For me, having a bit of OCD, I am slightly put off by the fact that there is more room on the top than on the bottom of the "main" text. I don't fully understand how the word "automatically" fits with the theme, unless there is no other option for a word to use that would give you the "call" text that you are looking for. Other than that, I think it's pretty good. Have you played around with different colour combinations? Just an idea, maybe you could get them printed in various colours.
