Send an email? Most voicemail systems will have a little flashing light on top when you have a message waiting.

If I'm trying to write a tricky piece of code and you keep calling me, a) I will be annoyed and b) my mobile will go off, my email client will go off and the land line will be unplugged from the wall.

What are you going to do now? Put on a gorilla suit and come jump up and down on my desk? Learn some class.
