J179 SIP as a ringdown

[ITHawkDriver]

A program I support only has J179s and they want a lobby phone to act as a ringdown to a coverage answer group. How do I get it so that when the visitor picks up the handset, it rings a specific number. Running CM 8.1.

SIP hotline is managed via the 46xxsettings file using the handsets MAC address but I can't find any documentation for it
