OsmocomDECT for Fritzbox router

Hello, would it be possible to use OsmocomDECT with the Fritzbox router? I try to extend my router Fritzbox 7312 with an application called "Callmonitor" (http://freetz.org/wiki/packages/callmonitor; sorry german only), which has a reverse-search (via internet-telephone-books) to query the name of the caller (query by caller's phone number). I want to transfer this name to my DECT cordless phone. Unfortunately, the manufacturer of the router, AVM in Berlin, does not provide any information about DECT (closed-source). Or could someone help me tracing the software dect_manager (http://www.wehavemorefun.de/fritzbox/Dect_manager) or libdect (http://www.wehavemorefun.de/fritzbox/Libdect.so), because I am not a developer. Best regards, Thomas
