Some are shareware, some are free. Personally, I've always liked Time &
Chaos16 for both appointments contacts and phone dialing. The 4.95 version
that I bought years ago, on a single 3.5 diskette, puts everything on one
page, is fast and user friendly, has white and yellow pages for your phone
numbers, let's you take notes and date stamp them for called numbers.
Unfortunately when the program went to 32 bit, the interface was changed is
not as simple a GUI. I love that old 16bit version, and use it daily (in
compatibility mode for Windows 95). The 16bit version of Time & Chaos is no
longer available legally. But, you can check out the newest 32bit trial
version at:

Since I get the idea that you're looking for a simple phone dialer, you'll
probably find an acceptable free one on the first link.
