Good idea. Unfortunately, I can't recall who posts those lists/links.
However, anyone can Google their Senators and Congresscritter and find out the phone numbers (usually both the Washington office and local offices are listed on their web sites).
Maybe these links will help in contacting those that need to be contacted.
