8. Sending Recorded Phone Messages (Phone Broadcasting) and the Law: You cannot use phone blasting for telemarketing or sales messages for services or products, without first getting written permission from those on your list.
The difference is subtle and primarily reflected in how we choose to deliver pre recorded phone calls to our customer's contacts. When you think about phone dialers, you’re talking about a service that makes phone calls to connect someone to a live person - typically for the purpose of selling or qualifying a lead.

If you want them to leave a voicemail, tell them right from the beginning, “Please leave your name, reason your calling, and the best way to contact you.” If you want them to call you back during normal business hours, tell them, “Please call back during normal business hours.” If you want them to call back prepared for a lengthy conversation, you can say something like, “Please refer to our website’s FAQ page,” and then provide the URL. Self-service should never be underestimated.
In certain situations, it’s a good idea to let a call go to voicemail. If you’re in a loud area, unable to spend 10-15 minutes talking, or are otherwise distracted, don’t answer. Recruiters who cold-call candidates will understand that you’re simply unavailable – but make sure to return calls in a timely manner. If possible, call back during regular business hours.
