Prevent Skype from vibrating/beeping the phone when I'm chatting on the computer

I have Skype on my Android phone, and I'm logged into the same account from both the phone and my PC, but it's annoying that when I'm chatting from my PC, the phone constantly vibrates and beeps with every message. I'm on my computer, not on my phone. Is there a way to make Skype realize that if I'm typing from my computer, it means I'm sitting in front of it (or how else I'm typing there), so it doesn't make noises from the phone?
