Called me at home.  The phone rang until the answering machine came on.  Left no message.

The same thing happened to me.

Telemarketing junk call.

Hangs up if answering machine kicks in - called it back says "thanks for call Right Research to be removed press 9"

Got a robo call that was very loud and obnoxious.
Called the number back with recording to push 9 to opt out of Wright Research calls in the future.  I pushed 9 but it didn't log that in, so when it repeated press 9 to opt out I pushed 9 once again, still didn't log me out of the calls but just repeated the same thing to press 9 to opt out which I did and it said, once again that I didn't respond and it hung up on me.  I do not want this number to call me at any time in the future and I most certainly don't want Wright Research to ever call me again.  This call came into my home after 7 p.m. which is a blatant intrustion into my home life.  If they call me ever again from any number I do all I can to make sure they never do it again, including but not limited to legal action.
