Cordless Phones

Okay, well I'm sick of the single tone, corded phone we have at work... The phone dispatch uses, when we have a call... is the same phone that other people call. It's kind of annoying when it rings, and you get up thinking there's a call, but it's some random person wanting to talk about their day and what they ate. Adrenaline gets going, then you have to talk about Subways new menu items and the weather.

Does anyone know of a cordless phone (or non-cordless) where you can set different ringers for different numbers?

Thankssss
