For a single line you can use a X100P card for inbound and outbound 
calling (it won't make a phone ring though). 
I don't think digium still makes the X100P, but there are a lot of 
clones out there.
I have one you can borrow (X100P).

Other devices that you can hook to asterisk can be found here:

Sipura and Polycom devices seem to work well. 

With any of those cards it's wise to disable any onboard devices that 
you can.
If the X100P or TDM400 card shares an IRQ with something else you can 
have issues with echo and such.
Also sometimes sound card devices are set to record by default and can 
cause echo too.
