Even if your presence can be monitored and shared with unified communications, contacting you might still be impossible if your access point (an address, a number etc.) is not available or known.

Now say you have five ways to be contacted (phone, email, paging... you name it), would people like to keep or know five different pieces of information to be able to contact you anytime they want?

unified communications, you will (as at now, ideally) have one access point (one number) through which people can contact you, whether they are using their computer's instant messenger, their softphone, their IP phone, email etc.

One example of such a softphone-based service is VoxOx, which aims at unifying all your communication needs. The best example of a one-number reach service is Google Voice.
