.
They use multiple numbers and identifiers to bypass my blocked number list. Not worthy of support even if this is the charity. Paid solicitors are no different than Do Not Call violators.
