Thoughts On Unified Messaging Services?

This Clan Anonymous Coward scribe asks: "I have been using uReach for the last eight months now and have become hooked on this whole unified messaging thing. The fact they give you your own 800 number without extension was a big plus. I find I use the service for call forwarding, sending and recieving faxes and consolidating e-mail from other accounts. I would like to know what other Slashdot readers think of unified messaging and what service they use and how they use it."
