asterisk users - Feb 2006 - Landmark digital key systems and Asterisk

Anyone integrated Landmark (formerly Southwestern Bell) Digital Key System
phones into an Asterisk installation?  The phones are model DKS930 and the
main CPU for the system is a DKS1224.  I'm hoping to reuse some of the
phones with a new Asterisk install I'm building.

Thanks!
