Insurance is not a commodity that you can sell like stock.  There is no "good pitch" for life insurance that you can deliver over the phone.  You must do a complete assessment of client needs.  This involves a total needs approach.

Just call and try to get an appointment.  When they press for more details, you should state "I can show you better than I can tell you" and suggest an appointment time.

Also, you might want to consider a guaranteed UL.  The premiums will be much more reasonable than whole life insurance for the same amount of coverage and the contract period will be similar.
