Just missed a call from them. Googled before calling back. Don't know who they are, but w/ all the real estate people in this list, I'm betting search engine optimization or website creation/improvement.
I'm also a Realtor and noticed that other people in the real estate industry have been targeted. Probably because we have publicly available numbers. This number called me twice today and didn't say anything.
I answered the phone and when they said "Global Media" I hung up. I'm a realtor also and figured it was some marketing company trying to sell me something. They didn't call back. I'm also on the DNC list but that doesn't seem to matter anymore.
