[*] StarStar Me: Using your name as your phone number

[John Lange]

I didn't mean to imply that Microsoft invented the solution, just that they
"solved" the problem by adopting the correct solution. However I do think
Microsoft does deserve a bit of additional credit because to date they are
the only ones to incorporate a direct sip-to-sip calling solution into the
core of a commercial product.

In the case of Lync, it's becomes more viable because it's part of the
standard implementation. If you setup Lync the standard way it's supposed
to be installed, you get this extra bonus of being able to do sip-to-sip
calls.

One thing I have not had any time to explore is how compatible it is with
non-Lync deployments. Could I call someone on sip.edu for example? As
things stand, probably not but maybe with some work?
