Man asks to speak to wife by first name. Ask if I can take message. "No message thank you"
Must be a solicitor because I think I could hear other operators in background

Who is calling.  Everyday call - never leaves a message, no caller ID other that phone number??

How can this be blocked?

According to this watchdog website, http://www.military-money-matters.com/foundation-for-american-veterans.html , this number is a charity solicitation to "help" veterans, but only about 13 cents of every dollar raised is spent on "program goals". (I did not answer when they called, so I can't confirm the caller's identity, but I have no reason to doubt it.)
Also see the Washington Secretary of State's website, http://www.sos.wa.gov/charities/search_detail.aspx?charity_id=20279 , for more information about this.

In all likelyhood, the call actually came from Associated Community Services, a professional fundraiser, who according to the same website, http://www.sos.wa.gov/charities/search_detail_cfr.aspx?cfr_id=364 , keeps 59 cents of every dollar raised, and passes 41 cents to the charity.
So apparently, if you give $20 to ACS, they keep $11.80 and give $8.20 to FAV, who passes $1.54 to services for veterans.

As for blocking this (or any other pesky) caller, contact your phone provider about "selective call rejection", that works until they start using another number.
