My prayers about an efficient and effective way to deal with phone solicitors and predictive dialers have been answered.
Through Amazon.com, order for $59:
T-lock Incoming PRO Call Blocker with LCD Display and Blacklist:
Blocks up to 1,500 telephone & fax numbers (up to 16 digits each)
Stores up to 100 telephone numbers as incoming calls
Stores up to 50 telephone numbers as outgoing (dialed) calls
LCD display has 4 levels of brightness
Line-powered (no external power or batteries needed ** Please ignore battery compartment).
plugging it in (took 2 minutes), no more predictive calls have rang my
phone & outfits that do call are easy to thwart by pressing the call
block select button.
