Received several calls from Ontario, CA (613) 216-2172 with no message.  Called back and no company name was given, so I hung up.  Now I'm charged for two international calls to Ontario, Canada, which totaled over $6 with all the taxes and carrier cost recovery fee.

It's a scam.

These people should be shut down because they use automated machines and do not allow you to tell them to stop.  Their mailbox is "full."

A long-winded recorded message.  I left the phone on the desk while I worked.  After about 10 mins. I picked it up they were just winding down, asking if I would write my congressman, etc. about health care.  Seemed to be AARP or AARP affiliated.

CALLS EVERYDAY... leaves no message. I called back requesting to be removed

When the phone rang, at 7:45 PM EDT today, I got a recorded message telling me about President Obama's mortgage assistance plan, and telling me if I wanted and was eligible for Federal Assistance, press "1"

The woman who answered the phone had a faint Indian (or similar) accent.  She immediately started into her copy on "would you like to save money on your mortgage?"  When I asked why the US Federal Government would be using a phone number in Ontario CA, she said "I get that a lot.  Why do you say that?  I am in Sunny Southern California!"  I told her that Caller ID had given her away.

I then asked which agency she represented.  She said it was "National Mortgage" but was not affiliated with the US Government.  I asked "so this is a private firm?"  "Yes, sir, it is."  I then informed her I am on the National Do Not Call list and did not want to be... well, called again, but at that point, she said "Have a nice day sir" and hung up on me.

They call again, I will try to get an address.  Then my lawyer will be talking to them.  He's good.  And a violation of the DNC is a fine of up to $1000 per call, I do believe...
