It's been a while since I updated the ATAPI assembly, I've fixed a couple of minor bugs that were reported and updated the samples to compile with VS2008.  I've also added two new events onto the TapiPhone class so you can see state changes and button presses - somehow I missed that when I added the phone support.

Finally, there's now online documentation available at

Have fun!
