Unified Messaging

I'm shocked my new company--with its mostly virtual and traveling workforce--doesn't offer UM. That is, I have a voice mailbox and an associated number (but no desk/phone) that does not alert me if I get a new message! I could be at a client site and I have to dial in to check my VM. It's unconscionable to me. We have it at home. Do you have UM at home? Work?
