They called about 5:00 PM Eastern Standard time and waited a few minutes after I answered to hang up. Tried to call it back and it was a busy signal.

Caller ID says "RSQUARED". They leave no message.
There is a telemarketing firm of that name (see http://www.rsquaredtelecom.com/home/). I'm assuming it is them, so I didn't call back.
Likely someone begging for money. Likely relentless. Likely will take a sizable portion of any donation. Likely will sell your number if you respond in any way. Don't answer or call back. Block them.
