It is. It would be better if you said: Have you called her lately?

It's wrong. Have you called her lately?

Not exactly correct, as you have it. Have you called her lately - correct. Did you call her last week? Did you call her when you said you would? - correct Yes, I have called her several times (not specific on when) - correct. Yes, I called her last Tuesday. I called her when she said she would be home. - correct

Umm... It is in the comments of my answer.

This is why we will say Have you called her lately.
