I wouldn't say the ISDN card is a requirement. You'll need some way of 
attaching your Kannel box to the internet to receive content
from live sites. This could be using ISDN but would probably be better using a 
LAN if you have access to the internet via a LAN.

The other concern is how your subscribers attach to the kannel box. Do they 
have a dial-up account they could use to access your
network? If not, you'll need to provide some sort of modem pool and ISDN cards 
might be a solution here. The best solution would be
for your subscribers to use an ISP so you don't restrict access by having only 
a few lines into your box.

Yes, although analogue lines take longer to answer calls.

Yes, as above. If you have internet access via a LAN it's probably the best 
solution and Kannel should be able to take advantage of
it.

which supports HTTP connections on port 80. You will need to listen for 
incoming connections from mobiles. If these are attaching to
your network through a modem pool they can have the private IP address of the 
kannel gateway so long as they have a route to access
this from the dial up connection.

If your subscribers are attaching from the internet or an ISP, network 
operator, etc. then you need to make the WAP ports 9200,...
available on a public IP address. This doesn't mean the kannel box has its own 
public IP address, but it will otherwise need a port
mapping through a firewall so it looks like it does.

Hope this helps,

Kevin
