Hi there and welcome Bob
No sorry, it only has one method to answer and thats the slide. Nearly all phones operate this way. If it was one touch it would be too easy to answer when you pick up the phone to see who is calling, hence the idea behind the slide.
If you would like any additional information or assistance, please do not hesitate to let me know.
Else if you can take a second to rate my service by clicking one of the stars at the top of the screen then submit, that would be greatly appreciated.
