You get one FXO (external) interface with the T100P and one FXS 
(internal) interface with the TDM10B. The TDM400P card that the page 
references is built to host four FXS interfaces, with each interface 
added with a piggyback card.

The alternative DevKit is a good way to go since you get a TDM400P board 
that can be expanded as you go. Also, the S100U (the USB FXS device) in 
the original DevKit is junk, from all accounts (including mine). So this 
new DevKit is a welcome addition.

You can start even cheaper than that by buying just the T100P FXO card 
and making all your internal extensions softphones like the X-Lite for 
Windows and kphone for linux.

Yes it can. Lots of services out there. I believe FeatureTel can provide 
dialtone to an Asterisk server (Jon???). Other services are 
iconnecthere.com and connect.voicepulse.com.

These services provide SIP information which will go into Asterisk's 
sip.conf file. Voicepulse.com offers Asterisk's native IAX protocol as 
an option as well.

I will be putting together an Asterisk class for TriLUG in the upcoming 
weeks which should help get people started with Asterisk.
