I'm seeking a one-button dialer. You push a button, and it dials the number, pauses and dials the access code. In the early days of MCI Execunet and such; they were as common as bedbugs are now.
The one I want is not portable, wireless or even iPad compatible. It installs inside or next to a 2500-type set, (hopefully) runs off loop current, and has one button. You program it and that's it.
Suggestions? eBay has dozens of "I've fallen and can't get up" units but my searches otherwise come up snake eyes....
