I have heard that.  In fact originally I started looking at this 
differently - that I could couple a SLIC design with the Raspberry Pi to 
make an FXS ATA, using the Pi's audio jack and the GPIO, with some kind 
of mic...  I found this:

An old (expired!) patent for a SLIC with discrete components... might be 
a fun project...

I got talked into looking for a USB based solution by a friend, which 
seemed like an easy way out.  Until I discovered that it just doesn't 
exist :)
