I’ve been unable to simply press the TALK button while looking at the Caller ID on the phone to call someone back.

Uniden chose to display everything except the number 1 in front of a number.  I’ve never seen another Caller ID system do this.

So I called Uniden support and they solved the issue in 5 seconds (after being on hold for nearly an hour).

THE SOLUTION:  While looking at a number in Caller ID, press the * key.

That’s it.  A 1 appears in front of the displayed number.
