Dialing and Smiling
You did something bad in a former life if you ended up getting this job. Think: early stock broker, early subscription magazine sales cold caller, and the like.
As to dialing and smiling–which will actually make you frown...this is the telemarketing strategy of making unsolicited calls. The smiling part comes from the overly friendly manner of the caller.
Also known as cold calling, which sounds grumpier. "Yes, livin' the dream," said no one ever who did this job.
