I think you will find varying responses to your call for "cold-calling" advice. Many agents regard cold-calling as door-to-door, while others think telemarketing. Always ask "what do you mean by cold-calling?" Take advantage of your status as a newbee, you will be cut some slack. Old schoolers will assume door-to-door because that's the way they cut their teeth. More recently (since the invention of the "talking tube") those who make unsolicited phone calls are said to be "cold-calling".
All seriousness aside, where you get into trouble is trying to determine the regulations in instances where non-insurance people use professional jargon they know nothing about and incorporate it into laws. CMS is a good example. Door-to-door solicitation is forbidden, but making telephone calls to set appointments is encouraged. Both are "cold-calling" stategies, but one is illegal and the other not. Sometimes bulletins will be promulgated that use the term "cold-calling" and will raise a ruckus because the nim-wits making the rules don't know what they are talking about. JMHO.
